SECTION 2.3: 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 transmitter cabinet, as viewed
from the rear.
2. Remove the outer (exterior) nut and re-assemble as shown in Figure 2.3.1 on page 2.3.2 . 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.
Ensure the reference ground conductor is at least 3 mm (1/8 in) from the cabinet’s exterior.
3. Verify it is still possible to open the rear door of the transmitter with the reference ground
conductor connected. If you use a copper strap for the conductor, you may need to trim its width
slightly near the door.
4. For information about grounding the lightning protection, see the
NX5/NX3 Pre-Installation
