Bolt locking devices

Replacing the sensor module

Safety information
Warning
If you operate a different sensor module on the motor, this can result in serious injury or
death, or cause considerable material damage.
The sensor module contains motor-specific and sensor-specific data and an electronic
nameplate. This is why you must only use the sensor module on the original motor. You
must not fit the sensor module to other motors or replace it with a sensor module from
another motor.
