2.1 Introduction
The UPS is a device that has been produced according to the rules and regulations of technology for an uninterruptible power supply.
The device is safe when used properly and under consideration of the safety requirements and
instructions provided in this operating manual.
2.2 Proper Use
The UPS and its related components may only be used for purposes in accordance with its design – to supply electric appliances from a primary source and to
provide a short-term supply for the appliances from a secondary source, which
does not exceed the nominal power in total. Any other use beyond that is considered improper and can result in personal injury, damage to property or to the
device!
The device is not designed for use in
– explosive;
– dusty or humid;
– radioactive or;
– biologically or chemically contaminated atmospheres!
For information of the respective IP protection class of the device please contact
our service centers.
In addition, the device class with regard to “electromagnetic compatibility”
(EMC) has to be taken into consideration. There is no radio interference to be
expected with devices of Class C1. However, devices classified as Class C2
can cause radio interference in the home/residential areas. In this case, the operating party may be requested to take appropriate remedial measures!
Therefore, please take note of the information regarding the device category in
the specifications listed (13 Technical Data).

2.3 Avoiding Personal Injury / Property Damage
– Please read this operating manual carefully to familiarize yourself
with the device and its functionality. Do not, under any circumstances, ignore the safety instructions.
– In particular, take note of the information regarding the installation
and commissioning of the device.
– Only operate the product only in an appropriate and proper way and
always within the specified performance parameters. (13 Technical
Data).
– Only perform maintenance and service work that is described in the
documentation. Follow the instructions steps as specified. Only use
original replacement parts from EFFEKTA Regeltechnik GmbH
2.4 Protecting the Environment
Send the product back to EFFEKTA Regeltechnik GmbH after the end of its
service life. We will ensure environmentally responsible disposal.
2.5 Transport and Storage
The UPS may only be transported to the intended location in the original packaging. The same applies to moves or returns.
The packaging has a very good protective function with regard to the device. By
inversion of this argument, all devices that were damaged in the course of transportation must be inspected by EFFEKTA Regeltechnik GmbH prior to their
commissioning. The same applies in general for any damage to the device.
If the period of storage exceeds 4 months, the accumulator bank of the UPS
equipment must urgently be charged; see also 4.1 Storage of the UPS.
Due to the possibility of existing energy storage (accumulators) within a UPS,
devices must in general be inspected by EFFEKTA Regeltechnik GmbH or a
qualified service center after transportation damages. Every transportation damage carries the high risk that the energy storage units and/or their electrical connections have been affected. As a result, short circuits and/or the leaking of
electrolytes cannot be ruled out. For this reason, the isolation of the unit is necessary, until an inspection has been performed.
In addition, the device may not be transported or stored upside-down.
MCI 700, 1000, 2000, 3000 VA (XL)
Safety Instructions
MCI series
14
2.6 Positioning
Only operate the UPS in well ventilated rooms, within the specified ambient temperature range (according to 13 Technical Data).
The UPS may not be placed in the vicinity of heat sources.
Always take the operating position into account when positioning the device.
Maintain the minimum distance to adjacent equipment and walls required for
ventilation purposes (see 13 Technical Data and 5 UPS Installation and
Connection). Ensure that the necessary air circulation is provided.
Never place or operate the device in a moist environment. Liquids must generally kept away from the device.
Due to major temperature differences, condensation or dew effects may occur
after the positioning of the UPS. Therefore, an acclimatization period of at least
