1 INTRODUCTION
Congratulations! You are about to install and use a device from the Xtender range. You have chosen
a high-tech device that will play a central role in energy saving for your electrical installation. The
Xtender has been designed to work as an inverter / charger with advanced functions, which can be
used in a completely modular way and guarantee the faultless functioning of your energy system.
When the Xtender is connected to a generator or network, the latter directly supplies the consumers,
and the Xtender works like a battery charger and backup device if necessary. The powerful battery
charger has an exceptional high efficiency and power factor correction (PFC) close to 1. It
guarantees excellent battery charging in all situations. The charge profile is freely configurable
according to the type of battery used or the method of usage. The charge voltage is corrected
depending on the temperature, thanks to the optional external sensor. The power of the charger is
modulated in real time dependent according to the demand of the equipment connected at the
Xtender output and the power of the energy source (network or generator). It can even temporarily
backup the source if the consumer demand exceeds the source capacity.
The Xtender continuously monitors the source to which it is connected (network or generator) and
disconnects itself immediately if the source is missing, disturbed or does not correspond to the quality
criteria (voltage, frequency, etc.). It will then function in independent mode, thanks to the integrated
inverter. This inverter, which has an extremely robust design, benefits from STUDER Innotec’s many
years of experience and expertise in this area. It could supply any type of load without faults, enjoying
reserves of additional power that is unmatched in the market. All your equipment will be perfectly
provided with energy and protected from power outages in systems where energy supply is
unpredictable (unreliable network) or voluntarily limited or interrupted, such as hybrid installations on
remote sites or mobile installations.
The parallel and/or three-phase network operation of the Xtender offers modularity and flexibility and
enables optimum adaptation of your system to your energy requirements.
The RCC-02/-03 control, display and programming centre (optional) enables optimum configuration
of the system and guarantees the operator continuous control for all important parameters in the
installation.
In order to guarantee flawless commissioning and functioning of your installation, please read this
manual carefully. It contains all the necessary information relating to the functioning of the inverters
/ chargers in the Xtender series. The setting up of such a system requires special expertise and may
only be carried out by qualified personnel familiar with the applicable local regulations.

2.4.1 General
This manual is an integral part of the device and must be kept available for the operator
and installer. It must remain close to the installation so that it may be consulted at any time.
The parameter table available at the end of the manual (p. 47) must be kept up to date in the event
of modification of the parameters by the operator or installer. The person in charge of installation
and commissioning must be wholly familiar with the precautionary measures and the local
applicable regulations.
When the Xtender is running, it generates voltage that can be potentially lethal. Work on or
close to the installation must only be carried out by thoroughly trained and qualified
personnel. Do not attempt to carry out on-going maintenance of this product yourself. The
Xtender or the generator connected to it may start up automatically under certain
predetermined conditions.
When working on the electrical installation, it is important to be certain that the source of
DC voltage coming from the battery as well as the source of AC voltage coming from a
generator or network have been disconnected from the electrical installation.
Even when the Xtender has been disconnected from the supply sources (AC and DC), a
dangerous voltage may remain at the outputs. To eliminate this risk you must switch the
Xtender OFF using the ON/OFF button (1). After 10 seconds the electronics is discharged
and intervention may take place without any danger.
Studer Innotec SA
Xtender
User manual V4.5.0 8
All elements connected to the Xtender must comply with the applicable laws and regulations.
Persons not holding written authorisation from Studer Innotec are not permitted to proceed with any

This manual contains important safety information. Read the safety and working instructions carefully
before using the Xtender. Adhere to all the warnings given on the device as well as in the manual,
by following all the instructions with regard to operation and use.
The Xtender, except XTS, is only designed for indoor use and must under no circumstances be
subjected to rain, snow or other humid or dusty conditions. The maximum specifications of the device
shown on the type plate, as at fig. 1b, must be adhered to.
In the event of use in motorised vehicles, the Xtender must be protected from dust, splash water and
any other humid condition. It must also be protected from vibration by installing absorbent parts.
The Xtender can be installed at altitudes up to 3000m. For installations at higher altitudes,
please contact Studer Innotec SA. The Xtender is in overvoltage category III, which
indicates that it can be installed directly after the protection device at the entrance of
a building.
2.4.2 Precautions for using the batteries
The batteries should only be chosen, dimensioned and installed by qualified personnel,
trained in this specific area.
Lead-acid or gel batteries produce a highly explosive gas with normal use. No source of
sparks or fire should be present in the immediate vicinity of the batteries. The batteries
must be kept in a well-ventilated place and be installed in such a way as to avoid
accidental short-circuits when connecting.
Never try to charge frozen batteries.
When working with the batteries, a second person must be present in order to lend
assistance in the event of problems.
Sufficient fresh water and soap must be kept to hand to allow adequate and immediate
washing of the skin or eyes affected by accidental contact with the acid.
In the event of accidental contact of the eyes with acid, they must be washed carefully
with cold water for 15 minutes. Then immediately consult a doctor.
Battery acid can be neutralised with baking soda. A sufficient quantity of baking soda
must be available for this purpose.
Particular care is required when working close to the batteries with metal tools. Tools such
as screwdrivers, open-ended spanners, etc., may cause short circuits. Sparks resulting
from these short-circuits can cause the battery to explode. Therefore, tools with insulated
handles should be used and they should never be left to rest on top of the batteries.
When working with the batteries, all metal jewellery such as rings, watches with a metal
bracelet, earrings, etc., must be taken off. The current supplied by the batteries during a
short circuit is sufficiently powerful to melt the metal and cause severe burns.
Batteries at the end of their life-cycle should be recycled in accordance with directives
from the responsible local authorities or the battery supplier. The batteries should never
be exposed to fire as they may explode. Under no circumstances should you try to take
apart or dismantle the battery, as they contain toxic and polluting materials. For
ungrounded battery systems, always check that they are not inadvertently grounded
before starting work on the batteries.
Always follow carefully the instructions of the battery manufacturer.

3 ASSEMBLY AND INSTALLATION
3.1 HANDLING AND MOVING
The weight of the Xtender can be up to 50kg depending upon the model. Use an appropriate lifting
method as well as help from a third party when installing the equipment.
3.2 STORAGE
The equipment must be stored in a dry environment at an ambient temperature of between
-20°C and 60°C. It stays in the location where it is to be used a minimum of 24 hours before being set up.
3.3 UNPACKING
When unpacking, check that the equipment has not been damaged during transportation and that
all accessories listed below are present. Any fault must be indicated immediately to the product
distributor or the contact given at the back of this manual.
Check the packaging and the Xtender carefully.
Standard accessories:
Installation and operating instructions, c.f. Appendix 1.
Mounting plate for XTH and XTS– fig. 2a (25)(26).
One set of cable glands on the unit and/or apart.
Four M6 screws and washer for XTS to assemble the support and the enclosure.
3.4 INSTALLATION SITE
3.4.1 XTM and XTH
Devices in the XTM and XTH range are designed for indoor use (IP20) and the place of installation
must satisfy the following criteria:
Protected from any unauthorised person.
Protected from water and dust and in a place with no condensation.
It must not be situated directly above the battery or in a cabinet with it.
No easily inflammable material should be placed directly underneath or close to the Xtender.
Ventilation apertures must always remain clear and be at least 20cm from any obstacle that
may affect the ventilation of the equipment.
In mobile applications it is important to select an installation site that ensures as low a vibration
level as possible.
According to the IEC/EN 62109-1 norm, the level of pollution at the mounting place should
not exceed PD2 (second degree environment), which means that there can be pollution as
long as it is not electrically conductive. XTS
XTS range appliances have a high grade of protection (IP54). They can therefore be installed
outdoors, with exposure to dust and water splashes. It is recommended to avoid locations particularly
exposed to salt water splashes which are extremely aggressive (for instance under a vehicle chassis)
or to solvent (motor oil) that can attack all non-metallic parts of the enclosure. Also avoid installing
the XTS in direct sunlight or near a heat source (i.e. engine compartment). The presence of a heat
source may reduce significantly the nominal power of the unit.
Reduce as much as possible exposure to sudden temperature changes as a variation in temperature
may cause undesired condensation inside the enclosure.
The 4 mounting screws of the enclosure must be completely tightened with a torque of
5Nm in order to guarantee the IP 54 protection index. Any unused cable glands should
be closed in a way that guarantees at least the same level of protection.
3.5 FASTENING
The Xtender is a heavy unit and must be mounted to a non-flammable support (wall)
designed to bear such a load
The Xtender must be installed vertically onto heavy duty material (concrete or metallic wall) and
positioned vertically with cable glands oriented down. A sufficient space around it must be provided
to guarantee adequate ventilation of the device (see figs. 2a).

