NOTICE
Bearing damage
The bearing insulation must not be bridged. Bearing currents can damage bearings.
● Also when performing subsequent installation work, e.g. installing an automatic lubrication
system or a non-insulated vibration sensor, ensure the bearing insulation is not bridged.
● Contact your Service Center, if necessary.
