Section 5: Connecting the station
reference ground
To connect the station reference ground, perform the following steps:
1. Locate the station reference ground stud at the bottom left of the output cabinet, as viewed
from the rear.
2. See Figure 5.1 on page 5-2 . Remove and retain the outer (exterior) nut (2), split washer (4)
and flat washer (3).
3. Attach a continuous, low impedance conductor (minimum four-inch copper strap, or
equivalent wire) between the site’s station reference ground and the transmitter’s station
reference ground stud (1). 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 transmitter’s station reference ground stud and the transformer
cabinet’s station reference ground point (see Figure 4.3 on page 4-5 ). Ensure the reference
ground conductor is at least 3 mm (or 1/8 in) from any cabinet’s exterior.
5. Reinstall flat washer (3), split washer (4) and nut (2) removed in step 2 on the transmitter's
station reference ground stud (1) and firmly tighten all hardware.
Note:
Proper grounding configuration is critical for protecting transmitter circuitry from
lightning strikes. See the Electrical Requirements section of the
NX400 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.
