⑨Check the set temperature range. Press the (F3)
key. HART communication is OFF.
• For connecting the power, use a crimp terminal
(M3.5, max. 7.2mm).
• The connection of this unit should be separated from
the power line and high voltage line in order to prevent
inductive noise.
• Install a power switch or a circuit breaker to supply or cut
off the power.
• Switch or circuit breaker should be installed nearby
users for convenient control.
• Do not use this unit near the high frequency instruments
(high frequency welding machine & sewing machine,
large capacity SCR controller).
• Installation environment.
①Indoor / Outdoor
②Altitude max. 2,000m
③Pollution degree 2
④Installation category Ⅱ
• Use the veried explosion-proof electric connection
(cable gland or sealing tting)
(explosion proof standard: over Ex d IIC T6,
IP rating: over IP67 protection structure).
• Use the dedicated external terminal for earth. For
connecting earth, use a spring washer and earth cable
which is over 4mm2.
• We are not responsible for any damages and claims
for careless. Must read the cautions for your safety
and using.
• This explosion-proof unit is certied and the same
specications which is reported to Korea Gas Safety
Corporation.
• If there are any problems with the unit, contact the
head ofce.
• Failure to follow these instructions may result in
product damage.
