Operation
8.1 Safety instructions for operation
Danger as a result of stationary parts under voltage (live parts)
Live parts represent a hazard. Touch protection against active (live) parts is no longer
guaranteed if covers are removed. The minimum air and creepage distances may be fallen
below (violated) when coming close to active parts. Touching or coming close can result in
death, serious injury or material damage.
• Carefully ensure that all of the covers are closed while operational.
• First switch off and disconnect the motor if you must remove covers. Carefully comply
with the "5 safety rules" (Page 139).
• When the motor is in operation, the terminal boxes must remain closed at all times.
Terminal boxes may be opened only when the motor is stopped and in a no-voltage
condition.
Faults in operation
Any changes with respect to the normal condition can indicate that the motor is not
functioning correctly.
• Higher power consumption, temperatures or vibration levels.
• Unusual noise or smells.
• Monitoring devices respond.
These changes can cause faults which can result in eventual or immediate death, serious
injury or material damage.
• Immediately inform the service personnel.
• If you are in doubt, immediately switch off the motor, carefully observing the system-
specific safety conditions.
Corrosion damage as a result of condensation
Humidity can condense inside the motor if the motor and/or ambient temperatures fluctuate,
for intermittent operation or load fluctuations.
Condensation can accumulate. Moisture can have a negative impact on the winding
insulation or result in damage, such as corrosion.
• Ensure that any condensation can freely flow away.
• If available, remove the screw plugs to drain the water depending on the ambient and
operating conditions.
• If available, reinsert the screw plugs.
If the motor is equipped with drain plugs, then the water can drain away by itself.
