General Description
2.1 Reliability and Quality Standards
Congratulations on your purchase of the MINIpowerPLUS UPS.
The MINIpowerPLUS UPS incorporates the latest technological advances in power engineering to offer a
highly reliable, upgradeable UPS system with excellent electrical performance and low running costs.
Uninterruptible Power Supplies Ltd. are leading specialists in the provision, installation and maintenance of
UPS systems; and this compact and powerful UPS is just one example of our wide range of state-of-the-art
power protection devices able to provide your critical equipment with a reliable power supply for many years.
The criteria and methods used in the design, manufacture and maintenance of this UPS system are certified
to International Standard ISO 9001/EN 29001 and ISO 14001.
A full equipment specification is provided in Chapter 8 of this manual.
2.2 MINIpowerPLUS Model Range
The MINIpowerPLUS system is available in two model ranges.
MINIpowerPLUS 5000
The MINIpowerPLUS 5000 is available in both Rackmounted and Tower versions and uses up to four
1250VA power modules to offer a system output rating
of 1250VA, 2500VA, 3750VA or 5000VA.
Each power module requires three batteries which are
housed within the UPS cabinet to provide a completely
self-contained UPS system.
An optional external battery cabinet can be connected
to the UPS to extend the system’s autonomy time if
required.
MINIpowerPLUS 10000
MINIpowerPLUS 10000 uses between four and eight
1250VA power modules to offer a system output of
5000VA, 6250VA, 7500VA, 8750VA or 10000VA.
In this model range the batteries are contained in a
separate battery cabinet which is similar in design and
appearance to the UPS cabinet and is usually
positioned adjacent to the UPS cabinet to form a
matching suite.
If required, additional battery cabinets can be
connected to the existing battery cabinet to extend the
system’s autonomy time.

Figure 2.3 MINIpowerPLUS Power module usage
If a system is purchased without the maximum number of power modules fitted, additional modules may be
fitted in the field (up to the limit of 4/8 modules) to expand the system up to full capacity; however this
requires the UPS to be shut down while the additional module(s) and batteries are fitted.
2.3 Operating Principles
The UPS has three main operating modes:
• Mains operation
• Battery operation
• Bypass operation
Mains operation
When the mains supply is present, the input voltage is filtered then rectified by the power factor correction
stage. This optimises the use of the mains supply by making the power factor practically unity, and
compensates for any input voltage fluctuations. The rectified output from the power factor correction stage i s
connected to the inverter where it is converted to a clean, sinusoidal output voltage with very low distortion.
The operation of the power factor correction stage is particularly important when operating with very low
loads. For example, with a nominal load of around 50% it is possible to sustain the inverter operation with the
input mains voltage as low as about 100V without reverting to battery power. This feature enables a more
intelligent management of the switchover to battery power and minimises battery use. During mains
operation the battery is continuously charged by a dedicated battery charger circuit.

2: General Description
Figure 2.4 MINIpowerPLUS block diagram
A rapid, synchronised by-pass circuit is used to assist during overloads that exceed the inverter’ s capacity –
for example when certain peripherals that require a high start current are initially switched on.
The UPS power circuitry is a ‘passing neutral’ type: i.e. the mains supply neutral is common through to the
inverter output. During normal operation, a sensor monitors the potential between the neutral wire and the
earth wire and if it becomes excessive it:
• activates the input protection circuitry, which turns off the power factor correction stage
• switches the UPS to battery operation
• signals an error on the UPS control panel
Note: If preferred, the control software can be configured so that only an error signal is produced, without a
switchover to battery operation.
All the UPS operating functions are supervised in real-time by a microprocessor which co ntrols and stores
certain operating parameters in addition to managing an RS232 computer interface.
Battery operation
If the mains voltage fails, or is subject to excessive sag, the voltage booste r stage activates automati cally to
provide an additional (or alternative) d.c. supply to the inverter. When this occurs the inverter input power
source transfers seamlessly between the power factor correction stage and the voltage booster, and the
inverter maintains the load supply without any power interruption.

