6.6 Brake motor
Connection of brake motors should be according to the following circuit diagrams.
The brake is already wired to the motor at delivery. For a separate power supply to the brake
please disconnect the U1 - 2 and V2 - 1.
The control voltage for the brake is indicated at the rating plate.
For a fast acting brake (de-switching) a separate cable to an external contact is necessary. The
contact must be protected with a varistor.
6.7 Installation with frequency inverter
For operating F-motors with a frequency inverter please follow EMC instructions of the frequency
inverter.
Screened cable and metal cable glands are required.
The output torque of the motor depends on the type of frequency inverter in use.
The rectifier of the brake requires a separate power supply.
The motor must be protected against overheating by PTC resistor, thermal contacts or forced ven-
tilator.

6.8 Motor protection

Motor protection switches (overload circuit breaker) must be adjusted to the current according to
the voltage indicated at the rating plate.
Thermal contacts are break contacts (NC) as standard.
The resistance of PTC thermistors at 20°C can vary from 90 Ω to maximum 750 Ω .
