Safety Instructions In Operation - Parts That Are Not Covered, And That Are Under Voltage (Live Parts) - Siemens 1FP1/3 Operating Instructions Manual

Operation
8.1 Safety instructions for operation
8.1.2 Safety instructions in operation - parts that are not covered, and that are
under voltage (live parts)
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" (Page 15).
• In operation, the terminal box must always be kept closed. It is only permissible to open the
terminal box when the motor is stationary 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.
• 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.
