gefunden werden..
Due to the possibility of existing energy storage (accumulators) within a UPS,
devices must generally be inspected by EFFEKTA Regeltechnik GmbH or a
qualified service center after transportation damages. In the case of
transportation damages, there is a 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 unit must be
isolated until an inspection has been performed.
In addition, the device should not be transported or stored upside-down.
2.6 Positioning
Only operate the UPS in well-ventilated rooms, ensuring the specified ambient
temperature range (according to 13 Technical dat).
The UPS should not be placed in the vicinity of heat sources. In the event of
increased ambient temperature (higher than 25°C), the life span of the battery
will decrease considerably; as a result, the battery’s warranty will be terminated.
Always take the operating conditions into account when positioning the device.
Maintain the minimum distance to adjacent equipment and walls necessary for
ventilation purposes (see 13 Technical dat and 5 Installation and
connection of the UPS ensure that the necessary air circulation is provided.
Never place or operate the device in a moist environment. Liquids must, as a
rule, be 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
two hours must be observed before any further steps are taken. Make sure 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 explosive and/or unventilated setting.

UPS: MKD 6-10 kVA RT
Safety Instructions
MKD Series
15
2.7 Connection
Always use the connection terminals or blocks provided for the purpose of
connecting the UPS.
To avoid electrical hazards, the connection of the unit must only be made under
de-energized conditions.
The PE (protective earth) conductor must be connected without fail. The UPS-
device, as well as the connected loads, must not be used without the PE
conductor under any circumstances!
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 labelled!
In addition, the following points must always be followed when connecting the
UPS:
–Install all connections appropriately and keep the cable length as
short as possible;
–Only use suitable power cables when connecting the UPS to the
mains power supply and pay attention to the required current
carrying capacity;
–Only use suitable power cables when connecting appliances to the
UPS and pay attention to the required current carrying capacity;
–The safeguarding of any appliance must always be performed
immediately in front of an appliance and may never be performed
centrally in front of the UPS;
–Never operate any household devices or tools such as e. g. fan
heaters, vacuum cleaners, electric drills, hairdryers, toasters, etc. by
means of the UPS;
–Do not connect any appliance to the UPS that could overload the
device;
–In general, only use appropriate tools for the installation.
2.7.1 EPO, Emergency Power Off for loads

UPS: MKD 6-10 kVA RT
Safety Instructions
MKD Series
16
Should an emergency power-off circuit “EPO”or “REPO”(REMOTE
EMERGENCY POWER OFF) be installed, this control circuit must
unconditionally be separated from all other electrical circuits by reinforced
insulation.
The purpose of an EPO connection is for emergency power off and the
release of the loads.
2.8 Operation
Only qualified personnel are permitted to access and operate the device.
In all situations, it must be kept in mind that the UPS includes an energy storage
or is connected to an external energy storage unit. This means that the UPS
outlet can be current-carrying even when the UPS has already been
disconnected from the mains power supply.
Consequently, the UPS output is guaranteed to be de-energized only when the
device has completely shut down and has been disconnected from the mains
power supply.
2.9 Working with accumulators
When handling accumulators, there is always a risk of electric shock, burns
and/or chemical burns.
For this reason, unauthorized personnel should not have access to
accumulators.
Accumulators or their circuit points can cause electric shock.
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
into contact with open fire. Explosion hazard!
Accumulators should never be opened or destroyed. The electrolyte released
presents a great danger to your health and the environment. It could result in
chemical burns to skin and eyes; moreover, the electrolyte is very toxic.
Defective accumulators must be disposed of an in environmentally friendly
manner!

UPS: MKD 6-10 kVA RT
Safety Instructions
MKD Series
17
Never dispose of accumulators with regular household waste!
Local disposal regulations must be observed!
2.10 Maintanence, service and malfunctions
Attention –risk of electric shock.
Even after switching off the supply with the power button or after disconnecting
the accumulator feed, parts of the UPS can still carry high voltages.
The following precautions must be taken when working on the UPS and the
accumulators:
–Before beginning work on the UPS, it must first be switched off and
disconnected from the mains power supply and the loads.
–Remove wristwatches, jewelry and other metallic objects;
–Use only isolated tools;
–Work on live equipment must only be performed by specially trained
personnel. These persons must wear the appropriate personal
protective equipment (PPE) at all times;
–The UPS may not be disassembled;
–Work on the accumulators must only be carried out and supervised
by personnel with the required expertise concerning safety
regulations;
–Unauthorized personnel are to be kept away from the UPS and the
accumulators.