2 hours is to be observed, before you take additional steps. Make sure that the
temperature adjustment has been completed and that any surfaces with condensation inside and outside the device have completely dried.
Never operate the UPS in an combustible and/or unventilated environment.
2.7 Connection
Always use the connection terminals provided for this purpose for the connection of the UPS.
To avoid electrical hazards, the connection of the unit may only be made under
de-energized conditions.
The PE (protective earth conductor) must be connected without fail. The device
and the connected loads may not, under any circumstances, be used without
the PE!
The UPS output is supplied with power even in the event of a power outage; according to the provisions included in EN62040-1, the lines and power outlets
supplied by the UPS must be clearly marked!
In addition, the following aspects must always be complied with when connecting the UPS:
MCI 700, 1000, 2000, 3000 VA (XL)
Safety Instructions
MCI series
15
– Install all connections appropriately and keep the cable length as
short as possible;
– Only use suitable power cables for the connection of the UPS with
the electricity grid and ensure the required current carrying capacity;
– Only use suitable power cables for the connection of the loads with
the UPS and ensure the required current carrying capacity;
– The safeguarding of any appliance must always be immediately in
front of an appliance and may never be done centrally in front of the
UPS;
– Never operate any household devices or tools like e. g. fan heaters,
vacuum cleaners, electric drills, hair dryers, toasters, etc. via the
UPS.
– Do not connect any appliance to the UPS that could overload the de-
vice;
– Only use appropriate suitable tools for the installation;
2.8 Operation
Access to the unit as well as its operation is reserved to qualified personnel
only.
Attention must always be paid to the fact that the UPS includes an energy storage or is connected to an external energy storage unit. This means that the outlet of the UPS can be current-carrying even when the UPS is already disconnected from the mains power supply.
Consequently, the UPS output is only guaranteed to be de-energized, when the
device is completely shut down and disconnected from the mains power supply
2.9 Working with Accumulators
When handling accumulators there is always a risk of electric shocks, burns
and/or chemical burns.
Therefore, unauthorized persons should never have access to the accumulators.
MCI 700, 1000, 2000, 3000 VA (XL)
Safety Instructions
MCI series
16
Accumulators and their circuit points can cause electric shocks.
In the event of a short-circuit of the accumulators, touching the current-carrying
parts can result in severe burns.
Do not place accumulators in the vicinity of heat sources and do not bring them
in contact with open fire. Explosion hazard!
Furthermore, never open or destroy accumulators. The released electrolyte pre-
sents a great danger to health and the environment. It could result in chemical
burns to skin and eyes, and electrolyte is very toxic.
Defective accumulators have to be disposed of in an environmentally compatible manner!
Never dispose of accumulators with regular household waste!
Local disposal regulations must be observed!
2.10 Maintenance, Service and Malfunctions
Attention – Danger of electric shocks.
Even after switching off the supply with the power button or after disconnecting
the accumulator feed respectively, parts of the UPS can still carry high voltages.
MCI 700, 1000, 2000, 3000 VA (XL)
Safety Instructions
MCI series
17
The following aspects have to be considered, when carrying out work on the
UPS or the accumulators:
– Before you begin any work on the UPS, it must be switched of and
disconnected from the power grid and from all the appliances.
– Remove wrist watches, jewelry and other metallic objects;
– Use only isolated tools;
– Work on live equipment may only be carried out by specially trained
qualified personnel. They must always wear the appropriate personal
protective equipment (PPE);
– As a rule, the UPS may not be disassembled.
– Only trained electricians with sufficient knowledge of the required
safety regulations may perform work on accumulators or supervise
such work tasks;
– Unauthorized persons should not have access to the UPS and the
accumulators;