The voltage booster stage obtains its power from the batteries, and when the UPS operates in this mode the
operator is informed that the battery is ‘on load’ and th erefor e discha rging, and a number of alarms activate at
preset voltage levels as the battery discharges. The operating threshold and function of these battery alarms
can be set by the operator through the UPS Setup menu to suit local application requirements.
Bypass operation
When operating in the bypass mode the bypass circuit totally excludes the UPS and connects the UPS input
supply directly to the UPS output.
The UPS automatically switches to bypass operation if:
• the UPS develops a fault which renders it unable to sustain the UPS output supply
• the UPS is shutdown for maintenance or repair purposes
• (momentarily) to assist the UPS handle an overload condition that exceeds the inverter rating
During normal operation the inverter is synchronised to the incoming mains supply so that when a transfer to
the bypass mode is required it takes place in a synchronised manner to prevent the risk of a power break or
excessive voltage.
A dedicated bypass configuration menu provides a mean s of customising the by-pass circuit operatio n to
meet specific application demands. T his feature pr ovides many opti ons such as: ‘aut omatic’, ‘dis abled’, ‘by pass in load waiting’ mode, etc.
2.4 Warranty
The MINIpowerPLUS is supplied with a limited warranty that the UPS and its component parts are free from
material and manufacturing defects for a period of one year from the date of original commissioning or fifteen

Installation
3.1 Introduction
This chapter contains all the information necessary to enable you to correctly install the MINIpowerPLUS
UPS, including unpacking, storage, positioning and cabling instructions.
Commissioning options
If the UPS is delivered with the batteries already fitted and connected, the system can be considered as
being ‘plug and play’ and can be installed and powered ON by the user. However, if it is delivered without the
batteries fitted, the cabinet(s) can be installed by the user but the batteries must be fitted and commissioned
by an Uninterruptible Power Supplies Ltd. approved engineer.
Note: The MINIpowerPLUS 5000 rack-mounted UPS is always shipped with the batteries fitted and
connected.
3.1.1 Receipt of the UPS
The UPS equipment, which includes the UPS Cabinet, batteries and accessories, are delivered on pallets
that can be moved easily with the aid of a pallet jack. Before you accept receipt of the equipment ensure that
the shipment is complete and the package(s) match the description shown on the delivery note.
The UPS Cabinet is packed in a container designed to protect it from mechanical and environmental damage
during transit. This protection is enhanced by wrapping and sealing the container in a polythene sheet.
Upon delivery you should carefully examine the packing containers for signs of physical damage. If there are
signs of transportation damage you must inform both the carrier and Uninterruptible Power Supplies Ltd.
immediately.
WARNING: The electrical installation of this UPS system and its peripheral equipment must be
carried out by an authorised electrician or other suitably qualified personnel.
Uninterruptible Power Supplies Ltd. will take no responsibility for any personal injury or material
damage caused by incorrect handling, cabling, operation, or other activities that are not carried out
fully in accordance with the instructions contained in this manual.
WARNING: If the UPS is purchased and supplied without batteries, Uninterruptible Power
Supplies Ltd. will not accept responsibility for any UPS damage or malfunction caused by the
incorrect supply, storage, installation or connection of batteries by third parties.
CAUTION: When off loading the UPS equipment always keep it in an upright position.
Do not drop the equipment or stack the pallets.
Key Point: Claims for shipping damage that is discovered later when unpacking the equipment
must be filed immediately when found. All damage claims must be reported to the carrier within
seven days of receipt of the equipment.
If any shipping damage is discovered you should store all affected packaging materials for further
investigation.
WARNING: Do not attempt to install or power-up damaged equipment.

