NOTICE

• Only use suitable DRIVE-CLiQ cables that have been approved by Siemens for the
particular application.

Special features for Motor Modules with external air cooling
Note
Insufficient cooling power when the external heat sinks are polluted
For components with external air cooling, the fan and the heat sinks can accumulate a lot of
pollution. If the cooling air requirement is not provided by the filt
er fan, the components
cannot output their specified power. This can cause the temperature monitoring function in
the components to respond.
•
Check the fans and heat sinks for pollution at regular intervals and clean them when
necessary.
Note
Checking the seal
•
After installation, check the seal on the rear of the device to ensure that it is tight.
•
If required, use additional sealing.
Note
Using an installation frame
•
Only use an installation frame when the cabinet has an unpainted metal surface.
Notes for UL applications
Note
The SINAMICS S120 Motor Modules Booksize provide short
-circuit protection at the motor
output terminals.
