5.1.6 Do not bridge the bearing insulation
The machine is fitted with an insulated bearing cartridge. The bearing cover and the bearing
cartridge are insulated from the bearing shield and the motor enclosure with insulating parts.
The insulation means that the motor (housing, stator, shaft) represents an open conductor
loop.
NOTICE
Bridged bearing insulation
It is not permissible that the insulation is bridged when instruments are mounted, such as
vibration measuring systems, relubrication equipment, etc. Circulating currents in the motor
cause bearing damage at the drive and non-drive end.
● Only connect lubrication tubes, shock-pulse measurement sensor, bearing cover, etc. with
other motor parts or the motor ground with the appropriate insulation.