3-2 UPS453-01-00 MINIpowerPLUS User Manual Dated 08-03-12
3.1.2 Site transportation
When locally transporting the UPS equipment after it has been off loaded please observe the following
cautions:
3.1.3 Unpacking the UPS
Note: Do not unpack the equipment if you intend to put it into storage prior to use (See paragraph 3.1.5).
Castors are fitted to the UPS Tower cabinet to enable it to be wheeled into position once it is unpacked.
Before you remove a UPS Tower cabinet from its shipping pallet you should ensure that the floor surface is
level and suitable for wheeling the cabinet into its final position. You should also ensure that the floor material
can safely support the weight of the UPS equipment and batteries.
1. Remove any external polythene sheeting.
2. Remove the cardboard packing container:
Carefully cut through the securing bands then pull the container upwards.
3. Remove the protective polythene covering and any other packing from around the UPS cabinet.
4. Remove the fixings screws that secure the UPS feet to the pallet base, then carefully remove the UPS
from the pallet.
5. Retain the packaging materials for future shipment of the UPS.
6. Examine the UPS for signs of damage and notify your carrier or supplier immediately if any damage is
apparent.
3.1.4 Batteries
The UPS uses sealed, maintenance-free batteries mounted on shelves within the UPS cabinet or housed in
an external battery cabinet. Normally, the system is shipped with the batteries already installed and
connected. If the batteries are ordered and sh ipped separately they must b e fitted by a manufacturerapproved engineer as part of the system commissioning procedure.
3.1.5 Storage
UPS Cabinet storage
If you plan to store the UPS cabinet prior to installation it should be kept in a clean, dry environment with an
ambient temperature between +5°C to +40°C and relative humidity of less than 90%.
Ideally the UPS cabinet should be stored in its original shipping packaging, but if it is removed from its
packing container you must take measures to ensure it is protected from dust and humidity.
Battery storage
If shipped separately, the batteries should be stored in a dry, clean, cool environment and preferably in thei r
original packaging. If the packaging is removed, the batteries must be protected from dust and humidity.
When stored, all batteries will self-discharge at a rate that is greatly affected by the ambient temperature.
Batteries should therefore be fully charged before being put into storage and if they are to be stored for a long
CAUTION: If dropped, the weight of the UPS cabinet could cause serious injury to personnel or
damage equipment in the surrounding area. Always handle with care.
If the equipment is accidentally dropped do not connect it to the mains electricity suppl y.
Key Point: Before proceeding further with the installation process, check that the technical
specifications on the nameplate located on the UPS back panel matches the purchased material
detailed in the goods delivery note.
Key Point: If the batteries are shipped separately, where possible it is preferable to leave them in
their packaging until they are required for commissioning (see below for storage information).
UPS453-01-00 MINIpowerPLUS User Manual Dated 08-03-12 3-3
3: Installation
period they should be recharged periodically to prevent them from losing their original capacity. As a guide,
the batteries should not be stored for longer than the periods shown below without being recharged:
• 6 months at 20°C
• 3 months at 30°C
• 2 months at 35°C
3.2 Planning the Installation
A certain amount of pre-planning will help ensure smooth, trouble-free installation. The following guidelines
should be considered when planning a suitable UPS location and environment.
3.2.1 MINIpowerPLUS Tower versions
Cabinet positioning and accessibility
The MINIpowerPLUS 5000/10000 UPS Tower
cabinet is compact and mounted on wheeled
castors so that it can be easily moved to its
intended operating location.
As shown in Figure 3.1 the UPS and battery
cabinets require a minimum of 200 mm
clearance at the rear and either side to permit
adequate cooling airflow. However, in each case
full rear access is required for cabling, and side
access is necessary for maintenance and repair.
For this reason it is recommended that the
cabinets are located so that they can be
wheeled forward to provide the necessary side
and rear access when required.
This recommendation must be taken into
consideration when cabling the equipment so
that a sufficient cable length is provided to allow
for the prescribed cabinet movement.
Figure 3.1 shows a space of 900 mm provided at
the front of the cabinets. This allows adequate
room for the safe passage of personnel during
normal operation and also sufficient space for
the cabinets to be pulled forward for access, as
described above.
Note: Ensure that the cabinet is located in an
area where the ventilation grills are unlikely to be
accidentally covered.
Moving the UPS to is final location
• The flooring material where the UPS is to be located should be non-flammable and capable of safely
supporting the weight of the UPS cabinet and battery cabinet (where used).
• The transit route must allow the equipment to be transported in an upright position.
CAUTION: Sealed batteries must never be stored in a discharged or partially discharged state. The
batteries can be destroyed by extreme temperature, under-charge, overcharge or over-discharge!

