2.3.3 Connecting the IRD Ground Wire
Agrounding wire (Cable #32-0583-50) has been provided to
connect your IRD to a suitable ground and protect the system.
Attach the grounding wire to any suitable screw on the rear
panel of the IRD with a good contact with the IRD chassis. The
other end should be connected to a suitable ground, ideally the
ground connector on the switchplate (see Figure 2-15).
2.3.4 Installing the Switchplate
After completing the switchplate wiring process, you must install
the switchplate itself. This process, detailed in the following
steps, is illustrated in Figure 2-16.
1. Fit the switchplate assembly and support frame
into the panel cutout made in Step 2 of Section 2.3,
“Connecting System Components,” and flush to the
mounting surface.
2. Drill out four 5⁄32" (4 mm) holes in the countersunk
settings in the switchplate support frame.
3. Drill four 3⁄32" (2.5 mm) holes in the mounting
surface using the countersunk holes in the support
frame as the template. Secure the support frame
and switchplate assembly to the mounting surface
using four #6 self-cutting screws.
4. Snap the front cover into place to cover the screws
and support frame.
5. Reinstall the vessel fuse removed in Step 1 of
Section 2.3.2, “Connecting to Vessel Power.”

Mounting the Switchplate
Support Frame and Front Cover
Before securing the switchplate to
the mounting surface, be sure to
strain-relieve the wires connecting
to the switchplate connectors.
Several tie-wraps have been
provided to aid in strain-relieving
the wires.
