5.3.2 Connection of FN110
To install FN110 with remote antenna cable,
follow the procedure below.
Remove the battery pack from FN310 before
connecting the remote antenna cable.
1. Connect the FN110 and the FN310 with the
dedicated remote antenna cable. Tighten the
connector of the remote antenna cable with a
torque of 1 to 1.2 N•m. The minimum bending
radius should be more than 100 mm.
2. Protect the connectors of the FN110 and
remote antenna cable as necessary. For details
of the protection, refer to subsection 4.2.1
“Installation of FN110”.
3. Fix the remote antenna cable to an 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 100 mm.

Wiring Example
The cable gland is not included. Prepare a cable
gland with a flat gasket matching the electrical
connection.
When M20 female is selected for vertical
connection, tighten the cable gland with a torque of
2 N • m. When G 1/2 female or 1/2 NPT female is
selected for vertical connection, fix the hexagonal
shape part by tool and tighten the cable gland as
shown in Figure 5.5.
