4. General
4.1 Prologue / Warning
This instruction manual and the device are intended to be used
by users who know about the principle of a power supply. The
handling of the device should not be left to persons who are
unaware of the basic terms of electrotechnology, because these
are not described in this manual. Inappropriate handling and
non-observance to the safety instructions may lead to a damage
of the device or loss of warranty!
4.2 Cooling
The air inlets on the front and the air outlets at the rear have
to be kept clean to ensure proper cooling. Take care of at least
20cm distance at the rear to any surrounding objects in order
to guarantee unimpeded air ow.
4.3 Opening the device
When opening the unit or removing parts from the inside with
tools there is risk of electric shock by dangerous voltages.
Open the unit only at your own risk and disconnect it from the
mains before.
Any servicing or repair may only be carried out by trained perso-
nnel, which is instructed about the hazards of electrical current.
Opening the unit is normally only required to replace a fuse.
4.4 Redundancy
Certain models feature redundancy. It means, they contain two
or three power stages and if at least one power stage is remai-
ning operable, because other power stages have switched off
due to overheating, the power supply will continue to provide
power to the output.
5. Installation
5.1 Visual check
The unit has to be checked for signs of physical damage after
receipt and unpacking. If any damage is found, the unit may not
be operated. Also contact your dealer immediately.
5.2 Input connection (single unit)
The unit‘s AC input requires a three-phase supply, plus ground
(PE).
The connection is done with cables of proper cross section.
See table for examples. The table takes regard of connecting
one unit.

15kW 4mm² 28A 4mm² 28A 4mm² 28A
We recommend to use
for 10kW/15kW models: at least 4mm²
for every phase and ground (PE).
5.3 Input connection (multiple units)
If multiple units of same or different power rating are connec-
ted to the same three-phase main connection, it is required to
consider the current of the phases in order to gain a balanced
distribution. Models with 10kW will cause an unbalanced current
distribution when using 1 or 2 units. On the other hand, 3 units
would be ideal.
Example conguration for 10kW models:
5.4 Input fuses
Fuse protection of the unit is done with up to 6 fuses of type
Littlefuse F16A/500V and size 6.3x32mm. They are located
inside the unit on a mains lter board which is located behind
the front plate. In case fuses need to be replaced, the top cover
has to be removed.
5.5 DC output terminal
The power output is located on the rear of the device.
The output is not fused! In order to avoid damage to the load
application, always take care for the nominal values of the load.
The cross section of the load leads depends on several condi-
tions, like the output current, the lead length and the ambient
temperature.
Up to 1.5m cable length we recommend to use:
up to 30A: 6mm² up to 70A: 16mm²
up to 90A: 25mm² up to 140A: 50mm²
up to 170A: 70mm² up to 210A: 95mm²
up to 340A: 2x70mm² up to 510A: 2x120mm²
at least per DC output pole (exible wire).
Single cables like, for example, 70mm² can also be replaced
by 2x 35mm².
When using longer cables it is required to increase cross section
in order to avoid voltage drops and unwanted heating.
