3 Safety
3.1 General safety instruction
Read and observe the user manual and safety instructions in this chapter before
taking any further action (transportation, storage, connection, start-up etc.).
Since the UPS equipment uses mains voltage and has a suitable energy
accumulator (high-capacity batteries) installed either inside or outside the
device, the instructions in this chapter are very important for all users and
personnel. For this reason, appropriate safety instructions on the topic of
batteries and battery packs are also dealt with here. When using external battery
packs, you must also follow the safety instructions in the accompanying
instruction manual.
Work on the UPS equipment may only be performed by authorized technical
personnel.
3.2 Transport and storage
When storing equipment, make sure that it is also securely positioned.
The equipment must not be transported or stored upside down.
Position the equipment securely during transportation taking its centre of
gravity into account. Due to its weight, UPS equipment with integrated batteries
may drop suddenly if its position shifts slightly.
When storing equipment, make sure that it is also securely positioned.
3.3 Placement
The UPS is intended for use in ventilated rooms.
During setup or installation, the installation location prescribed by the
manufacturer must be observed.
There is a risk of condensation where the UPS is exposed to extreme and
rapid temperature changes. Before taking any further steps, the equipment
should be allowed to acclimatize for at least 2 hours.
Never set up or operate the equipment in a damp environment.
Keep fluids away from the equipment.
The UPS must not be set up near heat sources.
Ensure that the vents of the equipment are not blocked and that the circulation
of air is not impeded.

UPS MKD2000/3000 Manual
MKD Series
Page 8 of 44
3.4 Connection
Only connect the UPS to an earthed shock-proof socket or, where a terminal
clamp is used, be sure to connect the protective earth conductor. Under no
circumstances should the equipment be operated without a protective earth
conductor.
The house installation socket must be easily accessible and located in the
vicinity of the UPS. In the case of a fixed connection, ensure that the shortest
possible cable lengths are used.
In case of generator mode, there hast o be a polarized connection of the UPS.
Only use VDE-tested and CE-labeled electrical cables to connect the
consumer load to the UPS. In the case of a fixed connection to the consumer
load, a suitable cable must be used.
The fuse protection for the consumer load must always be installed directly in
front of it, and never centrally in front of the UPS.
Do not operate any household appliances and power tools, e.g. fan heaters,
vacuum cleaners, drills, hairdryers, toasters etc., via the UPS.
Do not connect any consumer loads to the UPS which could overload the
equipment (e.g. laser printers).
The sum of the earth fault currents of all consumer loads connected to the UPS
must not exceed 3.5mA.
Keep the connecting cables as short as possible and always lay these
correctly. Avoid the dangers of laying connecting cables in locations where
they may be tripped over, crushed or torn open etc.
3.5 Operation
The mains power cable must never be disconnected during the operation of
the UPS, otherwise the protective earthing of the UPS and the connected
consumer loads will be lost.
Before connecting consumer at the output, the basic configuration (9.2.3) has
to be made. The output voltage with regard to the consumer and the output
frequency during battery service are very important.
The UPS equipment contains an energy accumulator (batteries). This means
that the output of the UPS may be live even if it is not connected on the line
side.
To switch off the UPS completely, first press the switch on the front of the
equipment (OFF position), wait until the UPS has switched off then disconnect
the power supply (switch off the mains input externally or disconnect the UPS
from the mains, e.g. by unplugging it).
Make sure that no fluids or foreign bodies enter the UPS.

UPS MKD2000/3000 Manual
MKD Series
Page 9 of 44
To protect the UPS, avoid constant load of the output over 80% (especially
during battery service). The display of the output load is just supposed to be a
reference value. Separate measurements are necessary to ascertain the exact
output load.
3.6 Handling batteries
Warning –danger of electric shocks and burns.
Batteries can cause electric shocks and are capable of producing high short-
circuit currents which can also inflict burns.
Unauthorized persons must be kept away from batteries.
Do not place batteries against heat sources and do not throw them into a fire as
they might explode!
Do not open or destroy batteries. The electrolyte thereby released is extremely
dangerous to persons and to the environment (danger of chemical burns to skin
and eyes, toxic).
Defective batteries must be disposed of in an environmentally-friendly manner
Never throw batteries into the regular refuse.
The local waste disposal regulations must be observed.

