6.1.2.3 Mounting of Surge Protective
Device and Wiring
Mount an surge protective device between the
extension cables and connect the grounding cable
to the grounding terminal of the surge protective
device as required.
Connect the grounding cable to the grounding
terminal on the transmitter body. Class C grounding
with the grounding resistance of 10 Ω or less is
necessary. Do not share the ground with other
devices.

6.2 Grounding
When using the antenna extension cable with an
arrestor, Class C grounding with the grounding
resistance of 10 Ω is required. Always ground the
transmitter case in accordance with national and
local electrical codes. The most effective transmitter
case grounding method is a direct connection to
earth ground with minimal impedance.
IMPORTANT
Proper grounding is necessary to maintain the
function and performance of this product. When
the grounding is inadequate, the equipment may
be damaged.
Refer to TI 01W01A58-01EN for details of
grounding method and precautions.
• Use a grounding cable of AWG 14 (2 mm
2
)
or more between the grounding electrode
and the grounding terminal of this product,
and connect with the shortest route.
• Select the grounding cable that has a
structure of adequately protects against
mechanical damage, chemical or electrical
degradation, electrodynamic force and
thermodynamic force for connection of the
grounding electrode and the ground terminal
of this product.
CAUTION
Grounding is required for safe operation.
