7.7 Grounding
Grounding is always required for the proper
operation of transmitters. Follow the domestic
electrical requirements as regulated in each
country. For a transmitter with a built-in lightning
protector, grounding should satisfy ground
resistance of 10Ω or less.
Ground terminals are located on the inside and
outside of the terminal box. Either of these terminals
may be used.
