S120 Combi Power Modules
4.8 Electrical connection
SINAMICS S120 Combi
106 Manual, 11/2017, 6SL3097-4AV00-0BP7
The motor power cables are connected at interfaces X2 to X5. The single cores of the cable
are labeled with U, V, W and
. 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, its cable shield should be
connected to the associated shield support of the motor power cable.

Damage to the shield connection clamp when strain relief is not used
The shield clamp does not provide strain relief. In the event that strain relief of the power
cable is not carried out separately using appropriate measures, the shield connection clamp
may be damaged.
• Install additional strain relief for the power cable.
