CAUTION
• To maintain a good connection between
the modules, protect the connector from
the corrosive atmosphere by the following
treatment.
1. Clean the connection to be protected.
2. Wind the butyl rubber self-bonding tape
around the connection. See the manual
of the tape about the winding.
3. To protect the butyl rubber self-bonding
tape from the environment such as
ultraviolet rays and so on, wind vinyl tape
(or a vinyl type self-bonding tape) on it.
4. When the tape is necessary, prepare
appropriate tape for the installing
environment.
Do not cover the nameplate by the tapes.
• When a remote antenna cable is used for
installing FN110, refer to subsection 5.3
“Installation and Connection of FN110”.
• Remove the battery pack before installing
FN110. Refer to subsection 8.3 “Replacing
the Battery Pack” for the battery pack
removing.
• When installing FN110, fi x the FN110 by
tightening the lock nut. Screwing by holding
the FN110 housing may cause failure such
as cable disconnection. The same manner
should be taken when removing the FN110.

To directly install FN310 to the HART device,
follow the procedure below.
1) Screw the horizontal connection male thread
to the electrical connection port of the HART
device.
2) Pass the cable from the HART device to the
electrical connection port of the FN310.
3) Attach the electrical connection port of the
FN310 and horizontal connection male thread
so as not to pinch the cable. Then, secure using
a clamp.
IMPORTANT
When a Horizontal connection 1/2 NPT male
thread is used, apply a water proofi ng sealant
to the threads of the connection port. (It is
recommended that you use non-hardening
sealant made of silicon resin for waterproofi ng.)
