Ground Connection of Housing
The ground connection of the housing is used to provide functional safety of
the drive controllers and protection against contact in conjunction with the
equipment grounding conductor.
Avoid spark discharge of static charges!
In some applications (e.g. printing or packaging), high static
charges can develop. Make sure that these charges can be di‐
rectly discharged against ground at their point of origin. If neces‐
sary, install additional lines between the fixing points of the motor
flanges (charge acceptance) and the ground connection of the
drive system (e.g. mounting surface of the drive controllers in the
control cabinet).
Ground the housings of the devices:
1. Connect the bare metal back panel of the device in conductive form to
the mounting surface in the control cabinet. To do this, use the supplied
mounting screws.
2. Connect the mounting surface of the control cabinet in conductive form
to the equipment grounding system.
3. Connect the bare metal back panel of the mains filter in conductive form
to the mounting surface in the control cabinet. Connect the mounting
surface of the mains filter with the lowest possible impedance (over a