3.7 Maintenance, servicing and faults
Warning –danger of electric shocks.
The UPS remains connected to the battery circuit even after it has been
disconnected from the mains power supply and has a dangerous voltage
potential. Therefore always disconnect the battery circuit before carrying out
servicing or maintenance work and make sure that the equipment is isolated
from the supply
Work on batteries may only be performed and monitored by personnel with
appropriate technical knowledge about the required precautions.
Unauthorized persons must be kept away from batteries.
When working on the UPS, the following precautions must be taken:
Remove wristwatches, rings and other metallic objects
Only use electrically-insulated tools
The UPS must not be deconstructed.

4 Introduction
This manual is intended to provide basic information about single-phase offline
UPS equipment, namely the functional principle, use of the various functions
and the procedure to follow in the event of faults. In addition, this manual
contains information on transportation and storage as well as handling and
installation of the UPS equipment.
The planning guidelines in this manual relate only to the specific requirements
for UPS equipment. The national and local regulations for electrical
installations must be followed without fail during installation.
The contents of the description for this equipment may change as a result of
technological developments. Though we have endeavored to make these
contents as accurate and clear as possible, we would be grateful for
information on any errors which are noted.
We accept no liability for errors in this description or their consequences.
The purpose of UPS equipment (Uninterruptible Power Supply) is to protect
sensitive electrical devices such as computers, workstations, electronic points
of sale, mission-critical instruments, telecommunications equipment, process
controls etc. from faults which may arise as a result of poor power supply
quality or even power failures. Sensitive devices such as these require
comprehensive protection against electrical faults. These may be external
faults (e.g. bad weather, operating faults) or faults caused by adjacent devices
(e.g. motors, air conditioning units, processing machines, welding equipment
etc.). The power supply faults may be summarized as follows:
oFast and slow line-voltage spikes and fluctuations;
oMains power failure;
oFast and slow frequency spikes and fluctuations;
oMains heterodyning or transient voltages.
The UPS equipment monitors the power supply parameters described above
using suitable countermeasures to protect the connected users (e.g.
changeover to support operation in the event of temporary over- or under-
voltage to protect the end devices).

5 System description
The UPS is built following the principle of double conversion. The UPS
supplies an uninterrupted, single-phase voltage to users with mission-critical
applications. In addition to supplying consumer loads, the equipment also
keeps its internal batteries in a fully charged state. In the event of a power
failure or power fault (e.g. voltage fluctuation), the UPS continues, without
interruption, to deliver a clean voltage supply to the UPS output. In support
mode, the energy is drawn from the battery pack.
Fig. 1:
block diagram
MKD series
The block circuit diagram shows the individual modules of the equipment and
provides a general impression of how they interact.
If the mains power failure exceeds the autonomy time of the UPS, it shuts
down to prevent deep discharging of the batteries. When the mains power
supply is restored, the UPS restarts automatically, supplies the consumer
loads and controls the charging of the battery pack.
Outstanding performance characteristics oft he MHD Online UPS are:
oNo interruptions or signal changes in case of primary mains failure.
oPerfect sinus voltage on the output oft he UPS. The quality of the
output voltage is much better than the mains voltage of the in-house
network.
oProcessor controlled bypassing mode (bypass);
oPower Factor correction on the input (>0,95);
oHigh efficiency degree of the inverter >90% DC / AC;
oHigh-performance communications interface (RS232 interface);
oLCD displays status and operation mode

Danger!
All connectings on the back side (except of RS232-interface) have got circuit
potential when attached.
Also when uncoupled dangerous voltage is possible on the connections, due to
loaded capacities in the inside oft he unit.
If all connections of the UPS are existent and the fuse is used, the battery is
automatically in service. This means that the internal battery pack is already in
loading service without that the UPS has been started.
a) Automatic circuit breaker on the power input:
In case of high overcurrents or a fault (e.g. due to an internal short-circuit) the
fuse is activated and the UPS is immediately disconnected to the power
supply.
