About the device
3.2 Scope of delivery
1 x Power supply unit
1 x Printed user manual(s)
1 x Plug for Share bus (plugged)
1 x Plug for remote sense (plugged)
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 flow.
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. Refer to section „2.2 Device specifications“
to find out which models feature redundancy.
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 two (3.3kw/5kW models) or three
phases (6.6kW/10kW/15kW) models of 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.

We recommend to use
for 3.3kW/5kW/6.6kW models: at least 2.5mm²
for 10kW/15kW models
at least 4mm²
for every phase and ground (PE).
The selection of the phase pair to use for a 3.3kW or 5kW model
is arbitrary for one unit. Means, it does not necessarily has to
be L2(R) and L3(S):
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 distribution of the phases in order to gain
a balanced one. Models that require only two phases will result
in an unbalanced current distribution when using 1 or 2 units.
On the other hand, 3 units would be ideal.
