Connecting the L-412.xx9025E1 to the Protective Earth Conductor

The L-412.xx9025E1 must be connected to the protective earth conductor via the drive
connector: For this purpose, the protective earth connector on the motor plug on the drive
electronics side must be connected to an earth connection.
If the load needs to be connected to the protective earth conductor, the L-412.xx9025E1's
base body must also be connected to the protective earth conductor. In this case, connect
the load and base body to the protective earth conductor separately.
The following description offers an example of how to connect the protective earth
conductor to the base body of the L-412.xx9025E1.
