5.1 Notes on Wiring
IMPORTANT
•
Apply a waterproofing sealant to the threads
of the connection port. (It is recommended
that you use non-hardening sealant made of
silicon resin for waterproofing.)
•
Lay wiring as far away as possible from
electrical noise sources such as large
transformers, motors and power supplies.
•
Remove the wiring connection dust-caps
before wiring.
• When you open the front panel, pay great
attention to the environmental conditions
in order to prevent dust and water droplets
entering inside the product.
• To run wiring to the sensor, pay sufficient
attention to the wiring parameters described
in section 2.6 “Installation of an Explosion
Protected Instrument.”
•
To prevent electrical noise, the signal cable
and the power cable must not be housed in
the same conduit.
NOTE
•
When wiring where the ambient temperature
is high or low, use the cable or wire that
appropriate to that place.
•
When the maximum operating temperature
is more than 60°C, use the cable of 85°C or
higher temperature rating.
5.2 Cable Selection
For wiring the Modbus device and the FN310, use a
shielded multi-core cable of AWG24 to 14.
Applicable Cables
Cables for industrial equipment such as;
• Control cables: JIS C 3401
When using SECOM, refer to subsection 9.1.1
“Cable Selection”.
Use the following grounding cable.
Applicable Cables
Insulated cables for industrial equipment such as;
• 600V polyvinyl chloride insulated wires (IV): JIS
C3307
• Polyvinyl chloride insulated wires for electrical
apparatus (KIV): JIS C3316
• 600V grade heat-resistant polyvinyl chloride
insulated wires (HIV): JIS C3317
• Heartproof vinyl insulated wires VW-1 (UL
1015/UL 1007)
Wire size
• Core: AWG14 to 13 (2 mm
2
to 2.6 mm

)
Termination
• Use a ring tongue terminal for M4 terminals:
with an insulation sleeve
