Danger!
Uncontrolled motor movements may occur
Under certain conditions, the motor may rotate after mains connection.
Possible consequences:
ƒ Near the machine or plant, situations may arise that are hazardous to
persons.
ƒ The machine or plant may be damaged by an unexpected start.
Protective measures:
ƒ Commissioning with external 24 V supply and without mains voltage
ƒ Remove motor connector X21. An active motor temperature monitoring
prevents a motor voltage from being output. If the monitoring is
deactivated, a voltage may be applied at the plug.
ƒ Ensure that no setpoint is applied.