Xtender
User manual V4.5.0 10
3.5.1 Fastening of the XTH model
First fix the mounting bracket (26)) supplied with the device using 2 Ø < 6-8 mm >screws**.
Then hang the Xtender on the bracket. Fasten the unit permanently using 2 Ø <6-8 mm> screws** on
to the two notches located at the underside of the case.
Dimensions of the appliances are given on Fig 2a of the appendix 1.
3.5.2 Fastening of the XTM model
Screw first the top screw (6-8mm **) without washer on a solid wall (concrete or metallic wall) up to
a distance of 2mm between head and wall. Hang the apparatus by taking care to release
beforehand the trap door of access (27 fig. 2a of the appendix) by inserting it inside the apparatus
using a screwdriver, if you estimate that a complete tightening of this point of fixing is necessary. In
theory complete tightening is necessary only in the mobile installations.
Dismount the lower plastic cap of the apparatus giving access to the compartment of wiring.
Carefully fix the apparatus with two screws (Ø 6-8 mm) in the two clamp holes down inside the
compartment of wiring.
If the Xtender is installed in a closed cabinet this must have sufficient ventilation to guarantee an
ambient temperature that conforms to the operation of the Xtender.
**: These items are not delivered with the device.
It is imperative to ensure complete and safe fastening of the device. A device that is simply
hung may detach and cause severe damage.
3.5.3 Fastening of the XTS model
The XTS enclosure must be first mounted on the support plate with
the 4 screws and washer delivered with the appliance according
with figure aside. Then the unit can be fixed on a heavy duty
support (concrete or metallic wall) and positioned vertically with
cable glands oriented down. An external ventilation unit (ECF-01,
p. 37 ) can be installed on top of the unit before or after wall
mounting.
A minimum distance of 20 cm in between and/or around the XTH devices is required in
order to guarantee sufficient ventilation.
The envelope of the XTS can reach temperatures higher
than 60°C when used for a long period near its max
power level. These high temperatures may remain
present during several tens of minutes after stopping the
unit. It’s recommended to choose a place of installation
in a restricted access area, away from children or any
unauthorized person.

3.6 CONNECTIONS
3.6.1 General recommendations
The Xtender falls within protection class I (has a PE connection terminal). It is vital that a protective
earth is connected to the AC-In and/or AC-Out PE terminals. An additional protective earth is
located at the bottom of the unit (See sect 3.6.4 – p. 11/13, tag (17)).
In all cases, the PE conductor for the equipment must at least be connected to the PE for
all equipment in protection class I upstream and downstream of the Xtender (equipotential
bonding). It is mandatory that the legislation in force for the application concerned be
adhered to.
Tighten of the input (13) and output (14) terminals by means of a no. 3 screwdriver (minimum 1.2 Nm
tightening torque) and those for the “Command entry (REMOTE ON/OFF”) (7) and “AUX.CONTAC”
(8) by means of a no. 1 screwdriver (0.55 Nm tightening torque).
The cable cross-sections of these terminals must conform to local regulations.
All connection cables as well as the battery cables must be mounted using cable restraints in order
to avoid any traction on the connection.
Battery cables must also be as short as possible and the cross-section must conform with the
applicable regulations and standards. Sufficiently tighten the clamps on the “battery” inputs (fig. 4a
(11) and (12) (10 Nm tightening torque).
Before connecting or disconnecting the entry or exit cables AC-in (13) and AC-out (14), the
installer must make sure that there is no voltage present in the cables OR on the teminals.
Before connecting the battery, the installer must make sure that the AC-in source and the
AC-out loads are well disconnected.

