AC Line Cord
–
380V~480Vac “
-
4” Models
The included connection plug can receive soldered cable ends or such with cable end
sleeves of up to 6 mm² for 380V~480Vac “-4” models. The longer the connection cable, the
higher the voltage loss due to the cable resistance. Therefore, the mains cables should be
kept as short as possible or use a bigger cross section. If possible, all three phase of a three-
phase supply should be wired so that no phase is missing if the cable is going to be used for
another model with different power rating.

Strain Relief and plug fixture
There is a standard fixture mounted to
the AC input connector block on the rear.
It is used to prevent the AC plug from
loosening and disconnecting due to
vibrations or other mechanical shock. The
same fixture is also used as strain relief.
Using the 4x M3 nuts, it is recommend to
mount the fixture to the AC filter block
every time the AC plug has been
unplugged and plugged in again.
It is furthermore recommended to install
the strain relief by using suitable cable
straps (not included), as depicted in the
figure to the right.
5.6.7
Gird Connection Variations
Depending on the max. power rating of a certain model, it requires two or three phases of a
three-phase AC supply. In case multiple units with 5kW or 10 kW power rating are
connected to the same mains connection, it is important to ensure balanced current
distribution on the three phases. The table in paragraphs 5.6.2 and 5.6.3shows the phase
currents.