3.2.2 MINIpowerPLUS Rack-mounted versions
Rack positioning and accessibility
The MINIpowerPLUS Rack-mounted UPS cabinet
is designed to fit into a standard 19 inch rack and
is 6U high. The cabinet is fitted through the front
of the rack, supported on suitable rails and
secured in position by means of two screws on
each side of the front of the assembly.
All MINIpowerPLUS 5000 Rack-mounted UPS
cabinets also contain the UPS batteries; however
a matching rack-mounted battery cabinet is
available if an extended battery facility is required.
Where used, the separate battery cabinet (also
6U) and UPS cabinet should preferably be fitted in
the same rack and positioned immediately
adjacent to each other.
Due to the weight of the assembly it is usual to
mount the UPS cabinet and optional battery
cabinet (where used) near the bottom of the rack.
There is no minimum space requirement above or
below the UPS cabinet when it is in-situ, but a
minimum of 200mm should be provided at the
rear of the unit to allow for adequate cooling air
flow and facilitate cabling. As the UPS cabinet is
600mm deep this implies a minimum rack depth of
800mm.
As mentioned above, rear access is required for
cabling therefore sufficient room should be
provided behind the rack to permit easy passage
– recommended 900mm. A similar space is
required at the front of the rack to enable the UPS
cabinet to be handled while it is being installed.
3.2.3 Environmental considerations
The following conditions apply to both Tower and Rack-mounted installations.
• The UPS location should be subject to a humidity of less than 90% (non-condensing) and temperature
between +15°C to +25°C. An ambient temperature of 20°C is recommended for optimum battery life.
• The location should be free from dust or corrosive/explosive gases.
• The location should not be subject to vibration.
• The air conditioning system must be able to provide a sufficient amount of cooling air to keep the room
at, or below, the maximum permissible operating temperature.
CAUTION: The UPS cabinet is heavy.
Ensure that sufficient personnel and
appropriate handling equipment are
available to install the unit safely.

Extended battery cabinet connections
Additional battery cabinets can be
connected to either of the above
systems to further extend the available
autonomy time.
Where an extended cabinet is used, the
standard cabinet inter-connect cables
are replaced by ‘splitter’ cables that can
be effectively daisy chained to connect
any number of cabinets together – as
illustrated in Figure 3.6.
When several cabinets are connected as
shown, the battery charger within the
UPS cabinet may not be able to
adequately charge all the additional
batteries. In this case an independent
battery charger is fitted to each extended
battery cabinet which must be connected
to a mains supply using a standard IEC
power cord.
3.3.2 Connecting the UPS communication options
On the UPS cabinet back panel there
are three D-type connectors that provide
various optional communication
facilities.
The 9-pin female connector provides an
RS232 communications port that can
interface with a range of monitoring and
control software – such as the CS121L
Adapter Box for WaveMon, or other
monitoring software using SNMP and
MODBUS.
The remaining connectors (9-pin male)
provide logic output signals that can be
used to drive remote alarms and indication facilities – this is normally carried out via a relay interface board
(See paragraph 7.3.1).
The following output signals are provided:
These outputs can be used individually or connected to an optional Remote Signalling Panel (RSP).

3.3.3 Connect the UPS input/output power cables
The UPS input and output cables are fitted to a single power connector that plugs into a receptacle located
on the rear UPS cabinet wall. A ready-made connector complete with cable is provided with the equipment.
The supplied cable is approximately 600mm in length and terminated with an input plug and outlet socket
suitable for the UPS capacity rating. Where the supplied cable length is inadequate for a particular installation
it can be replaced by a longer cable following the instructions contained at the end of this section.
Note: If the UPS connector is fitted with a maintenance bypass switch refer to the Options chapter in this
manual for details (See paragraph 7.1).
MINIpowerPLUS 5000 power cables
A cable with a maximum capacity of 16A is supplied with the MINIpowerPLUS 5 000. For ap plications where
the anticipated UPS input current exceeds 13A (e.g. 5000 VA with Vin=184V) we recommend that the UPS
input power cable is connected directly to the electrical distribution control panel . If this requires a longer
power cable the connector can be rewired as shown below in Figure 3.9.
MINIpowerPLUS 10000 power cables
A ready-made cable of approximately 600mm in length, fitted with stan dard IEC connecto rs, is supplied with
the UPS. If it is necessary to rewire the connector the cable must be a minimum of 4mm² and have insulated
wires – see Figure 3.10.
Figure 3.8 UPS input/output power receptacles
Connecting the UPS power connector
1. Connect the UPS input/output power connector assembly to the power receptacle on the rear of the UPS
and secure in place using two screws, as shown in Figure 3.8.
2. Check that all the UPS loads are turned OFF then connect the UPS output cable to the load d istribution
point.
3. Connect the UPS input mains supply cable to a power outlet adequate for the voltage and current
required.
Key Point: A link is fitted in the power connector which ensures that the UPS cannot be started
unless the connector is plugged-in to the UPS power receptacle.
CAUTION: Before proceeding, either ensure tha t the UPS input power cable is disconnected from
the mains supply or, if the cable is connected directly to the main s, ensure that the mai ns supply is
isolated at the distribution point.

