Protective conductor
The protective conductor must be connected up both on the mains side
and on the motor side.
On account of leakage current through the interference-suppression
capacitors the following must be observed as per EN 50178
• A minimum cross-section of 10 mm
• If supply connections with cross-sections less than 10 mm
used, two protective conductors have to be connected up. The
cross-section of each of the protective conductors corresponds to
the cross-section of an outer conductor.
If the unit is mounted on a grounded mounting surface via a conductive
connection, the protective conductor cross section can be the same as
that of the phase conductor. The function of the second protective
conductor is afforded by the grounded mounting surface.
There is an additional ground connection in the form of an M4 threaded
bolt at the upper section of the unit located next to the X1 mains
connection
.
This is used for connecting up the second protective conductor in
accordance with EN 50178.
The mains connection is situated at the top of the unit.

The connector has to be screwed firmly to the housing (providing
resistance to vibration and protecting against being inadvertently
withdrawn).
