l Wiring of antenna extension cable
1. Use the provided antenna extension cable to connect the antenna connector with the re-
mote antenna. Tighten the connector of the antenna extension cable with a torque of 2 to 3
N∙m. Refer to the specification about the limitation of bend radius when fixing or wiring.
2. When using two antenna extension cables, the provided arrestor should be inserted be-
tween these cables.
3. Before the wiring work, confirm the polarities (male/female) of the connectors of antenna,
antenna extension cable, and arrestor.
Tighten the connector of the antenna extension cable with a torque of 2 to 3 N∙m.

l Ground wiring of arrestor for antenna extension cables
To connect two antenna extension cables, an arrestor for lightning protection is provided. Place
the arrestor between the two antenna extension cables. Connect the grounding cable to the
ground terminal of the arrestor.
Connect the grounding cable to the grounding terminal on the main body. Class D grounding (the
third class grounding) with the grounding resistance of 100 Ω or less is necessary. Do not share
the ground with other devices.
