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.
Notice
The external air cooling can cause the fans and the heat sink to become heavily
contaminated, which may trigger the temperature monitor in the power section. The fans and
heat sink must be checked for contamination at regular intervals and, if necessary, cleaned.
Note
After installation, the seal on the rear of the device must be checked to ensure that it is tight.
Additional sealing can be used, if necessary.
Note
The mounting frames can only be used if the cabinet has an unpainted metal surface.
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).
