Mounting the strain relief
All models in this series have a strain relief for the AC cable in their scope of delivery. It’s recommended to be mounted and
used by the installer, unless a different kind of strain relief is intended. Installation steps:
1.
Remove the two screws from the AC filter box as marked in
Figure 11 below.
2.
Place the bracket and fix it with the included, longer screws (M3x8) and spring/curved washers.
3.
Plug the AC plug and lead the cable in front of the bracket, when seen from behind, and fix it with at least one, better
both of the included cable ties.
The bracket and the cable ties can remain connected all the time. The AC plug has some space to be pulled if required. Should
the device be removed from the installation (cabinet), it’s recommended to only pull the plug and dismount the bracket.

Grounding the enclosure
From production date of approx. 01/2022, the devices feature a separate grounding point
on the rear side, as depicted on the figure to the right and marked as item “7” or “8” in
Views”).
For reasons of safety for people working with the device which, amongst other measures, is
achieved by keeping the leakage current as low as possible, the enclosure can be grounded
additionally to the standard grounding via the AC cable. It’s done be laying a separate protec-
tive earth line (PE) of the same or higher cross section as in the AC cable and connected here.