4 CABLING
The connection of the Xtender inverter / charger is an important step of the installation.
It may only be carried out by qualified personnel and in accordance with the applicable local
regulations and standards. The installation must always comply with these standards.
Pay attention that connections are completely tightened and that each wire is connected at the
right place.
All cables must be insulated. The IEC/EN 62109-1 norm states requires that the cables must be
insulated with PVC, TFE, PTFE, FEP, neoprene or polyimide.
4.1 CHOICE OF SYSTEM
The Xtender may be used in different system types, each of which must meet the standards and
particular requirements associated with the application or site of installation. Only an appropriately
qualified installer can advise you effectively on the applicable standards with regard to the various
systems and the country concerned.
Examples of cabling are presented in appendix I of this manual, fig. 5 and following. Please carefully
read the notes associated with these examples in the tables on p. 33 and following.
4.1.1 Hybrid type stand-alone systems
The Xtender can be used as a primary supply system for off- grid sites where a renewable energy
source (solar, wind or hydraulic) is generally available and a generator is used as backup. In this case,
batteries are generally recharged by a supply source such as solar modules, wind power or small
hydropower systems. These supply sources must have their own voltage and/or current regulation
system and are connected directly to the battery. (Example, fig. 11)
When the energy supply is insufficient, a generator is used as a back-up energy source. This allows
the batteries to be recharged and direct supply to consumers via the Xtender transfer relay.
4.1.2 Grid-connected emergency systems
The Xtender can be used as an emergency system, also known as an uninterruptible power supply
(UPS) – enabling a reliable supply to a site connected to an unreliable network. In the event of an
interruption to the energy supply from the public network, the Xtender, connected to a battery,
substitutes the faulty source and enables a support supply to the users connected downstream. These
will be supplied as long as the energy stored in the battery is sufficient. The battery will quickly be
recharged at the next reconnection to the public grid.
Various application examples are described in figs. 8a – 8c in appendix 1.
4.1.3 Integrated mobile systems
These systems are meant to be temporarily connected to the grid and ensure the supply of the
mobile system when this is disconnected from the grid. The main applications are for boats, service
vehicles and leisure vehicles. In these cases, two separate AC inputs are often required, one
connected to the grid and the other connected to an on-board generator. Switching between two
sources must be carried out using an automatic or manual reversing switch, conforming to the
applicable local regulations. The Xtender has a single AC input.
Various application examples are described in figs. 10a – 10b – 10c.
4.1.4 Multi-unit systems
Whatever system is selected, it is possible to realise systems composed of several units of the same
type and the same power output. Up to three Xtender in parallel or three extenders forming a threephase grid or three times two or three Xtender in parallel forming a three-phase / parallel grid, may
be thus combined.
The use of the Xtender as a UPS must be carried out by qualified personnel who have been
checked by the responsible local authorities. The diagrams in the appendix are given for
information and as a supplement. The applicable local standards and regulations must be
adhered to.
Studer Innotec SA
Xtender
User manual V4.5.0 17
4.1.5 Distributed Minigrid
The implementation of the Xtender on top of a distributed minigrid (beyond the main building)
requires special care in choosing the distribution system.
Studer Innotec recommends a TT distribution for the DC grid as well as for the AC grid.
The size of the grid increases greatly the exposure of the inverters to atmospheric
overvoltage and to non equipotentiality in the grid. This is particularly noticeable in the aerial
distribution grids. In this case very special care must be taken to implement correctly all
protection measures of the installation.
4.2 EARTHING SYSTEM
The Xtender is a protection class I unit, which is intended for cabling in a grid type TT, TN-S or TNC-S.
The earthing of the neutral conductor (E) is carried out at a sole installation point, upstream of the
RCD circuit breaker (D) type A, 30 mA.
The Xtender can be operated with any earthing system. In all cases it is imperative that the protective
earth be connected in compliance with the applicable standards and regulations. The information,
notes, recommendations and diagram mentioned in this manual are subject to local installation
regulations in every case. The installer is responsible for the conformity of the installation with the
applicable local standards.
4.2.1 Mobile installation or installation connected to the grid via plug
connector
When the input of the device is connected directly to the grid via a plug, the length of the cable
must not exceed 2 m and the plug must remain accessible.
In the absence of voltage at the input, the neutral and live are interrupted, thereby guaranteeing
complete isolation and protection of the cabling upstream of the Xtender.
The earthing system downstream of the Xtender is determined by the upstream earthing system when
the grid is present. In the absence of the grid, the earthing system downstream of the inverter is in
isolated mode. The safety of the installation is guaranteed by the equipotential bonding.
The connection (link) between the neutrals (C) upstream and downstream of the Xtender
is not permitted in this configuration.
This connection type guarantees the optimal continuity for supplying the Xtender loads. The first
isolation fault will not lead to an interruption in the supply.
If the installation requires the use of a permanent isolation controller this would have to be deactivated when the TT network is present at the Xtender input.
All sockets and protection class I devices connected downstream of the Xtender must be
properly connected to the earth (earthed socket). The cabling rules above remain valid,
including in installations, in all cases where the Xtender input is connected to the grid via a
plug connector.
The IT system is not recommended for the distribution. This kind of distribution is most of the
time forbidden by the local laws. The achievement of low voltage electric system is always
subject to local laws and must imperatively be implemented and controlled by qualified
and professionally authorized staff. Studer Innotec accepts no liability for damages due to
non-conforming installation and to the lack of compliance with the local rules or with the
recommendations of this manual.
Studer Innotec SA
Xtender
User manual V4.5.0 18
4.2.2 Stationary installation
The installation may be equivalent to a mobile installation (with interrupted neutral).
In a fixed installation where the neutral is connected to the earth at a single installation point
upstream of the Xtender, it is permissible to carry out a connection of the neutrals in order to preserve
an unchanged earthing system downstream, independent of the operating mode of the Xtender.
This choice has the advantage of keeping the protection devices downstream of the Xtender. This
connection can be executed according to the examples in appendix 1, or carried out by modifying
the parameter {1486}.
In this case the appearance of the first fault will lead to the installation stopping or the disconnection
of the protection devices upstream and/or downstream of the Xtender.
Safety is guaranteed by the equipotential bonding and by any RCD circuit-breakers placed
downstream.
This connection (C) is not permitted if a socket is installed upstream of the Xtender.
4.2.3 Installation with automatic PE-neutral switching
In certain applications, it is desirable to keep the neutral upstream and downstream of the Xtender
separated (C) while re-establishing the earthing system (TN-S, TT or TNC-S) in the absence of voltage
at the input. This functionality is forbidden by default by the parameter {1485}. This parameter can
be modified by the parameter {1485} via the RCC-02/-03 remote control. This modification must be
carried out possessing technical knowledge, at the responsibility of the installer and in conformity
with the applicable regulations and standards.
The authorization of this function adheres to the requirements for an earth-neutral connection at the
source.
4.2.4 Lightning protection
As per the installation site, it is highly recommended to set a protection strategy to protect your
installation against lightning. The strategies depend on various parameters directly linked to each site
and we recommend therefore dealing very professionally with this issue.
Damages due to lightning often result in significant costs (full replacing of the printed
electronic board) and are not covered by Studer Innotec’s warranty.
4.3 RECOMMENDATIONS FOR DIMENSIONING THE SYSTEM
4.3.1 Dimensioning the battery
The battery capacity is dimensioned according to the requirements of the user – that is 5 to 10 times
its average daily consumption. The discharge depth of the battery will therefore be limited and the
service life of the battery will be extended.
On the other hand, the Xtender must have a battery capacity that is large enough to be able to
take full advantage of the performance of the equipment. The minimum capacity of the batteries
(expressed in Ah) is generally dimensioned in the following way: five times the rated power output
of the Xtender / the battery voltage. For example, the model XTH 8048 must have a battery of a
minimum capacity of 7000*5/48=730 Ah (C 10). Because of the inverter’s extreme overload capacity,
it is often recommended that this value be rounded up. An under-dimensioned battery may lead to
an accidental and undesired stopping of the Xtender in the event of high instances of use. This
stoppage will be due to a voltage that is insufficient on the battery, subject to a strong discharge
current.
The battery will be selected with regard to the greatest value resulting from the calculations set out
above.
The battery capacity determines the adjustment of the parameter {1137} “battery charge current”.
A value between 0.1 and 0.2 x C batt. [Ah] (C10) enables an optimum charge to be guaranteed.
The methods proposed to dimension the batteries, inverter and generator are strictly
indicative and in no way constitutes a guarantee of perfect dimensioning. The installer is
solely responsible for good dimensioning and installation.
Studer Innotec SA
Xtender
User manual V4.5.0 19
4.3.2 Dimensioning the inverter
The inverter is dimensioned in such a way that the rated power output covers the power of all the
consumers which will be used at the same time. A dimensioning margin of 20 to 30% is recommended
to guarantee that the Xtender will work well in an ambient temperature of more than 25 °C.
4.3.3 Dimensioning the generator
The power output of the generator must be the same or more than the average daily power.
Optimally, it should be two or three times this power. Thanks to the input limit function (see sect. 7.2.2
- p. 27) it is not necessary to over-dimension the generator. Indeed, the loads that are temporarily
higher than the power of the generator will be supplied by the inverter.
Ideally the generator should not have a power output by phase that is less than half of the power of
the Xtender(s) present at this phase.
The power available downstream of the inverter when the generator is working is the same
as the sum of the two powers if the Smart Boost function is activated. The sum of the currents
is limited to a maximum of 57A (80A for the models XTH 8000-48, XTH 6000-48-01 and XTH
5000-24-01). This sum is limited to 20A in XTS model.
4.3.4 Dimensioning the renewable energy sources
In a hybrid system, the alternative energy sources such as the solar generator, wind power and small
hydropower should, in principle, be dimensioned in such a way as to be able to cover the average
daily consumption.
4.4 WIRING DIAGRAMS
Several schematics and wiring comments as in the
diagram to the right are proposed in Annex I of this
manual.
The diagram to the right gives an example of a hybrid
system for a remote site with some renewable energy
sources and single phase generator.
These diagrams are indicative, and in any case the
wiring is subsidiary to compliance with local standards
and practices, under the responsibility of the installer.
Comments regarding the letters / and / or numbers
cited in the diagram aside and of those in the
appendix are given in sect. 16 to 19.
The elements of these diagrams are referenced by a
capital letter when related to the alternating current
(AC) elements.
The elements referenced by a lowercase letter relate
to the direct current elements (DC part of the
diagram.)
4.5 CONNECTING THE BATTERY
The terminals of DC input / output of the apparatus
(11) - (12) p. 9 are intended to be exclusively
connected to a battery, usually of lead acid batteries with gelled or liquid electrolyte
The use of other battery types like Ni-Cd, Li-Ion or other is possible subject to a proper setting of load
profile in accordance with the specifications of the manufacturer of the battery and under the
responsibility of the installer.
Lead batteries are usually available in 2 V, 6 V or 12 V block types. In the majority of cases, in order
The use of the Xtender connected to any other type of DC source without battery (buffer) is
strictly prohibited and may cause significant damage to the device and / or the source.
Studer Innotec SA
Xtender
User manual V4.5.0 20
to obtain an operating voltage that is correct for Xtender usage, several batteries must be
connected in series or in parallel depending on the circumstances.
The various cabling options are presented in figures 5a-5b (12 V), 5c-5e (24 V) and 6a to 6d (48 V) in
appendix I of this manual.
4.5.1 Battery cable cross-section and DC protective devices
The battery cables must also be as short as possible.
It is always preferable to keep the cable at the
negative pole of the battery as short as possible.
In order to avoid any further loss and protection
redundancy, the XTH does not have an internal fuse.
A protective device (f) must be installed as close as
possible to the battery and sized according to the table
on the left.
The recommended cable cross-sections are valid for
lengths less than 3 m. beyond this length it is strongly
recommended to oversize the battery cables.
For safety reasons, we recommend an annual check
on the tightness of all connections.
For mobile installation the connections should be
checked more frequently for tightness.
4.5.2 Connecting the battery
(Xtender side)
Insert the cable glands supplied on the battery cable before tightening the cable lugs. Crimp the
cable lugs and fasten the cable gland on the device. Repeat this for the second battery cable. Fix
the battery cables to the appropriate connections ”+ Battery“ and ”- Battery“. The M8 screws must
be very well tightened.
On the XTM range, you can insert, if required, a fuse directly on the positive connection to the battery
following the procedure below.
Each Xtender is connected directly to the battery through its own protective device (fuse or
circuit breaker. It should never be connected to the output of a DC voltage regulator like
solar regulator, without having the battery as buffer.
All other consumers or sources are connected directly to the battery by their own protective
devices. (See details (f) on Fig. 11-18)
In multi-unit systems, all Xtenders from the same system must be connected according to the
same battery bank.
The battery cables must be protected by one of the following measures in all cases:
- protection device (fuse) at each pole
- protection device (fuse) on the pole not connected to the earth

The cable lugs must be carefully fixed and
tightened sufficiently to guarantee minimum
loss. Insufficient tightening may cause
dangerous heating at the connection point.
The XTS is equipped with an electronic protection device protecting it from accidental
reversal of polarity of the battery. This does not exempt of installing a protective device close
to the battery.
Studer Innotec SA
Xtender
User manual V4.5.0 21
4.5.3 Fuse mounting on battery positive pole (XTM only)
A fuse delivered with the unit (XTM) can be mounted directly on the positive connecting pole to the
battery respecting the below stacking order.
The presence of this fuse does not exempt an installation of a protective device (fuse or circuit
breaker) as close as possible to the battery.
Be careful with the orientation of the ceramic washer. There is a small lip on one side which
must fit into the M10 cable lug’s hole.
4.5.4 Battery-side connection
Before connecting the battery, carefully check the voltage and polarity of the battery using
a voltmeter.
Incorrect polarity or over- voltage may seriously damage the device.
Prepare the batteries for connection: appropriate battery clamps, protection device (f), cable in
good conditions with correctly fitted clamps.
Fasten the negative cable on to the negative pole (-) of the battery and the positive cable on the
open protection device (f).
When connecting the battery, a spark may occur when connecting the second pole. This
spark is normal and due to the load of the internal filtering capacity of the Xtender even if
the unit is halted by the main on off command (1).
The default values of the battery’s charge threshold level are shown in fig. 3a and specified in the
parameter table p.47. If they are not acceptable when compared to the battery manufacturer’s
specification, it is necessary to modify them via the RCC 02/03 remote control before connecting the
voltage sources on the AC input (charger). Studer Innotec is not responsible for default values not
corresponding with the recommendations of the manufacturer.
If the factory settings are modified, the new values must be entered on the parameter table on p. 47
of this manual. The default values proposed by Studer Innotec are the usual values for lead acid
battery or gel batteries (VRLA or AGM).
The cabling and connection of the installation should only be carried out by an appropriately
qualified professional. The installation material such as cables, connectors, distribution boxes, fuses,
etc. must be adapted and must conform to the applicable laws and regulations the application
under consideration.
Regarding the connection of the battery, it is necessary to check that the parameter values
of the Xtender are consistent with the recommendations of the battery manufacturer. Nonconforming values may be dangerous and/or seriously damage the batteries.

