9.1.2 Static charging when cleaning
Risk of explosion due to static charging
If you clean the motor, plastic components may become statically charged and ignite a
potentially explosive atmosphere. An explosion can occur. This can result in death, serious
injury or material damage.
● When cleaning ensure that there is absolutely no explosive atmosphere present.
● Clean the plastic parts and components so that absolutely no static charging occurs
● Do not use compressed air for cleaning.
9.1.3 Inspections in the event of faults
Natural disasters or unusual operating conditions, such as overloading or short circuit, are
faults that overload the machine electrically or mechanically.
Immediately perform an inspection after such faults.
9.1.4 First inspection
● Check after approx. 500 operating hours, but after not more than one year:
Check When the
motor is
running
At stand-
still
The electrical parameters are maintained. X
The permissible bearing temperatures are not exceeded. X
The smooth running characteristics and machine running noise have not
deteriorated.
X
The foundation has no cracks or indentations. (*) X X
(*) You can perform these checks while the motor is at standstill or, if required, while running.
● Further checks may be required if so specified in operating instructions of components or
in accordance with the plant-specific conditions.
● If you find any deviations during the inspection, you must rectify them immediately. They
may otherwise damage the motor.
