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.
• To prevent electrical noise, the signal cable
and the power cable must not be housed in
the same conduit.
5.2 Cable Selection
A dedicated cable is used for connection between
the temperature sensor and the temperature
transmitter.
When a thermocouple is used as the temperature
sensor, a compensation wire that is appropriate for
the type of thermocouple (refer to compensating
cables for IEC584-3 thermocouples) must be used.
When a resistance temperature sensor (RTD) is
used as the temperature sensor, 2-core/3-core/4-
core cable must be used (refer to resistance
thermometer sensor IEC751). In a place where the
cable will be susceptible to the effect of noise, a
shielded cable must be used.
The terminal of the dedicated cable is a 4 mm
screw.