4.5.5 Earthing the battery
One of the two battery conductors can be earthed. This may be either the positive or negative pole.
In all cases the installation must conform to the local regulations and usage or specific standards
associated with the application.
In case of earthing, the earthing conductor cross-section must at least be equivalent to the crosssection of the battery conductor. The earthing of the equipment must also adhere to these
regulations. In this case the use of the additional earthing screw is recommended ((17) p. 12/13,
which is located at the front of the device between the two lower fastening screws.
4.5.6 Connecting the consumers at the AC output
High voltages may be present on the connection terminals (13) and (14). Make sure that
the inverter is deactivated and that there is no AC or DC voltage present on the AC-IN
terminals and battery terminals, before proceeding with the connection.
The 230 V consumers must be connected on
the “AC-OUT” (14) connection terminals with
the wire cross-section conforming to the
standards with regard to the rated current at
the Xtender output (see fig. 1a). Distribution
must conform to the local standards and
regulations, and generally, be realised via a
distribution table.
The Xtender terminals are marked in the
following way:
N = neutral, L = live
= protective earth (connected to the
enclosure of the device).
4.5.6.1 Sizing of AC output protective
devices:
If protective devices are installed at the
output, we recommend B curve devices.
They will be sized at maximum to the highest
value listed on the unit’s nameplate at point
(37) (Fig. 1a of the Appendix) or by the
addition of the first value plus the value of the
input protective device. (i.e. inverter current
+ input current).
Cross-sections of downstream wiring must be sized accordingly
If the source assistance function (Smart Boost)(see sect. 7.2.2– p. 27 is not used; the size of the
protection device for the output (F) will be established at a maximum value equal to the rated
current of the inverter, or at the maximum value of the protection device at the input (H) if that one
exceeds the rated current of the inverter.
If the AC input (13) is not used the protective device will be sized equal or smaller than the smaller
value indicated on the nameplate on tag (37)
No downstream protective device is formally required if cross-sections of cable used for
distribution satisfy regulatory requirements for the largest rated output current listed on the
nameplate at the point (37) of Appendix 1a.
Due to the source assistance function (Smart Boost) the current at the output of the device
may be higher than the rated current of the inverter. It is the sum of the current supplied by
the additional source and the current supplied by the inverter. In this case, the dimensioning
of the output cables will be carried out by adding the current indicated on the protection
device (H) located on the upstream of the unit, to the nominal current of the inverter. (See
fig. 1a and chap. 7.2.2.4 – p. 28)

4.5.7 Connecting the AC supply sources
The Xtender is intended to be supplied by alternative voltage sources such as the public grid or a
generator. Check that the rated voltage of the source corresponds to the rated voltage (34) of the
Xtender specified on the nameplate (fig. 1b) tag (34).
The source must be connected to the input terminals marked “AC INPUT” (13) with sufficient wire
cross-section, depending on the power output of the source, and protected by a protection device
of the appropriate calibre. This will be at the maximum 50A for XTH and XTM range and 16A for XTS
appliances.
The terminals are marked in the following way:
N = neutral, L = live
= protective earth (connected to the enclosure of the device).
4.5.8 Wiring auxiliary contacts
These contacts are reversing contacts that are potential-free available in XTH and XTM units. On XTS
models, these auxiliary contacts are available on the external auxiliary relay module (accessory)
ARM-02 (see sect. 9.5 – p. 37). The admissible currents and voltages for these contacts are 16 A: 250
Vac/24Vdc or 3 A: 50 Vdc max. The Contact is shown as activated when the corresponding LED is
lit. The representation of the contact near the terminals corresponds to the status of the contact
when not activated.
The cabling of these auxiliary contracts depends solely on the chosen application and on the specific
programming applied and cannot be described in this manual.
To dedicate/program particular functions to these contacts, please refer to user manual of the
remote control unit RCC-02/03
The factory-set functions for these 2 auxiliary contacts are covered in the sect. 7.5 – p. 31.
Cable-glands that are not in use must be properly closed. If this instruction is not respected,
the equipment loses its degree of protection (IP54) and dust or small animals may enter the
equipment causing significant damage which is not covered by the warranty.
4.5.9 Connecting the communications cables
The Xtenders are equipped with a pair of RJ45/8 connectors that allow information transfer via a
communication bus in between devices or accessories that use the proprietary protocol of Studer
Innotec. In this network all parties in the network are connected in series (chain).
The length of the communication bus cable must not exceed 300 m.
When the Xtender is connected to the remote control RCC-02/-03 or another Xtender compatible
device (VarioTrack, BSP etc.) it is possible that their software versions differ. It is important to harmonize
the software versions of all Xtender compatible products in a system. The update is made by the
remote control RCC-02/-03 from an SD card with a firmware version at least corresponding to the
most recent device.
An additional earthing terminal (17) is present between the two fastening screws at the
bottom of the unit. It can be used instead of a connection on the input terminals of the
device, particularly when cable cross-sections used at the output do not allow the use of a
three-wire cable (live, earth and neutral) through the conduit glands of the connection
cables of the input and output (AC-IN and AC-OUT), or when the earthing of one of the
poles of the battery. PE required using same or greater cross-sections than the battery
cable.
When connecting the device with other compatible devices (Xtender, VarioTrack, BSP,
RCC, Xcom or other) using the same communication bus, it is highly recommended to
make a software update of all components in the system in order to guarantee its
functionalities. Therefore, before starting the setup of the device, download the latest
software version from our website: www.studer-innotec.com on an SD card. Follow the
instructions in the RCC manual for a successful installation.

conducted without stopping the Xtender (hot plug).
The communication bus will be used to interconnect other Xtender inverters in the case of a multiunit application or to connect other types of users who have the proprietary protocol of Studer
Innotec. In these cases, the plug-in of interconnected units is done only after the switch-off of the
installation, by disconnecting the battery or by using the main “ON/OFF” button (1) if present.
The 2 switches for the communication bus termination, “Com. Bus" (4) both remain in
position T (terminated) except when both connectors are in use. In this case, and only in this
case, both must be placed in the O open position. If one of the two connectors is not in use,
the two termination switches (14) will be in position T.
5 XTENDER PARAMETER SETTING
All inverters of the Xtender family have many factory settings and some of them can be modified by
the user or installer. Some basic parameters mentioned in Chapter 7 must be set at the
commissioning. For models XTM and XTH, this setting must be done by connecting the remote control
described in RCC-02/03 chap. 7.3.1 - p. 36. For the model XTS four of them can be done directly into
the unit before powering up.
Many features and associated parameters not described in this manual are described further in the
manual accompanying remote control RCC-02/03 or downloaded from the website www.studerinnotec.com.
When the Xtender is connected to the remote control RCC-02/-03 or another Xtender compatible
device (VarioTrack, BSP etc.) it is possible that their software versions differ. It is important to harmonize
the software versions of all Xtender compatible products in a system. The update is made by the
remote control RCC-02/-03 from an SD card with a firmware version at least corresponding to the
most recent device.
5.1 BASIC PARAMETER SETTING IN THE XTS
For XTS models, the 4 parameters / basic functions below can
be modified directly in the compartment inside the door. All
other parameters can be adjusted, if necessary, via the remote
control RCC-02/03.
• The battery current charge {1138} as described in chap.
7.3.2 - p. 30 by using the potentiometer (16)
• The max. AC source (input limit) {1107} as described in chap.
7.2.2 - p. 27 by using the potentiometer (18)
• The source current assistance (Smart boost) function {1126} as described in chap. 7.2.2.1 - p. 27 by
using the slide button (19)
• The type of detection of AC-input loss (UPS) Fast/Tolerant/slow {1552} as described in chap. 7.2.1-
p. 27 by using the slide button (20)
These manual adjustments can be prevented using parameter {1551} on the remote control RCC02/-03. These values will then be defined by parameters from the remote control. If the parameter
{1551} is set to "yes" the buttons 16, 18, 19 and 20 remain inactive even if the remote control RCC-02/03 and/or the communication module Xcom-232i are removed after the initial setting.
Before opening the enclosure, it is mandatory to
disconnect all AC and DC sources (battery) of the
product to avoid any risk of electrical shock.

