Before startup, make sure that:
•
The drive is undamaged and not blocked
•
All connections have been established correctly
•
The direction of rotation of the motor/gearmotor is correct
•
All protective covers have been installed correctly
During startup, make sure that:
•

6.1.1
Monitoring
•
The MOVI-SWITCH
®
1EM motor starter monitors the power semiconductors of the
motor starter and the motor winding for overtermperature.
•
In the event of overtemperature, the MOVI-SWITCH
®
1EM drive switches off
automatically.
•
The output signal / AS-Interface bit "OK" indicates the monitoring status.
The output signal / AS-Interface bit "OK" must be evaluated by a higher-level
controller.
CAUTION
Risk of crushing due to unexpected start of the drive. If the drive was
switched-off due to overtemperature, it will automatically start up once it has cooled
down.
Severe or fatal injuries.
– If automatic restarting could pose a risk to persons or components, you must
implement an external restart lock.
•
The MOVI-SWITCH
®
1EM motor starter is protected against supply system over-
voltage.
