Special features for Motor Modules with external air cooling

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 filter 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

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.

Using an installation frame

• Only use an installation frame when the cabinet has an unpainted metal surface.

Notes for UL applications

The SINAMICS S120 Motor Modules Booksize provide short-circuit protection at the motor

output terminals.
