NOTICE
Bearing damage
The bearing insulation must not be bridged. Damage may be caused to the bearings if there
is a flow of current.
● Also for subsequent installation work, such as the installation of an automatic lubrication
system or a non-insulated vibration sensor, make sure that the bearing insulation cannot
be bridged.
● 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
If the coupling between the motors of the tandem drive is not insulated, bearing currents can
cause damage to the drive-end bearings of both motors.
Use an insulated coupling to link the motors.
If you connect two motors in series in "tandem operation", fit a coupling between the motors;
this coupling should satisfy Directive 94/9/EC or the regulations that apply in the country where
the equipment is installed..
