Control unit.
1. In the cabinet, remove shrouding wherever necessary to allow access to the cable
entries and any trunking inside the cubicle.
2. Run the control cables into the cubicle. If possible, arrange for a 360° grounding of the
cable shield at the cable entry.
If the outer surface of the shield is non-conductive, turn the shield inside out as shown
below and wrap copper foil around the cable to keep the shielding continuous. Do not
cut the grounding wire (if present).

3. Run the cables to the control unit of the inverter (or other connection point) using cable
trunking wherever possible.
4. (Only when running the cable to the inverter module) The inverter control units have a
clamp plate attached. Remove the outer sheathing of the cable at one of the clamps
on the plate. Tighten the clamp onto the bare cable shield.
5. Cut the cables to suitable length.
