Power cables for motors

The motor power cables are connected at interfaces X2 to X5. The single cores of the cable
are labeled with U, V, W and PE. The cables are connected corresponding to the terminal
labels at the S120 Combi.
When using a power cable with connection cables for the motor holding brake, the cores for
the motor holding brake are connected at interface X11 (see the diagram below). In this
case, connect the cable shield of all cable cores. Fix the cable shield using the shield clamp.
When using a separate cable for the motor holding brake, the cable shield should be
connected to a shield support of a motor power cable that is free. If there is no longer a free
shield support, connect the cable shield of the brake cable to the connection at the outer
right together with the cable shield of the motor power cable.

NOTICE
The shield clamp does not provide strain relief. Strain relief for the power cable must be
separately realized using a suitable measure.