3.3.4 Powering ON the UPS
If the UPS batteries are already fitted and connected you can apply power to the UPS at this stage and,
provided the power-on indications described below are satisfactory, you can put the UPS into operation.
1. Ensure the load equipment is turned OFF or otherwise isolated from the UPS output supply.
2. Turn ON the UPS input mains supply.
3. The UPS is fitted with protection against incorrect power connections. If the red warning light on the UPS
control panel is permanently illuminated (not flas hing) and the internal warning buzzer is continuously
sounding you should immediately turn off the input mains power supply, disconnect the UPS power
connector and seek the manufacturer’s advice.
4. If the initial power-on indications (above) do not indicate a fa ult, you can connect the load equ ipment to
the UPS output and switch ON the UPS following the Operating Instructions contained in Chapter 4 of
this manual.
Important final checks
As current dispersion towards earth of all the loads merges in the UPS protection wire (earth wire), for safety
reasons, it is essential to check that the sum of these currents does not exceed 2.7 mA, according to BS EN
62040-1-1:2003.
WARNING: If the batteries are not already fitted and connected:
• Do not continue beyond this point in the installation procedure. The equipment must be
commissioned by a manufacturer-approved engineer.
• Do not turn on the input mains power until the equipment has been commissioned.

4.4.3 UPS Setup Menu
The UPS Setup menu is used to set-up various UPS operating parameters and functions. This menu can be
password protected to prevent unauthorised access – see ’Operator Panel sub-menu’ on page 4-10.
Output sub-menu
Frequency: This can be set to a nominal value (i.e. 50Hz or 60Hz) or it can be configured as AUTO whereby
the UPS output frequency synchronises to the input mains frequency and changes to the nominal value (50/
60Hz) if the input mains supply fails.
N+x Redundancy: Where a system is designed to incorporate a number of redundant power modules, the
UPS contains more power modules than is required to power the full connected load. Therefore the system
could lose one (or more) power module before its ability to provide full load power is affected.
The N+x Redundancy setting determines the number of modules that can be inoperative before the system
sounds the OUT OF REDUNDANCY alarm. A practical example is shown in the table below:
Input sub-menu
PLL Enable: If enabled, the UPS synchronises the output frequency to the input frequency. If disabled, the
UPS output frequency is not synchronised, the Green status led flashes and th e ‘auto matic by pass’ facility i s
inhibited which means that the load is not fully protected in the event of a UPS fault or overload condition.
Extended PLL Range: When enabled, the UPS output frequency synchronisation range is ±14% of the
nominal input frequency. When disabled this is reduced to ±2%.

