AuxBus Cabling

1.
Connect the AuxBus cable between the filter and the power unit. If there are several power units and filters, connect each filter
to the power units individually.
a.
Connect the end of the AuxBus cable where the insulation was removed to terminal X79 on the power unit.
b.
Connect the other end of the AuxBus cable to terminal X86 on the filter.
Use the tightening torque 0.22–0.25 Nm (1.9–2.2 in-lb).
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 X79 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.
