Note On Shielded Cables; Electromagnetic Compatibility - Siemens SINAMICS GL150 Operating Instructions Manual

Damage caused by incorrectly shrinking cable terminations
When connecting line and motor-side power cables, when shrinking the cable terminations,
other control cables can be damaged in the adjacent/surrounding cable ducts.
● When shrinking, ensure not to damage cables in the surrounding cable channels.
Material damage caused by incorrectly opening doors
If you incorrectly open the doors, then this can damage the locking mechanism.

Note on shielded cables

Note
We recommend using shielded cables. Unshielded cables can transfer disturbances to the
control and signal lines and lead to malfunctions in the drive.
Note
To ensure trouble-free operation without interference or disturbances, route the power cables
and signal lines separately. Interference, for example, will result in the device not behaving as
expected.
When connecting and routing power and signal cables, observe the instructions contained in
the "Electromagnetic compatibility" section.