Bypass Enable: If enabled, the UPS manages bypass operation automatically. If disabled, the UPS will
never switch to bypass and will switch off in the event of sustained overload or fault.
Forced Mode: If enabled, the UPS is set to operate permanently on bypass. This is the method used to
connect the load to bypass when operating in the ‘ECO’ mode.
DIP Speed: When ‘Forced Mode’ is disabled, this setting alters the speed of bypass intervention.
SLOW: for loads which are may cause high peak demands and are insensitive to input voltage disturbance.
STANDARD: normal condition.
FAST: For loads which are extremely sensitive to input voltage disturbance.
Off-line Mode: If enabled, the UPS operates in permanent bypass mode while mains supply is available and
reverts to battery power if the mains supply fails.
Load Wait Mode: If enabled, the bypass operates normally for loads below the ‘Minimum Load Threshold’
but is not available for higher loads – i.e. for higher loads, during a mains failure the UPS switches OFF and
is only restarts when mains is restored. The threshold value is entered in ‘Watts’.
Programming priority:
Neutral Sensor sub-menu
Enable: If enabled, the UPS uses the neutral sensor to verify that the voltage between neutral and earth is
within safe limits and switches the UPS to battery mode when this is not the case.

Maintenance
5.1 Introduction
As the UPS contains no user-serviceable parts, the maintenance requirements to be ca rried out by the user
are minimal beyond ensuring that the UPS operating environment remains suitably cool and dust-free.
5.2 Routine maintenance
We recommend that the UPS operating parameters are checked and recalibrated annually as part of a
regular maintenance schedule to ensure optimum UPS operation efficient load protection. The batteries
should also be checked annually, depending on the ambient temperature.
When the UPS is commissioned, the commissioning engineer will attach a service record book to the front of
the UPS which will be used to log the full service history of the UPS.
During a preventative maintenance inspection the service engineer will check the following:
• Site environmental conditions
• Integ rity of the electrical installation
• Availability and quality of the cooling airflow
• UPS Rectifier operation and calibration
• UPS Inverter operation and calibration
• UPS Static switch operation
• Battery cond ition and status
• Load characteristics
• Integ rity of the alarm and monitoring systems
• Operation of all installed options
Preventative maintenance inspections form an integral part of all Extended Warranty Agreements
(maintenance contracts) offered by Uninterruptible Power Supplies Ltd. For further details on Extended
Warranty Agreements see Section 2 of this manual.
5.3 Battery Testing
The battery test procedure can be activated from the UPS operator panel an d can performed independ ently
of the UPS operating mode (Off-line or On-line) and whether or not the load is connected.
WARNING: All the maintenance operations described in this chapter must be performed by an
authorised electrician or other suitably qualified personnel.
WARNING: Preventative maintenance inspections entail workin g inside the UPS with safety
covers removed. This presents a risk of electric shock due to the unavoidable exposure to
hazardous AC and DC voltages, and should be undertaken only by trained engineers
authorised by Uninterruptible Power Supplies Ltd. who are fully aware of the hazardous areas.

Troubleshooting
6.1 Potential Problems and Solutions
Problem Possible Solution
When the UPS is switched on, the buzzer sounds and the red
warning light makes alternating short-long flashes, then the
UPS switches off after 15 seconds.
The connection of the neutral conductor is incorrect:
• Swap the connections of the neutral and phase input
leads, or exclude the neutral sensor.
The UPS works but a short beep is heard every 12 seconds
and the yellow warning light is lit without flashing.
Check power is present at the mains outlet.
• Check that the UPS power supply cable is correctly
inserted in both the mains outlet and in the connector
on the UPS itself.
• Check the fuse located at the side of the input/output
connector under the plastic housing (see Figure 3.8).
The UPS works but it beeps intermittently and the red
warning light and the yellow warning light are flashing.
There is an overload on the UPS output.
• Reduce the load so that it does not exceed the
maximum power that the UPS can supply.
• Alternatively, if the UPS is not in its maximum
configuration, you can ask your Service Centre to
increase the power of your UPS by fitting extra power
modules and batteries inside the UPS cabinet.
The UPS beeps continuously and the yellow warning light
flashes for about 15 seconds, after which the UPS switches
off.
The UPS has completely flattened its batteries; it can only
start up again when the mains input line is present.
• Check the magneto-thermal or differential switches
that precede the UPS and the input fuse.
The UPS works but the green warning light is flashing quickly. The mains supply is out of the limits permitted for the voltage
and/or frequency, but it can still be used by the UPS.
However, the by-pass function is not operational.
The UPS beeps intermittently and the red warning light is
flashing quickly.
The thermal protection has been tripped.
• Switch the UPS off and wait for a few minutes so that
the internal temperature of the UPS can get back to
normal.
• Check that the fans operate correctly and that the
airflow is not obstructed (e.g. if the UPS is too close
to a wall).
• If the above step are satisfactory, there is likely to be
a fault on one of the internal circuits. Contact your
service centre.

