[6] PE conductor
The connection points for ground connection or equipotential bonding are on the hous-
ing corners [1] of the device. They are marked with a "ground" icon .
Note the different cable cross section of the supply system cable of devices with three-
phase current during installation. Refer to the "Supply system cable" chapter for more
information.
1. Push the terminal clip [2] onto the connection point.
2. Take a screw [4] and push a serrated lock washer [3], the crimp cable lug for the
PE [6] or the HF litz wire [5] and another serrated lock washer [3] onto it.
3. Tighten the screw [4] with a maximum tightening torque of 5 Nm using a wrench.
Supply system cable
Leakage currents ≥ AC 3.5 A/DC 10 mA may occur during normal operation. Proceed
as follows depending on the cable cross section of the supply system cable:
Supply system cable < 10 mm

:
Perform the installation steps again and route a second PE with the same cable
cross section as the supply system cable in parallel to the PE via separate termin-
als. Alternatively, use a copper PE conductor with a cable cross section of
10 mm