6 POWERING UP THE INSTALLATION
It is imperative that the closing cap for the connection compartment (XTM and XTH) and
the XTS enclosure is correctly installed and screwed tight before turning on the power. There
are dangerous voltages within the interior of the connection compartment.
Attention: only a complete tightening of all 4 mounting screws of the XTS enclosure
guarantees the IP 54 protection index.
The Power up of the Xtender must be carried out in the order given below. Any Power off must be
carried out in the reverse order.
6.1 CONNECTING THE BATTERY
6.2 PUTTING THE XTENDER(S) IN OPERATION USING THE MAIN ON/OFF SWITCH (1) IF
PRESENT
The Xtender is supplied and is ready for operation. If you require immediate start-up of the inverter
when the battery is powered up, the main switch (1) must be in the “ON” position and the parameter
{1111} activated. If special configurations or settings are required by the system, it is recommended
to do so immediately according to sect. 5 - p. 24.
6.3 CONNECTING THE CONSUMERS AT THE OUTPUT
Activate the output protection device (F) if existing, and/or press the ON/OFF button (41). The light
indicator “AC-Out” (46) lights up or flashes (in the event of an absence of consumers).
6.4 ACTIVATING THE INPUT CIRCUIT BREAKER(S) (H)
If an AC source (generator or electrical grid) valid in frequency and voltage is present at the AC
input, the device automatically goes into transfer and will start to charge the batteries. The
consumers at the output are therefore supplied directly by the power source present at the input.
Your installation is now in operation.
A too high or inappropriate battery voltage may seriously damage the Xtender. For
example, installing a 24 V battery in the Xtender 3000-12.
If the Xtender XTH or XTM) has been connected the wrong way around by accident
(incorrect polarity of the battery) it is highly likely that the protection fuse on the battery
cable may melt and will have to be replaced. If such is the case, it will be necessary to
disconnect all the connections to the Xtender including the battery. If, after replacing the
fuse, the Xtender proves not to work correctly after reconnecting the battery with the
correct polarity, it will have to be returned to your distributor for repair.
The XTS is electronically protected against reverse polarity. In case of reverse polarity
connection, the unit will remain off. No alarm will signal the fault. It will operate normally
after recovery of the correct polarity.

User manual V4.5.0 26
7 DESCRIPTION OF THE MAIN FUNCTIONS
7.1 INVERTER
The Xtender is equipped with a high-performance inverter which supplies a perfect and very precise
sine wave. Any unit designed for the 230 V/50 Hz electrical grid (or 120V/60Hz for model XTx-xxxx-01)
may connect to it without any problem, up to the rated power out of your Xtender. The inverter is
protected against overloads and short-circuits.
Thanks to the largely over-dimensioned performance level, loads of up to three times greater than
the Xtender’s rated output can be faultlessly supplied for short (3 sec) periods of use, thus allowing
motors to be started up without any problem.
When the Xtender is operating the LED “ON” (43) is glowing.
When the Xtender is in inverter mode, the LED “AC-Out” (46) is glowing. If it flashes, the inverter is in
“load search” mode (see following sect. “Automatic load detection”).
7.1.1 Automatic load detection (load search)
In order to save battery energy, the Xtender inverter stops and automatically goes into load search
mode when the detected load is lower than the sensitivity set by the parameter {1187}. It
automatically goes back into operation when a power consumer greater than this value demands
it. The indicator (46) flashes if the inverter is in “load search” mode, which also indicates that the AC
voltage is present at the output in an intermittent form.
The detection threshold for the absence of loads can be adjusted according to the parameter range
{1187} by means of the RCC-02/-03 remote control. When the parameter is set to 0 the inverter will
still operate even in the absence of any consumer.
In load search mode (standby) the system will thus consume minimal power from the battery (see
table of technical data p. 53).
7.2 TRANSFER RELAY
The Xtender can be connected to an alternative power source such as a generator or public
network. When the voltage at the entry satisfies the voltage {1199 + 1470} and frequency {1505 1506} parameters, the transfer relay will be activated after a delay {1528}. This delay may be adjusted
(extended) to allow a fully stable status of the generator before transfer.
When the transfer relay is activated, the voltage present at the input of the Xtender is available at
the output for the consumers connected. At the same time the battery charger goes into operation.
When the transfer relay of the Xtender is active, the voltage at the output of the Xtender is
equivalent to that which is present at the input and cannot be influenced or improved by
the Xtender. The consumers are supplied by the source present at the “AC-IN” input via the
transfer relay.
The maximum current of the transfer relay is 50 A for XTH and XTM model. It is of 16A in XTS model.
The sharing of energy between consumers and the battery charger is adjusted automatically (see
sect.7.2.2– p.27). The transfer relay will be deactivated when the input voltage no longer satisfies the
parameter {1199} or {1432} min. and max. voltage and frequency at the input or when the current
limit {1107} is exceeded, if the exceeding of this limit is prohibited {1436}. It then passes immediately
into inverter mode. In this case the loads are supplied exclusively by the battery via the inverter (see
sect. 7.2.2.4 – p.28). This switching always takes place automatically.
The presence of increased dynamic loads (such as pneumatic angle grinders, etc.) may lead to an
undesirable opening of the transfer relay due to the weakness of the source. To this case, a delay in
the opening of the transfer relay can be adjusted with the parameter {1198}.
When the generator stops, the change from transfer mode to inverter mode normally takes place
without any interruption of the output voltage. The interruption will be 20 ms in case of input voltage
sudden disappearing when the type of detection of input loss (UPS) {1552} is selected to “tolerant”.
Studer Innotec SA
Xtender
User manual V4.5.0 27
7.2.1 Type of detection of AC input loss (UPS)
When the Xtender is connected to the public grid or to a generator supplying stable and clean AC
voltage, the type of detection of input loss {1552} can be selected to “fast”. In this mode, perturbation
or lack of voltage of less than 1 millisecond can be detected, switching the unit in inverter mode
immediately. This mode guarantees a zero or maximum of 15 ms transfer time.
This mode should not be used in presence of highly disturbed utility grid or with a low power generator
or a generator supplying a poor quality voltage. In that case the parameter {1552} will be set on
“tolerant”. In the XTS model, this can be selected by positioning the UPS slide switch (20) in “off”
position. The tolerance of this mode is adjustable with the parameter {1510} if required.
The ”tolerant” UPS mode insure a interruption time of max. 20 milliseconds.
In rare cases, due to the low quality of the source, and if the transfer relay switches too frequently, it is
possible to further reduce the sensitivity of detection AC input loss by changing the parameter {1552}
to "slow" via remote control RCC-02/03. In this case, the interruption of power will be 40 ms max.
7.2.2 Limiting the AC input current ”Input limit”
7.2.2.1 Principle
In order to best use the resources available at the input (depending on the generator size or the grid
output) and to protect the source from overload, it’s possible to adjust the limit of the input current
with the parameter {1107}.
The Xtender will automatically distribute the available power to the charger and the user and supply
the balance of power if the load demand exceeds the fixed limit thanks to the current assistance
function “smart boost”.
This system proves to be a decisive advantage particularly in all mobile systems (boats, leisure
vehicles and service vehicles) that are frequently connected to sources with a limited value such as
a portable or camping power supply. Despite a limited source, all the greater power applications
downstream of the Xtender remain functional.
Despite a limited source, all loads connected downstream the Xtender remain functional!
The system will reduce automatically the charging current– from its target value {1138} to 0 –
according to the current used at the output and the maximum current available at the input set by
the parameter {1107}. The greater the current at the output, the more the part of the current at the
input assigned to charging the battery is reduced. If the current exceeds the limit {1107}, the Xtender
will supply the balance current from the battery.
The wiring of the system (cable gauge) must take into account this particular function which allow
to have the sum of the current supplied by the inverter plus the current supplied by the source,
I.e. If the system have a 5kW source (22A) and a 5 kW Xtender, the available power at the output is
10kW! In this example, the wire gauge must be chosen for 45A.
7.2.2.2 Exceeding input limit current
If, despite the decrease in current from the charger and using the source current assistance the limit
is exceeded, the transfer relay will remain activated and the source may then be overloaded,
causing the opening of the protective device upstream (H).
Exceeding the limit may be prohibited by the parameter {1436}. In this case, if the current exceeds
the limit {1107}, the transfer relay will open and the user then powered exclusively by the inverter, as
long as the output current exceeds the current limit input. If the input current limit is exceeded due
to a short circuit downstream, the transfer relay will remain activated and the protective device
upstream of the Xtender (H) will trip.
7.2.2.3 Second value of input current limit
A second value of the input limit, to be activated by the command entry (see sect. 7.7 - p. 31), is
programmable by the parameters {1566} (use a different value for the maximum current of the AC
source) and {1567} (second maximum current of the AC source).
If the Xtender is connected to a generator, this must have a power at least equal to half of
the power of the Xtender(s) to which it is connected.
Due to the current assistance feature, the battery can be fully discharged despite the
presence of the grid or the generator! The average power consumed by the user must not
exceed the power of the source, at the risk of discharging the battery.
Studer Innotec SA
Xtender
User manual V4.5.0 28
7.2.2.4 Deactivation of the source assistance function (Smart Boost)
This feature the source current assistance “smart boost” can be disabled by setting {1126}.
The remote RCC-02/03 is necessary to disable the function on the model XTH and XTM. On the XTS
model it is possible to disable it by selecting the slide button (19) in OFF position.
7.2.2.5 Automatic reduction of the current limit input
When the device is connected to a low power generator, most often, the voltage of the generator
falls down before its rated power. To compensate partially this side effect, the Xtender has a system
of automatic reduction of the input current limit, if the voltage drops beyond a threshold set by the
parameter {1309}+ {1433}, to fall to zero when it reaches the value set by parameter {1309}. This avoids
overloading the generator and too frequent transition of the transfer relay.
This feature is also used when a variable power source is connected to the input of the Xtender. This
is particularly the case of 230 Vac alternators type "Dynawatt" coupled to drive motors whose speed
varies. These devices have their source voltage decrease depending on the available power. A
correct setting of thresholds {1309} and {1433} ensures continuous power output with the "Smart Boost"
This feature can be disabled by setting the {1527} especially when the Xtender is connected to a
public network.
7.2.2.6 Setting the current "Input limit"
The maximum input current can be adjusted by the knob (18) on the XTS or via remote control RCC02/03 on other models or on the XTS with the module TCM-01. The parameter {1107} is part of the
basic parameters of the device and must be adjusted at commissioning (see sect. 5 - p. 24)
depending on the capacity of the source as follows:
• If the device is connected to a network: the value is sized according to the upstream protective
device (fuse or circuit breaker) or a lower value if desired.
• If the device connected to a generator, the following empirical formula can be used:
Generator power below 1 kW: 0.7 x Pnom / Uac
Generator power below 3 kW: 0.8 x Pnom / Uac
Generator power above 3 kW: 0.9 x Pnom / Uac
Given the wide divergence of performance and quality of available generators on the market,
these formulas are approximate and are not a guarantee of proper adjustment of the installation.
7.3 BATTERY CHARGER
7.3.1 Working principle
The battery charger for the Xtender is completely automatic and is designed in such a way as to
guarantee an optimum charge for the majority of the lead-acid or gel batteries. Once the transfer
relay is activated, the battery charger goes into operation and the charge indicator (44) lights up.
The charging process is at 3 levels (I/U/Uo) as described in figure below.
This process guarantees optimum charging of the batteries. The charging current is given by the
parameter {1138} and can be adjusted continuously from 0 to the nominal value with the help of the
RCC-02/-03 or with the rotating knob (16) inside the model XTS (see sect. 5.1 – p. 24). All times and
threshold can be adjusted with the remote control unit RCC-02/03.
If the battery voltage is lower than the critical disconnection threshold {1488} operation of
the charger will be automatically prevented. Only the transfer relay is authorised to operate
in this case. The battery must then be recharged by an external source up to a voltage
higher than the critical disconnection threshold in order to allow the Xtender charger to
operate.
In the case of mobile applications the installation of an RCC-02/-03 remote control is
recommended, in order to be able to adapt the value of the input current limit if necessary,
for each connection to a limited grid.