7.1 Maintenance Bypass
7.1.1 Introduction
Figure 7.1 Maintenance bypass circuit
The Maintenance Bypass option allows the load to be transferred to the raw input mains supply if it is
necessary to completely shut down or remove the UPS for maintenance or repair purposes.
The maintenance bypass switch controls two relays, one of whi ch is connecte d in the bypass circuit and the
other in the UPS output line (see Figure 7.1). When the maintenance bypass switch is OPEN (0) the UPS
output relay is closed, energised from the UPS output supply via a normally-closed switch contact, and the
bypass relay is open. Conversely, when the maintenance bypass switch is CLOSED (1) the bypass relay is
closed, and the UPS output relay is opened. This interlocking action prevents the UPS output from being
back-fed from the raw mains supply.
Key Point: When the load is connected via the maintenance bypass supply it is not protected
against mains failure or other power aberrations.

Both relays and the maintenance bypass switch are built in to the UPS power connector (which replaces the
standard power connector). The switch contains a yellow lamp which illuminates when the switch is closed to
indicate that the load is connected to the maintenance bypass, as shown below in Figure 7.2.
Figure 7.2 Maintenance bypass switch location
7.1.2 Installation
This procedure provided details of how to replace the standard UPS power connector with the optional
maintenance bypass power connector.
1. Isolate the load and turn off the UPS.
2. Isolate/disconnect the UPS input mains supply cable and the UPS output supply cable to the load
distribution point.
3. Disconnect and remove the power connector from the UPS power receptacle after first removing the two
securing screws that hold it in place.
4. Dismantle the standard power connector and disconnect the input and output power cables – for details
see Figure 3.9 and Figure 3.10.
5. Feed the input/output power cables removed from the standard connector (above) through the cable
glands in the new connector’s cover – observe the connection details in Figure 7.3 or Figure 7.4 to
determine the correct orientation.
6. Connect the input and output cables to the replacement Maintenance Bypass Connector as shown in
Figure 7.3 or Figure 7.4. – take care to ensure the cables are connected to the correct terminal blocks.
7. Tighten the cable gland ring nuts to hold the cables securely in place then attach and secure the
connector’s cover using the four M3 screws provided.
8. Connect the reassembled power connector to the UPS power receptacle and secure it in place using the
two screws removed in step 3.
9. Install the two self threading screws provided with the bypass if the UPS chassis is complete with the
corresponding holes.
10. Do not turn ON the UPS until the installation has been functionally tested, as described below.
WARNING: The maintenance bypass switch option must be installed by qualified personnel.
Key Point: Ensure it is safe to disconnect load power before proceeding.
This procedure requires the UPS to be completely shut down and isolated from the ma ins supply.

7.2 Shutdown and Monitoring Software
7.2.1 Introduction
Power disruptions and depleted battery conditions pose the greatest threat to valuable computer data
integrity. However, the risks inherent in these conditions can be alleviated by using a network management
tool to monitor the UPS power supplies and alarm status.
By installing UPS/Mains monitoring software an administrator can monitor the utility power from a central
location and obtain an early warning of impending power problems, even across more complex systems such
as the Wide Area Networks (WAN) and Enterprise Wide Networks of multi-national companies.
To avoid a power loss due to depleted batteries, caused by a mains failure that exceeds the battery
autonomy time, the UPS management software can initiate an automatic and con trolled computer shutd own
when the battery reaches a predetermined point in its discharge cycle. The allows valuable data to be saved
and the operating system to be shut down gracefully before the power is lost.
Four monitoring systems are available for use with the MINIpowerPLUS UPS system:
• WAVEMON – can be used for monitoring and automatic shutdown
• SNMP – can be used for monitoring only
• PowerREPORTER – can be used to automatically email UPS monitored parameters and alarm
events to Uninterruptible Power Supplies Ltd. for appropriate response
• RELAY INTERFACE BOARD – provides volt free contacts for connecting to a remote alarm monitor
7.2.2 WAVEMON UPS monitoring software
WAVEMON is designed to operate with many of the Uninterruptible Power Supplies Ltd. UPS systems and
features both monitoring and automatic server/UPS shutdown facilities. The system comprises a bespoke
software package which is installed on a local PC and communicates with the UPS over a standard RS232
cable connected to the RS232 port on the UPS back panel. The interconnecting RS232 cable can be up to
15m in length and may be connected/disconnected whilst the UPS is running.
The main characteristics of WAVEMON are:
• On-screen autonomy time/battery time countdown
• On-screen server log off and shutdown procedure
• Time an d date stamp event log
• Extensive logging of all UPS activity and power quality data
• Al l ow alarm warnings to be monitored remotely via email
• Scheduled UPS service mode and other systems status
• Graphical user interface for Windows-compatible platforms
• Automatic unattended local shutdown
• Special modules for MS-Office software to close and save open documents
• Compatible with all optional modules like UPSDIALER, SNMP adaptors, temperature sensors, etc.

