How to Connect Frame Ground and Logic Ground
Procedure 6-1.
1.
Butt and strip the ends of the green ground cable (P/N 690-0108-07 for the
frame ground and P/N 690-0131-01 for the logic ground).
2.
Slide a clear heat-shrink (P/N 804-0229-01 for the frame ground and
P/N 804-0228-R01 for the logic ground) on the butted end of the cable below
the stripped end. Move the heat-shrink past the stripped portion of the cable
to allow access to the uncovered wire.
3.
Apply a thin layer of non-oxidizing grease to the uncovered wires.
4.
Slide the cable lug (P/N 804-0977-R01 for the frame ground and
P/N 804-0817-R02 for the logic ground) over the stripped cable. Crimp the
lug on the cable, using an embossing crimper. The stripped cable must fill the
lug completely to the end of the barrel and be visible in the end window of the
lug.
5.
This procedure is complete.
Next, go to "How to Ground the Frame in a DC Environment" on page 6-4
How to Ground the Frame in a DC Environment
This section describes how to ground the frame.
Procedure 6-2.
1.
Ensure that Procedure 6-1 on page 6-4 to prepare the frame ground cable
(P/N 690-0108-07) has already been performed.
2.
Attach the continuous aisle ground conductor 1/0 to the Ground Window.
Run the conductor to the equipment (see Figure 6-1).
3.
Install the branch ground conductor to the frame using screws and washers.
The continuous aisle ground conductor will be H-tapped to the branch (see
Figure 6-1). The separate #6 American Wire Gauge (AWG) cable ground that
runs to the frame will allow removal of a frame from a lineup without
interrupting the grounding of any other frames in the lineup. Torque screws
to 45 inch-pounds.
