• Battery negative should never be common with earth ground.
• For fiberglass enclosures, the backplane inside may be connected to earth ground. Typically, there is a lug specifically for
this connection. The equipment inside the enclosure however, should not be common with the backplane in this case.
• For steel enclosures, battery negative should not be common with the enclosure as the enclosure will usually be common
with the pole supporting it (basically earth ground).
A. Where bulkhead (black phantom) antennas are used, the inner surface, outer surface, and inner wall of the hole drilled,
should be isolated from the antenna. Use the rubber washers supplied by manufacturer to isolate the antennas from the
enclosures (use thickest washer on exterior side of enclosure).
B. Where external antennas, such as omni-directional and yagi, are used, a polyphaser is typically used. The actual connection
between lightening arrestor and antenna cable should be isolated. The lightening arrestor itself has its own lug designed to
be connected to earth ground.
• Once all wiring and grounding recommendations have been followed it is important to test the ground resistance at the
grounding rod to assure a good ground. The most effective grounding method is direct connection to earth ground with
minimal impedance.
An impedance of less than 5 Ohms recommended.
• For more details on proper grounding electrodes and grounding electrode conductors, consult the National Electrical Code.
CAUTION: Ensure field wiring connections are in accordance with Article 504 of the National Electrical Code, ANSI/NFPA70.
For more details on proper grounding electrodes and grounding electrode conductors, consult the National Electrical Code.
Using a small screwdriver or pin, depress
reset button for at least 1 seconds to
reset DH2 hardware.
Connect PC to DH2 using
Gateway Configuration Cable
and USB to Serial Adapter.
