6.1.2 Mounting External Antenna and

Wiring Antenna Extension Cable

6.1.2.1 Mounting of External Antenna

Mount the external antenna at the proper location

according to the wireless environment described

in 2.4 Selecting the Installation Location. The

mounting to the pipe such as 50 mm (2-inch) pipe

needs to secure the enough strength to endure a

strong wind, vibration and so on. The antenna must

be mounted vertically.

Fixing of External Antenna

Fix an external antenna appropriately using the

bracket provided as the external antenna option to

50 mm (2-inch) pipe.

Mounting Procedure of External

Antenna

1. Fix the bracket by U-bolt and nut to 50 mm (2-

inch) pipe.

2. Fix the antenna extension cable to the bracket

1 using the provided nut with a torque of 6 to 7

N∙m as shown in the Figure 6.3 above. Use the

nut which is attached to the antenna extension

cable.

3. Screw the antenna into the antenna connector

of the antenna extension cable on the bracket

1.

Tighten the antenna connector with a torque of

2 to 3 N∙m.

4. Protect the connection as necessary. For

details of the protection, see “6.1 Mounting

Antenna and Wiring.”

6.1.2.2 Wiring of Antenna Extension Cable

1. Use the provided antenna extension cable

to connect the antenna connector with the

external antenna. Tighten the connector of the

antenna extension cable with a torque of 2

to 3 N∙m. The minimum bending radius while

checking the wiring position should be more

than 200 mm.

2. When using two extension cables, the provided

arrester should be inserted between these

cables.

3. Before the wiring work, confirm the polarities

(male/female) of the connectors of antenna,

extension antenna cable, and arrester. Tighten

the connector of the antenna extension cable

with a torque of 2 to 3 N∙m.

4. Protect the connectors of antenna, extension

antenna cable, and arrester as necessary. See

“6.1 Mounting Antenna and Wiring.”

5. Fix the extension antenna cable to the

appropriate structure to protect the cable from

the vibration, wind, and so on. The minimum

bending radius for fixing in the state maintained

for a long period should be more than 80 mm.
