Note
Pay particular attention to the relubrication intervals for rolling bearings that deviate from the
inspection intervals.
Note
When servicing a three-phase machine, it is generally not necessary to dismantle it. The
machine only has to be dismantled if the bearings are to be replaced.

First inspection after installation or repair
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 (Page 58).
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
Machine damage
When carrying out the inspection, if you detect any impermissible deviations from the
normal state, you must rectify them immediately. They may otherwise cause damage to the
machine.