Device Description

3. UPS Device Description
This UPS-unit is an ONLINE-UPS according to the double conversion principle.
The UPS receives the classification "Class 1 (VFI-SS-111) due to the excellent
operating performance pursuant to EN62040-4. Consequently, any appliances
connected via the unit can be ideally supplied, regardless of the performance of
the primary energy source (mains power supply).
Malfunctioning like: mains failure, low voltage on the mains power supply, grid
overvoltage, short-term grid alterations (transients), gradual supply voltage deviations, frequency changes, etc. are not transmitted to the connected loads under normal and autonomous operation.
The UPS is designed to provide a consistent power supply to sensitive devices
and equipment like, e.g.: computers, servers, emergency systems, electronic
cash registers, operations-critical instruments, telecommunication facilities, process control, monitoring and control systems, etc.
The MCI-Series includes an internal accumulator bank as secondary energy
source. A possible extension of autonomy periods is possibly through the adaption of an external accumulator bank or the extension of its capacity. If very high
autonomy periods (capacities) are required, the XL models must be used, as
these models provide a significantly higher charging rate.
3.1 Topology and operating modes
The following diagram (Fig. 3-1), a block diagram of the UPS-unit, clearly shows
the double conversion principle. The mains power supply is converted into the
DC-intermediate circuit, which charges the energy storage (accumulator).
Through an additional conversion (INVERTER) the connected loads on the UPS
output are supplied without malfunction or interruption.
Fig. 3-1 Topology, functional groups of the UPS-equipment.
As can clearly be seen, no power failures or disruptions of and within the mains
power supply reach the UPS output and thus the loads. In addition, all operating
modes of the UPS-system can be derived and described from the above block
diagram:

Device Description

Normal operating mode (INVERTER-MODE)
The normal operating mode is characterized here by the typical double conversion. The mains power supply is converted into the DC intermediate circuit,
which in turn feeds the UPS output via the inverter (DC/AC converter). In this
mode, the BYPASS is inactive.
Fig. 3-2 Operating mode: Normal operation.
Back-up or autonomous mode (BATTERY-MODE)
In the event of a temporary mains failure, the inverter feeds directly from the accumulator bank and supplies the UPS-output without interruption this way. The
autonomous mode is limited by the capacity of the accumulator bank and its
charging condition.
Fig. 3-3 Operating mode: Autonomous operation.
Static by-pass mode (FAULT MODE)
Usually due to a device error (fault mode) inside the inverter, the UPS automatically and without interruption switches the UPS output to static BYPASS mode.
This ensures that the power supply to the loads is maintained. from the mains
power supply, however, without the support function of the UPS. Once the malfunction is cleared, the equipment returns to normal operating mode. Malfunction can also be cause by the connected appliances, e.g. when the UPS is overloaded.

Fig. 3-4 Operating mode: Static BYPASS.
Do not leave the UPS in static by-pass mode or fault mode for any extended period of time. Even though the appliances continue to be supplied, no backup
support function is provided by the UPS.
The static BYPASS mode can also be set manually on purpose, e.g. for inspection purposes.
The energy saving mode (ECO MODE)
One special feature of the MCI series is its "energy saving mode", called ECOMODE. For this, the UPS device is intentionally operated in static BYPASS
mode. In this mode, the inverter remains inactive but ready for operation, and as
a result, the system consumes significantly less power (LINE-INTERACTIVE).
Only in the event of a mains failure / mains malfunction or disruption the UPS
automatically switches into autonomous mode. However, the application of the
ECO-MODE recommended, if the loads are “robust” devices that are able to tol-
erate the minor switching and grid fluctuations during BYPASS mode.

This operating mode (ECO-MODE) is not recommended for sensitive loads, as
certain disturbances like, for example, transients can penetrate the by-pass and
can affect the loads. The same is true, if the UPS is not supplied from the public
power grid, but alternatively from a generator.
Converter Mode (CVF MODE)
In addition to the standard operating modes, the UPS can also be switched into
a converter mode. In this mode, the UPS operates functionally equivalent to its
normal operating mode, however, the UPS output is not mapped to the mains
input, rather, the INVERTER operates (convertingly) according to defined output
parameters, irrespective of the power units at the input. This means, an appliance can be supported and operated that would in fact not be compatible with
the available grid.

All variants are housed in the standard free-standing case (TOWER). Correlating to the power output values, two casing sizes are being used (M and L).
All models can in general be operated with an external accumulator bank,
whereby the total capacity equals the sum of the capacity of the internal and the
external accumulator bank. The accumulator banks too are housed in casings of
the same dimensions (M and L), depending on the UPS model.
