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 1.2 N•m. The minimum bend 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 fi xing in the state maintained for a long
period should be more than 100 mm.

CAUTION
• Use the dedicated remote antenna cable
provided by Yokogawa as accessories for
FN110.
• The remote antenna cable and other cables
should not be bundled together.
• Remove the battery pack before installing
FN110. Refer to subsection 8.3 “Replacing
the Battery Pack” for the battery pack
removing.

Vertical Connection Wiring
The cable gland is not included. Prepare a cable
gland with a fl at 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, fi x the hexagonal
shape part by tool and tighten the cable gland as
shown in Figure 5.6.
