Grounding
A transmitter is typically grounded by installing it on a mast or a cross arm that provides a
good connec
tion to earth ground.
As grounding is provided through the fixing screw (or mounting bolt), it is important that it
makes a good gr
ound connection.
4.5.1 Grounding with Bushing and Grounding Kit
If the surface of the mounting point is painted or has some other finishing that prevents a
good electrical c
onnection, consider using the Bushing and Grounding Kit (222109) and a
cable to ensure ground connection.
Use the Bushing and Grounding Kit to run a cable from the fixing screw to a grounding
point. T
he kit does not include a grounding cable. The minimum grounding conductor size is
4 mm
2
(AWG 11).
1. Assemble the grounding kit so that the connector for the grounding cable is between
the washers and nuts.
1 Connector for grounding cable
2 Abiko connector
3 Washer (2 pcs)
4 Nut (2 pcs)
5 Fixing screw
2. Connect a grounding cable to the connector. Use a 16 mm
2
conductor to achieve a good
ground connection.
3. Remove the transmitter fixing screw.