User manual V4.5.0 29
The charge cycle, programmed by
default, as shown in the example
described in the figure opposite,
runs automatically.
The line (28) indicates the
development of the battery
voltage.
The lower line (29) indicates the
battery current (input and output).
The cycle starts with a continuous
current charge (a) adjusted by
default according to the
parameter {1138}. If the ambient
temperature is increased or the
ventilation blocked, the current
may be reduced and become
lower than the selected current.
Once the absorption voltage {1156) is reached, the cycle passes to voltage adjustment mode (d),
known as the absorption phase, the duration of which is set by the parameter {1157}. The minimum
interval between two absorption cycles is limited by the parameter {1161).
At the expiry of the absorption time, or if the absorption current is lower than the parameter {1159},
the voltage is set to a lower value {1140}. This phase (e) is known as the maintenance or “floating”
phase. Due to the limiting function for the input current (see p. 27), it is perfectly normal for the charge
current to be lower than the selected current if the limit of the AC input current {1107} is reached (b).
In this event the AC-IN indicator (45) flashes. The charge current will be limited too if the battery
voltage ripple is higher than 0,5V/cell.
If the “Smart Boost” function is activated {1126} and the power required by the consumer exceeds
the power of the source, the battery will be discharged (c) despite the presence of the grid or the
generator. In this case the LED “charge” (4) goes out. The consumers must ensure that they have
average consumption that is less than the power of the source (generator or public grid) in order to
avoid a complete discharge of the battery. These situations are set out in the figure below.
If the BTS-01 temperature sensor is used, the voltage adjustment thresholds for the battery are
corrected in real time by means of the battery temperature. The value of this correction is set by the
parameter {1139} in the parameter table p. 47.
Much more complex charge profiles or exclusion of the charger can be configured using
the RCC-03/03 remote control.

7.3.2 Battery charger current setting
The maximum charging current can be adjusted by the knob (16) on the XTS or via remote control
RCC-02/03 on the other models or on the XTS with the module TCM-01. The parameter {1138} is part
of the basic parameters of the device and must be adjusted at commissioning (see chap. 5 - p. 24)
depending on battery capacity. It will be chosen in principle a value between 0.1 and 0.2 x the
nominal battery capacity C10. (I.e. 10A for a battery of 100 Ah/C10)
7.3.3 Battery protection
The battery is protected against deep discharge by stopping the inverter if the low voltage
disconnection level {1108} is reached. The indicator (52) flashes once when the battery has reached
the disconnection threshold and the inverter will stop shortly after {1190}. This threshold can be
dynamically corrected {1191} with an advanced algorithm that computes automatically the battery
voltage compensation in function of the instantaneous power. This correction may also be manually
fixed {1532} by setting the low voltage disconnection at full load {1109}. These dynamic corrections
can be deactivated by setting the parameter {1191}. The inverter will stop immediately if a critically
voltage of 1.5V/cell is reached. The inverter will restart automatically when the battery voltage has
reached the restarting threshold {1110}.
This restarting threshold {1110} can be automatically readjusted if the parameter {1194} is activated,
in order to better protect the battery against repeated cycling in an "almost empty" state of charge.
The restarting threshold is then incremented {1298} up to a maximum value {1195} whenever the LVD
(low voltage disconnection) is reached. The restarting threshold will be reset to its initial value when
the value of parameter {1307} is reached.
If the inverter is repeatedly {1304} encountering a low voltage disconnection in a short period {1404}
it will stop permanently and will only start again via an operator’s manual restart.
7.4 XTENDER PROTECTION
The Xtender is protected electronically against overloads, short-circuit, overheating and reverse
current (cabling of a voltage source on AC-Out).
7.4.1 Protection in case of overload
In the event of overload or short-circuit at the output, the inverter stops for some seconds {1533}
{1400}, and restarts. If the inverter is repeatedly encountering this situation {1300} in a short period, it
will stop permanently and will only start again via an operator’s manual control.
7.4.2 Protection against overvoltage
If the battery voltage exceeds the value set by the parameter {1121} the inverter stops and starts up
again when the voltage is less than {1110}. If the Xtender is repeatedly encountering this situation 3
times during one minute, it will stop permanently and will only start up again via an operator’s manual
control.
A battery voltage greater than 1.66 x the nominal voltage may lead to significant damage
or destroy the device.
7.4.3 Protection against overheating
Insufficient ventilation, increased ambient temperature or obstructed ventilation may lead to
overheating of certain internal components of the unit. In this case, the device will automatically limit
its power output as long as this abnormal situation persists.
Parameters of the battery charger are under the responsibility of the operator. Incorrect
parameter that does not correspond to the charging methods of the battery
recommended by the manufacturer may be dangerous and/or considerably diminish the
battery service life. If the factory settings are modified, it is imperative that the new values
be entered in the parameter table p. 47.
Studer Innotec SA
Xtender
User manual V4.5.0 31
7.4.4 Protection against battery reverse polarity
The Xtender is protected from reverse polarity by means of an external fuse installed on the battery.
7.5 AUXILIARY CONTACTS
The XTH, XTM and XTS, the latter when equipped with the ARM-02 module, have two dry reversing
contacts that are potential-free. The status of the contacts in deactivated mode is indicated by the
annotations, N.C. = normally closed and N.O. = normally open. When the contact is activated an
indicator light (9) is illuminated. (Maximum contact loads: 230 Vac / 24 Vdc: 16 A or: max. 50Vdc/
3A) The behaviour of these contacts can be programmed using the various parameters described
in the remote control RCC-02/-03 user manual and it can be modified by the user/installer.
The behaviour of these contacts can be programmed using the various parameters described in the
remote control RCC-02/-03 user manual and it can be modified by the user/installer.
These dry contacts are programmed by default for the following functions:
Contact no. 1 (AUX 1): The contact has a function of automatic start of generator (two wires). The
contact will be activated when the battery voltage is below a value, during a given time fixed by
parameters {1247/48}/{1250/51}/{1253/54}. The contact will be deactivated when the charge cycle
has reached floating {1516}, or when the "Aux. 1 deactivation voltage" {1255} is reached during a
predetermined time {1256}.
The voltage of the battery is automatically compensated according to the instantaneous
battery current the same way as it is done for compensation of LVD (see sect. 7.3.3– p.30) if
parameter {1191} is activated.
Contact no. 2 (AUX 2): alarm contact by default. It is deactivated when the inverter is out of service
or is working at reduced performance, either because of manual control or if there is an operational
fault such as overload, under-voltage of the battery, over-temperature, etc.
If the operator or installer requires different behaviour for the auxiliary contacts, they are both freely
and individually programmable depending on the battery voltage, the output power, the inverter
status, the internal clock and the Battery state of charge (if BSP module is present) . These settings
can be done with the RCC-02/-03 (remote control unit).
The intelligent programming of the auxiliary contacts allows many applications to be considered
such as:
Automatic start-up of the generator (two or three wires)
Automatic load shedding of lower priority loads of the inverter (2 sequences)
Global or individual alarm
Automatic disconnection (load shedding) of the source
For more information on the programming of auxiliary contacts 1 and 2, refer to our
application notes available on the Studer web site: www.studer-innotec.com:
AN003: Anti-blackout system for grid connected application (Solsafe)
AN005: Automatic management of 2 different energy sources
AN007: Automatic start of a generator
7.6 THE REAL TIME CLOCK
The Xtender (see sect. 9.4 – p. 37) has a real time clock that allows programing the function of the
auxiliary contacts according to time schedule. This clock must be adjusted via the use of the RCC02/-03 remote control.
The XTS is equipped with a full electronic protection device protecting it from accidental
reversal of polarity of the battery. This does not eliminate the need to install a fuse close to
the battery. In case of reverse polarity, the fuse will not be destroyed and the unit will operate
normally after restoring the correct battery polarity.

