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.

Installation
Observe the following when carrying out any work on the machine:
● Comply with the general safety instructions (Page 1)
● Comply with the applicable national and sector-specific regulations.
● When using the machine within the European Union, comply with the specifications laid down in EN 50110-1 regarding
safe operation of electrical equipment.
5.1
Conformity
Loss of conformity with European directives
In the delivery state, the machine corresponds to the requirements of the European directives. Unauthorized changes or
modifications to the machine lead to the loss of conformity with European directives and the loss of warranty.
5.2
Preparing for installation
The following requirements must be satisfied prior to starting installation work:
● Staff have access to the operating and installation instructions.
● The machine is unpacked and ready for mounting at the installation location.
Note
Measure the insulation resistance of the winding before starting installation work
Measure the insulation resistance of the winding before starting any installation work. If the insulation resistance lies
below the specified value, take appropriate remedial measures. These remedial measures may necessitate the machine
being removed again and transported.
Note
Note also the technical data on the rating plates on the motor enclosure.
