NOTICE
Bearing damage
The bearing insulation must not be bridged. Bearing currents can damage bearings.
● Do not bridge the bearing insulation for subsequent installation work, such as the
installation of an automatic lubrication system or a non-insulated vibration sensor.
● Please contact the service center if necessary.
Tandem operation
If you connect two motors in series in "tandem operation", install an insulated coupling between
the motors.

NOTICE
Bearing damage
Bearing currents can flow if the coupling between the motors of the tandem drive is not
insulated. This can damage the DE bearings of both motors.
● Use an insulated coupling to link the motors.