7.7 ENTRY COMMAND (REMOTE CONTROL ON/OFF)
This function and associated terminal block (7) is
available as a standard on XTH series. It is available
for the XTM and XTS series by using the external
RCM-10 module (optional accessory). See sect. 9.3
- p. 36.
This entry can be used to drive one or more
function that you can choose thru programming
with the RCC-02/-03.
There is no dedicated function from factory. In
multi-unit configuration (see below) the chosen
functionality must be the same in every unit in the system. Only one unit can be wired to apply the
function to every Xtender in the system. If the entry command is used as an emergency stop, (all
functions halted), it has to be wired on the unit with the highest serial number (master) of phase one.
The function is activated by opening /closing a potential free contact, or by applying a voltage on
the entry.
On XTH model, the wiring is done across the entry terminal block (7). The jumpers (6) must be correctly
positioned according to the chosen variant as described in the following figure.
Driven by a dry contact: the jumpers
are left in original factory setting A1-2
and B2-3
Driven by a voltage (Max. 60 V
eff./30mA): the jumper are
positioned A+-B1 and A2-B2
On XTM and XTS the wiring of this
entry is done on the RCM-10 plug
(15) according to the wiring example
on the right.
If this function is used in the mode active when contact is open (such as the emergency
stop, for example), the unused remote entries (in the other units) should be bridged
(equivalent to closed contact). The dedicated functionality will then be activated when the
drive contact opens which is connected to one of the units.

8 MULTI-UNIT CONFIGURATION
Several Xtenders can be used in the same system, either to create a three-phase system or to
increase the power output of a single or two phases. The implementation of this configuration requires
particular precautions and it must be installed and commissioned by qualified personal only.
When a multi-unit system is commissioned, the software version of every unit will be
automatically checked and units may refuse to start in case of incompatibility. If so, an
upgrade of every unit is required with the RCC-02/-03 to the most recent software version
available by the manufacturer. (Read the RCC-02 user's manual to perform this operation).
In Multi-units system every Xtender in the system shares the same battery bank.
Separate battery bank are no allowed.
In these multi-unit systems, the units must be connected via a communication bus by a cable (art.
no. CAB-RJ45-8-2) of a maximum length of 5 metres.
Various application examples are described from fig. 12 to fig. 19 of Appendix 1.
It is important to read and adhere to the descriptions associated with each of the figures
mentioned above.
In multi-unit system, it is recommended to use the automatic LVD dynamic compensation.
See parameter {1532}.
In configuration with several Xtenders, each unit is controlled independently using the ON/OFF push
button (41). When the on/off control is given via the RCC-02/-03 remote control, it is applied
simultaneously to all units.

Three Xtenders of the same voltage (power or type can be different) can be used and combined in
order to establish a three-phase grid. An example of cabling in three-phase is given at figs. 13.-14 of
the appendix.
When 3 Xtenders are wired to form a three-phase grid, the wired phases at the input determine the
jumper position for selecting the phase (10). It is vital to determine and select the phase for each
Xtender. If the grid is not available at the input of the master unit (phase 1), all the units of the system
will switch to inverter mode. If only a single-phase source is available, it must be connected to phase
1. The other two phases will therefore be supplied by the other two working units in inverter mode.
8.2 INCREASING THE POWER BY PARALLELING UNITS
Up to three Xtenders of same type - power and voltage- can be wired in parallel in order to increase
the system’s rated power output. In this configuration, all the AC-in inputs of the Xtender must be
wired. The most recent unit (according to the serial number) in the phase will act as the master and
will decide on the operation or suspension of the units in parallel according to the load. The yield of
the installation is therefore still optimal.
It is possible to deactivate the master/slave mode with the parameter {1547}. In that case, the load
search mode is disabled.
An example of parallel connection is given in fig.12 Appendix 1 and the comments on p.42.
If the current of the source (per phase) is greater than 50A (XTH and XTM) or 16A (XTS), a
protection device must be installed on each of the 2 or 3 devices connected to the same
phase with 50A max (XTH and XTM) or 16A (XTS). If the power source is limited to 50A (XTH
and XTM) or 16A (XTS), only one protection device is enough.

8.3 COMBINED SYSTEM
It is possible to combine a three-phase system with 1 or 2 phases made up of 2 or 3 Xtenders in
parallel. An example of cabling is given in fig. 15.
A combination of more than one inverter in only one (or two) phases is also possible. for example, it’s
possible to build up one powerful phase for the most single phase consumer and the 2 other phases with
only one Xtender each for the 3 phase (motor) application as in the example fig. 15 Appendix I.
It is therefore possible to combine up to nine Xtenders by running three Xtenders in parallel in a threephase grid. Examples of cabling are given in figs. 16 to 18 Appendix 1 and the comments on p. 42.
8.4 ENLARGEMENT OF AN EXISTING INSTALLATION
Only subject to compatibility, it is most of the time possible to enlarge an existing installation by
adding one or several inverters in parallel or in a three phase configuration. The compatibility of the
new units must be checked by providing Studer Innotec the serial numbers of the inverters in the
existing installation.
The inverters connected to the same system must be equipped with the same software
version. Take care to download the latest software version from manufacturer’s website
and update all units of the system before the commissioning.

11 CONTROL
11.1 MAIN ON/OFF CONTROL
This switch (1) interrupts the electronic supply and
all the Xtender peripherals. The residual
consumption on the battery is therefore less than
1 mA.
The ON/OFF switch is used only for the complete
stoppage of the whole system. This switch is not
available in the XTM. The function can be added
with the use of the remote command module
RCM-10.
11.2 DISPLAY AND CONTROL PANEL
The Xtender has an ON/OFF button and light
indicators at the front of the unit, allowing clear
identification of the operating mode.
(41) The ON/OFF button allows the start-up or
complete stop of the system. In the systems
comprising several units, each unit is started or
stopped individually. For a simultaneous start-up of all
the units use the dry contact control (see sect. 7.7 –
p. 32) or the ON/OFF button of the RCC-02/-03
remote control.
Even when the equipment has stopped,
dangerous voltages may be present at the
Xtender input.
(42) This indicator lights up when the equipment has been stopped manually using the ON/OFF
button (41) or due to a fault.

