Perform the following checks after approximately 500 operating hours or at the latest six
months after commissioning:
Table 9-1
Check
The stated electrical characteristics are being observed.
The permissible bearing temperatures are not exceeded.
The smooth running characteristics and machine running noise have not
deteriorated.
The motor foundation has no cracks and indentations. (*)
(*) You can perform these checks while the motor is running or at a standstill.
Additional tests may also be required according to the system-specific conditions.
NOTICE

Main inspection
Check that the installation conditions are observed. We recommend that the following checks
are performed after approx. 16 000 operating hours or at the latest after two years:
Table 9-2
Checking
The electrical parameters are maintained
The permissible bearing temperatures are not exceeded
The smooth running characteristics and machine running noise have not
deteriorated
