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 machine if you must remove covers. Carefully comply
with the "5 safety rules".
• When the machine is in operation, the terminal boxes must remain closed at all times.
Terminal boxes may be opened only when the machine is stopped and in a no-voltage
condition.
Faults in operation
Any changes with respect to the normal condition can indicate that the machine 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 machine, carefully observing the system-
specific safety conditions.
Corrosion damage as a result of condensation
Humidity can condense inside the machine if the machine 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.
Only switch on the anti-condensation heating (if equipped) after the machine has been
switched off. Carefully comply with the data on the anti-condensation heating plate.
Risk of burn injuries as a result of hot surfaces
Individual machine parts can become hot in operation. Burns can result when coming into
contact with these parts.
• Never touch machine parts during operation.
• Allow the machine to cool down before starting work.
• Check the temperature of parts before touching them. If required, wear suitable protective
equipment.