(Imminent) stoppage due
to a too low battery
voltage.
If the inverter has not yet stopped, it is recommended to
disconnect all non-priority loads and/or start up the generator. If
the inverter has stopped it will restart automatically when the
battery voltage has reached the correct value again {1110}. It
can be restarted manually using the ON/OFF button (41) as long
as the battery voltage is higher than 1,5V/cell. The charger
remains functional as long as the battery voltage remains higher
than 1,5V/cell. See also sect. 7.4 – p. 30.
2x
Stoppage due to
overload in the
equipment, due to either
a short-circuit or too high
load for the inverter.
In this event the equipment will attempt to restart 3 times within a
few seconds and will stop if the overload remains (see sect. 7.4.1
– p. 30). It is vital to eliminate the cause of the overload before
restarting. Restarting is carried out manually by pressing the
button (41).
3x
Decrease in the rated
output of the device due
to a too high internal
temperature.
This may be due to overload of the device, too high ambient
temperature or obstructed ventilation. The power output of the
device will therefore be limited to around 50% of the Pnom,
including in charger mode or Smart Boost mode.
4x

power from the source
In this case, the Xtender remains in operation in inverter mode
until the output power decrease below the input limit and does
not allow the transfer relay to close. You must increase the input
current limit {1107}, authorise exceeding this limit {1436}, authorise
backup on the source {1126}, or disconnect some consumers
(decrease of loads).

If the Smart Boost mode has been activated, this indicator stops blinking temporarily when source
backup is required by users (loads).
(45) This indicator is lit continuously when an alternative voltage with correct values, either in
frequency {1112-1505-1506} or in voltage {1199}, is present at the AC input of the device and the
current limit set by the user has not been reached.
It flashes one time when the current limit at the input {1107} set by the user has been reached. In this
case the charger current is reduced in order to guarantee priority supply to the users (see sect. 7.2.2.2
- p. 27).
If the Smart Boost mode (see sect. 7.2.2.4 – p. 28) is used and the inverter is part of the user supply –
therefore the battery is discharged – the “charge” indicator (44) will be glowing.
If the input current is exceeded nevertheless, and this exceed not permitted by parameter{1436}, the
Xtender goes back to inverter mode (transfer relay open) and the indicator (42) will keep flashing as
long as the user current exceeds the limit value of the input current {1107}.
If grid feeding is allowed {1127} this indicator blinks 2 times while feeding.
(46) This indicator is lit continuously when an alternative voltage of 230V is present at the equipment

Installation example in a boat, with isolation transformer
Characteristic: With several power sources, like shore connection and on-board generator,
a switchover (X) must be installed, to safely switch between the different voltage sources with
guaranteed interruption of the phase and neutral conductors. Moreover, an earth must be
formed (E) after the isolation transformer.
11
Example of a hybrid installation
This is the most common system used to establish an emergency system or a hybrid system
(grid-remote sites) ensuring a single-phase supply from a generator and/or the battery.
Highlight(s): In a hybrid installation, the sources for recharging a battery (k-m) are connected
directly to the batterie via their own regulator and their own protective device. This does not
interfere with the Xtender charger.
12
Example of parallel connection of 2 or 3 Xtenders
1. Only Xtenders of the same power output may be connected in parallel.
2. Wiring precautions: The cable lengths and cross-sections of AC-In input (A) and AC-Out
output (B) must be the same for all inverters in parallel in the same phase.
3. Variant: The sum of the lengths of the cables (A1) + (B1) of Xtender 1 must be the same as
the sum of the lengths of the cables (A1) + (B1) of Xtender 2, and for Xtender 3
4. The AC input for each Xtender must be protected individually by a protection device (H)
of the appropriate size but max. 50A (XTH and XTM) or 16A (XTS).
5. The protection device at the output of the Xtender (F) can be shared and should be sized
given the sum of the currents of the devices in parallel.
6. In a multi-unit system, the functionality dedicated to the command entry (sect. 0 - p. 31)
must be the same for every unit. Only 1 unit has to be wired and the function is applied to
every unit of the system.
13
Example of three-phase cabling of 3 Xtenders – three-phase input
Highlight(s): When 3 Xtenders are wired to form a three-phase grid, the wired phases at the
input determine the jumper position for selecting the phase (10). It is vital to determine and
select the phase for each Xtender.
See also sect. 8.1 – p. 33.
The comments for fig. 12 - 4 to 6 are valid.
14
Example of three-phase cabling of 3 Xtenders – single-phase input
Highlight(s): In a three-phase configuration, if only one phase is available as a source, only
one Xtender will be wired on that source. Phase 2 and 3 will be permanently fed from the
two other units connected only to the battery (not connected to ACin).
It is vital to determine and select the phase for each Xtender.
The comments for fig. 12 are valid.
15
Example of three-phase, input and output wired, with reinforced phase
Highlight(s): This installation allows a three-phase supply with a reinforced phase The
reinforced phase may be incorporated on two or even three inverters in parallel. The
protection device at the output on which 2 or 3 Xtenders are wired must be calibrated
according to the sum of the maximum currents of the devices in parallel.
The comments for fig. 12 to 13 are valid.

Description
Comment
A
Input supply
cable
The cross-section is defined by means of the maximum current at source and
the protection device (H). In multi-unit systems, cables (A) of the same phase
must have the same length and cross-section (see comment fig. 12-2/3).
B
Output
supply cable
In multi-unit systems, cables (B) of the same phase must have the same length
and cross-section (see comment fig. 12-2/3). The cross-section must be selected
by means of the Xtender’s output current given on the type plate and the
protection device selected for the input (see fig. 1a).
C
Connection
of the
neutrals
See sect. 4.2 - p. 17.
In a fixed installation where the neutral is connected to the earth at a single
installation point upstream of the Xtender, it is permissible to carry out a
connection of the neutrals in order to preserve an unchanged earthing system
downstream, independent of the operating mode of the Xtender. This presents
the advantage that the downstream protecting ground fault devices remain
functional.
This connection (C) is not permitted if a socket is installed upstream of the
Xtender.
D
Differential
circuit
breaker
A protection device can be installed downstream of the source (G or U)
according to the local requirements and in compliance with the applicable
regulations and standards.
E
Earth-neutral
connection
bridge
The neutral is earthed at a single point of the installation, downstream of the
source and upstream of the protection device(s) at the default current (DDR).
When several sources are available, each source must have an earthed
neutral. If the source has to be retained with an isolated earthling system (IT) the
applicable local provisions and regulations must be applied.
F
AC output
protection
devices for
the Xtender
A protection device dimensioned depending on the cable cross-section used
may be installed downstream of the Xtender (main circuit breaker before
distribution). The cable cross-section is to be dimensioned according to the
calculation table of maximum output current (fig. 1). The internal current
limitation value of the Xtender is stated on the type plate Fig. 1b (35).
G
Generator
The generator is dimensioned according to the requirements of the user. Its
rated current will determine the adjustment of the parameter {1107} “maximum
current of the AC source”.
H
Protection
devices at
the Xtender
input
The protection device at the input of the Xtender must be dimensioned
according to the power output of the source at the cable cross-section used. It
will not exceed a calibre equivalent to the input current “I AC-In” given on the
type plate of the unit Fig. 1b (35).
K
Connection
plug / socket
If the Xtender is connected to an AC source by means of a plug, the
connection cable must not exceed a length of 2 m, and the socket must
remain permanently accessible. The socket will be protected by a protection
device of appropriate calibre. The connection of the neutrals (C) is prohibited
in this case.
S
Secured grid
Distribution to the users supplied by the grid or the generator when this is present
or by the Xtender within the limit of its power output from energy stored in the
battery. This distribution is carried out in conformity with the local standards and
regulations.
T
Non-secured
grid
Distribution to users supplied exclusively via the present grid or the generator.
This distribution is carried out in conformity with the local standards and
regulations.
U
Public grid
The connection to the public grid imposes adherence to the local standards
and regulations at the responsibility of the installer. The installation should, in
principle, be checked and approved by an official body.

V
Automatic
earth-neutral
connection
This connection is deactivated by default. In may be used in certain specific
cases for automatically re-establishing the neutral system type TT (TNC, TNS,
TNC-S) when the Xtender is in inverter mode. The activation is carried out via
RCC-02/-03 remote control by configuration of the parameter {1485}. This
operation may only be carried out by qualified personnel, under the
responsibility of these personnel, and in conformity with the local standards
and regulations. See 4.2.3 – p. 18.
W
Galvanic
isolator
This device (optional) is generally used to reduce the risk of electrolytic
corrosion due to the direct current when a boat is connected at the dock.
X
Source
reversing
switch
When the installation has more than one supply source, it is necessary to
install a switching device between the sources, simultaneously switching the
neutral and the phase(s) of these sources. In all cases this device (manual or
automatic) must guarantee interruption of the connected source before its
connection to another source.
Y
Isolation
transformer
This device (optional) prevents the risk of galvanic corrosion due to direct
currents when a boat is connected at the dock.
