Shielded MOTION-CONNECT 500 and 800 line supply cables are recommended in order to
maintain the EMC limit values. The line supply cable is connected at interface X1 (INPUT).
The single cores of the cable are labeled with U, V, W and PE. Cables are connected at the
S120 Combi corresponding to the terminal labeling.
The cable shield should be connected and fixed using the shield clamp.

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.
Damage to unshielded power cables due to shield connection clamps
When using unshielded power cables, the unshielded individual cores can be damaged by
the shield connection clamp.
• Only use the shield connection clamp for shielded power cables.
