Cleaning
Careful and regular maintenance, inspections and overhauls make it possible to
identify and eliminate faults in good time before they can cause any damage.
Operating conditions and characteristics can vary widely. For this reason, only general
maintenance intervals for trouble-free operation can be specified here. Maintenance
intervals must be matched to the local conditions (dirt, frequency of starts, load, etc.).
If problems or unusual conditions arise which might cause electrical or mechanical
overstressing of the motor (e.g. overload, short circuit), carry out the necessary
inspection work immediately.
7.2.1 Supervision of operation
DANGER
Rotating or live parts
Death, serious injury or damage to property!
▷
If covers have to be removed, de-energise the motor beforehand.
▷
Avoid touching live or rotating parts.
DANGER
Hot surface
Risk of burns!
▷
Never touch a motor when it is in operation.
▷
Let the motor cool down.
▷
Only remove covers if indicated.
WARNING
Condensing air humidity inside the motor if the motor and/or ambient
temperatures frequently change
Risk of corrosion by condensation!
▷
Always observe the information provided on ambient conditions.
While the system is in operation, observe and check the following:
▪
Deviations from normal operation such as increased power consumption,
temperatures or vibrations, unusual noises or odours, tripping of monitoring
devices, etc.
▪
If rough running or abnormal noises are detected, switch off the motor and find
the cause of the problem as the motor coasts down.
–
If mechanical operation improves immediately after the motor is switched
off, the causes are magnetic or electrical phenomena.

At least every 6 months
4)
At least every 2 years
