Section 5: Connecting the station
reference ground
To connect the station reference ground, perform the following steps:
1. Locate the safety ground stud assembly for the output cabinet. It has been set back in its
final location at the bottom left rear of the cabinet.
2. Remove the two nuts holding it to the phenolic bar.
3. Re-assemble as shown in Figure 5.1 . Attach a continuous, low impedance conductor
(minimum four-inch copper strap, or equivalent wire) between the station reference ground
and the stud assembly (E1) in the output cabinet. Ensure the reference ground conductor is
at least 3 mm (1/8 in) from the cabinet’s exterior.
4. Attach a continuous, low impedance conductor (minimum four-inch copper strap, or
equivalent wire) between the stud assembly (E1) in the output cabinet and the transformer
cabinet’s ground stud. Ensure the reference ground conductor is at least 3 mm (or 1/8 in)
from any cabinet’s exterior.
5. Firmly tighten all hardware.
Note:
Proper grounding configuration is critical for protecting transmitter circuitry from
lightning strikes. See the Electrical Requirements section of the
NX300 Pre-
Installation Manual or the Recommendations for Transmitter Site Preparation Manual for
information on proper grounding and lightning protection recommendation.
Failure to follow these guidelines may void your warranty.