WAVEMON Operation
The UPS-Management software is a client/server-application for networks and local workstations and
consists of two parts: the server-module of the UPS-Management Software is called UPSServ and the clientmodule UPSCli.
The server-module (UPSServ) communicates with the UPS via the RS-232 cable and works as a background
process which collects messages from the UPS, interprets them and then makes them available to the clientmodule (UPSCli) and to any operating SNMP-based management station.
When UPSServ detects a voltage variation or a power failure it can be programmed to execute various
‘system event’ routines, which for example may shutdown the server or send a warning message to
connected users. These routines are a part of the UPS-Management Software a nd their functionality can be
adjusted to suit the user’s demands.
RCCMD - Remote Console Command module for a multi-server shutdown
In some situations it is preferab le to interface the MINIpowerPLUS to the network via an SNMP adapter,
which allows up to 50 computers to be shut down in a RCCMD environment.
RCCMD (Remote Console Command) is an additional software module, which can be triggered by the SNMP
device to execute a command (typically a shutdown command) on a remote system.
The MINIpowerPLUS can be integrated into a network by means of the server which is being powered by the
UPS if it is already integrated into the network. In most cases the server is used as a sub-agent and you only
need the PMC-Software without any SNMP Adapter. You need a standard serial connection between the
RS232 port of the UPS and the RS232 port of the computer/server.
Licence conditions
The UPS management software includes the licence for using the UPS service on one server with one UPS
and an unlimited number of connected Windows workstations. When operating with two or more servers, a
further licence is required for each additional server, irrespective of whether the UPS service runs at that
location or if the server is halted by a UPS service via remote command (RCCMD).
The same licence conditions apply to the use of remote send/receive modules (RCCMD) and multi-server
shutdown under NT, UNIX and other operating systems. The service programs are generally delivered as a
single-licence. To use a single CD ROM to shutdown multiple servers you must purchase additional CD
license keys.

7.2.3 SNMP ADAPTER for network management/remote monitoring
Simple Network Management Protocol (SNMP) is a world-wide standardised communication protocol that
can be used to monitor any network-connected device vi a a simple control lang uage. The monitore d results
are displayed in a web browser.
When this facility is used in conjunction with the MINIpowerPLUS, an external SNMP adapter is used which is
connected to the RS232 connector on the UPS back panel. The SNMP adapter is then connected to the
network by means of a standard RJ-45 terminated Ethernet connector.
The adapter is enclosed in a small box which must be powered from a backed-up supply supported by the
UPS output so that its power is maintained in the event of a mains failure. A suitable plug-top power supply is
included with the option kit.
Note: It is the customer’s responsibility to provide a suitable, backed-up mains supply for the adapter.
The UPS-Management software agent installed in the SNMP adapter monitors the UPS operating
parameters and outputs its data in SNMP format to the connected network.
In order to use this adapter the operating system you are using must be SNMP-compatible. We offer our
software with SNMP functionality together with NetWare, OS/2, all Windows NT systems on INTEL and
ALPHA. The SNMP adapter requires a PC with terminal connections, and for normal operation at least one
Ethernet network connection is also required.
