reference ground

To connect the station reference ground, perform the following steps:

1. Locate the safety ground stud assembly. It has been set back in its final location at the

bottom left rear of the transmitter..

2. Remove the two nuts holding it to the phenolic bar.

3. Re-assemble as shown in Figure 4.1. Attach a continuous, low impedance conductor

(minimum four-inch copper strap, or equivalent) between the station reference ground and

this stud assembly as shown. Firmly tighten all hardware. Ensure the reference ground wire

is at least 3 mm (1/8 in) from the cabinet exterior.

4. Attach the 6 AWG wire from the safety ground stud assembly to the transformer ground.

See Figure 3.2 on page 3-3.
