Motor installation, continued
The air gap must be checked at at least three positions (each offset to 120).
Iftheadjustmentisrepeatedthethicknessofthebrakeliningmustbechecked.
Brakes are safety-related components.
Brake liners and friction discs are not sold as separate parts.
Brakes are only available as a complete set.
Converter operation
When operating the motors on the frequency converter the converter manufacturer’s EMC notes must be observed. Appro-
priate suppression measures must be taken. Metal shielded cables and cable glands should be provided.
The motor’s torque depends on the respective converter.

Themotormustbeprotectedfromexcessiveoverheatingbycoldconductors,thermocontactsand/orbyexternalfans.
Motor protection
Motor protection switches (overload protection) must be set to the current value specified on the rating plate depending on
the voltage.
Thermo contacts are normally designed as openers.
The resistance of cold conductors (PTC’s) at 20 °C is not significant. The value may vary between 60  and a maximum of 750 .
External fans
The voltage and wiring of the external fan are different depending on the type of fan.
The external fan has a separate terminal box.

Some external fans can only be operated in single phase.
Other fan motors can be operated both in single phase in a Steinmetz circuit and also in triphase.

driven machine so that potential overloads and asymmetries on the mains side can be detected immediately.
