Power supply routing

The power supply can be routed from the front, left and right side.
1 Left and right side. The plastic conduit hole on the left and right
side can be opened as follows:

1 Power supply inside a conduit
2 Conduit
3 Power supply
4 Cut off the shaded zones before usage
5 Through hole cover
2 Front side.
In order to route the power supply from the front side, the
available knockout holes can be used:
1 2
1 Knockout hole
2 Burr
3 If there are any possibilities that small animals enter the
system through the knockout holes, plug the holes with
packing materials (to be prepared on-site).

Precautions when knocking out knockout holes

To punch a knockout hole, hit on it with a hammer.
After knocking out the holes, we recommend removing any burrs
and paint the edges and areas around the holes using repair
paint to prevent rusting.
When passing electrical wiring through the knockout holes,
prevent damage to the wires by wrapping the wiring with
protective tape, putting the wires through field supplied
protective wire conduits at that location, or install suitable field
supplied wire nipples or rubber bushings into the knockout
holes.
