5.4.3 Motors with external earth conductor connection
For motors with external earth conductor connection, the earth conductor is connected via the
ground terminal on the motor housing.
The earth conductor to be connected must be labelled in accordance with IEC 60445 and have the
following properties:

Loosen the screw of the ground terminal.

It is not necessary to fully unscrew and remove the screw.

Push the PE conductor under the clamp.

Tighten the screws with a tightening torque of 2.0 Nm.
Not connecting the earth conductor may lead to electrostatic
discharges which can lead to explosions. Explosions can cause
serious injuries and even death.

Ensure that the earth conductor is properly connected.
