•Follow instructions in 'Cautions during Use'.
Otherwise, it may cause unexpected accidents.
•Power supply should be insulated and limited voltage/current or Class 2, SELV power
supply device.
•Keep away from high voltage lines or power lines to prevent inductive noise.
Do not use near the equipment which generates strong magnetic force or high frequency noise.
•Install a power switch or circuit breaker in the easily accessible place for supplying or disconnecting the power.
• The explosion-proof standard of this unit is Ex d IIC T6, protection structure of this unit is
IP67 and the range of max. surface temperature is below 85℃.
Use the veried explosion-proof electric connection (cable gland or sealing tting)
•This unit may be used in the following environments.
①Indoors (in the environment condition rated in 'Specications')
②Altitude max. 2,000m
③Pollution degree 2
④installation Category II
The explosion-proof unit is certied and the same specications which is reported to Korea Gas Safety Cor-
poration. (This unit is manufactured following by the announcement 2013-54 of Ministry of Employment and
Labor of Korea.)
