5.1.2 Mounting External Antenna and
Wiring Antenna Extension Cable
5.1.2.1 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 5.3 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 “5.1 Mounting
Antenna and Wiring.”
5.1.2.2 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
“5.1 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.