3. UPS device description
This UPS device is an ONLINE UPS after the double conversion principle.
Based on the outstanding performance according to EN 62040-3, the UPS
receives “Class 1” (VFI-SS-111) classification. This way subsequently
connected appliances will be optimally provided for, irrespective of how a
primary source of power (mains power supply) performs.
Malfunctions such as: mains power failure, power supply undervoltage, power
supply overvoltage, temporary mains voltage changes (transients), subtle mains
power deviations, frequency changes, etc. will not be transferred to the
connected loads in standard operating mode.
The UPS is used to support sensitive devices and facilities such as, e.g.:
computers, servers, emergency systems, electronic cash registers, instruments
critical to operation critical, telecommunication facilities, processor control
systems, surveillance and management systems, etc.
A conversion to autonomous time follows by way of the adaption of an external
battery bank or its capacity.
3.1 Topology and operating modes
The following figure (Fig. 3-1), a block diagram of the UPS device, clearly shows
the double conversion principle. The mains power supply is converted to the DC
intermediate circuit whereby the energy storage (battery bank) is charged. The
loads, or appliances, on the UPS output are fed without failures or interruptions
by an additional conversion (INVERTER).
Fig. 3-1 Topology, function groups for the UPS device.
It is clear that, within the mains power supply, failures do not reach the UPS
output and, consequently, the load. Furthermore, all operation modes of the
UPS device can be derived from and represented by the above mentioned block
diagram:

UPS: MKD 6-10 kVA RT
UPS Device Description
MKD Series
19
Standard operation mode (INVERTER MODE)
The standard operation mode is characterized here by a classic double
conversion. The supply network is converted to the DC intermediate circuit
which then feeds the UPS output through an inverter (DC/AC converter). The
by-pass is inactive here.
Fig. 3-2 Operating mode: standard operation.
Support or autonomous mode (BATTERY MODE)
In the event the supply network temporarily fails, the inverter draws power
directly from the battery bank and thereby supplies the UPS output without
interruption. The autonomous mode is limited by the capacity of the battery bank
and its charging status.
Fig. 3-3 Operating mode: autonomous mode.
Static by-pass operation mode (FAULT MODE)
Often in the case of a device fault (fault mode) with the inverter, the UPS
automatically and without interruption of the UPS output switches to the static
by-pass operation mode. In doing so, the load feed is securely maintained over
the power supply, albeit without the support function of the UPS. Once the fault
has been eliminated, the device returns to normal operation mode. Malfunctions
can also be caused by the loads such as when the UPS is overloaded.

UPS: MKD 6-10 kVA RT
UPS Device Description
MKD Series
20
Fig. 3-4 Operating mode: static by-pass.
Never leave the UPS in the static by-pass mode, or the fault mode, for a long
period of time. The loads will continue to be supplied yet without any support
function from the UPS.
The static by-pass mode can also be intentionally switched on, e.g. for
screening.
Power saving mode (ECO MODE)
The “power-saving mode,” called ECO MODE, is a feature of the MKD series.
The UPS device is intentionally operated in the static by-pass mode for this
purpose. In this, the inverter remains inactive but operation ready whereby the
UPS consumes considerably less power (LINE INTERACTIVE). The device
automatically converts to autonomous mode only in the event of power failures /
faults. However, the use of the ECO-MODES is then only sensible when the
loads are robust” devices which have low tolerance for switch and power supply
fluctuations during the by-pass mode.
Fig. 3-5 Operating mode: ECO MODE (Static Bypass).
The operating mode (ECO-MODE) is not recommended for sensitive loads as
many malfunctions such as, e.g. transients, penetrates the by-pass and could
affect the loads. The same applies as long as the UPS is not fed over the public
network but rather by a generator.
