5.3.5 Logic Ground Cables

The logic ground cables are a part of the internal power distribution. They provide a ground
connection between the backplane of each system shelf and the system ground bar in the
Control Frame (CF). The logic ground is connected from each shelf to the fuse and alarm
panel by the consolidated power cables, cable #6 AWG (P/N 690-0131-R01), terminal lug (P/
N 804-0817-R02), and heat-shrink (P/N 804-0228-01).
Note:
It is a requirement that when mating dissimilar metals non oxidizing grease is used
between them as a corrosion inhibitor.
Run green cable, #6 AWG (P/N 690-0131-R01).
1.
Butt, strip, and apply non oxidizing grease to conductor.
2.
The stripped cable must fill lug completely to the end of the barrel of the lug and be
visible in the end window of the lug.
Place clear heat-shrink on butted end of wire below stripped end.
3.
Place lug onto the stripped end of the cable and crimp the lug using embossing dies.
4.
The stripped cable must fill lug completely to the end of the barrel of the lug and be
visible in the end window of the lug.
3U Fuse and Alarm Panel Rear (P/N 870-2320-03))
