2. Route the cable so that there is no risk of getting in touch with bare busbars or terminals.
3.
Ground each AuxBus cable at 1 end at the X85 terminal. To make the grounding connection, attach the shield of the cable to
the frame with a cable clamp.
The lower part of the cable clamp fixes the cable to the plate and provides strain relief. The upper part provides ~360°
grounding for the cable shield.
