Wiring
4.2 Control interfaces
Note
If terminals 3 to 6 are not used, then you must connect 24 V DC to them. To do this, use an
external power supply or terminal 9 on the Control Unit.
The reference potential is connected to terminal X9.2 and X9.7, and terminal 28 on the Control
Unit.
Note
Line contactor control
If the line contactor is controlled via terminals 11 and 12, then it is not necessary to use a control
transformer to provide isolation from the line supply. A 250 V/8 A fuse must be used as
protection.
Note
Insulated end sleeves
Insulated end sleeves according to DIN 46228-4 must be used.
Note
Strain relief
For strain relief, the cables to the Control Unit and to the terminal X9 must be fastened to the
lugs in the cable duct below terminal X9 (e.g. with cable ties).
If the cables are introduced at the side (at the height of terminal X9), the strain relief must be
provided outside the Power Module.
