Warning
Cable shields and unused power cable conductors (e.g. brake conductors) must be
connected to PE potential to prevent capacitive cross-talk charges.
Non-observance can cause lethal shock voltages.
Caution
Only cables from Siemens must be used for DRIVE-CLiQ connections.
Note
A regulated DC power supply is required to operate motors with a built-in holding brake. The
voltage is supplied via the internal 24 V busbars. The voltage tolerances of the motor holding
brakes and the voltage drops of the connection cables must be taken into account.
The DC power supply should be set to 26 V. This ensures that the voltage supply for the
brake remains within the permissible range when the following conditions are fulfilled:
• Using Siemens three-phase motors
• Using Siemens MOTION-CONNECT power cables
•
Caution
The left and right ends of the DC link busbar of a drive line-up must be fitted with peripheral
covers (order no.: 6SL3162-5AA00-0AA0).
