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. Comply with the
"Five 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.
This 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.
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.
