About explosion-proof
•
Do not modify or change the circuit, structure, etc.
•
When using the gas detector in a hazardous area, take the following countermeasures for
preventing dangers resulting from electrostatic charges.
(1) Wear anti-static clothes and conductive shoes (anti-static work shoes).
(2) For indoor use, use the gas detector while standing on a conductive work floor (with a
leakage resistance of 10 MΩ or less).
•
Replace the batteries in a non-hazardous area.
•
The specifications of the gas detector are as follows:
Power supply: 6.0 VDC (LR6, manufactured by TOSHIBA, 4 pcs)
Ambient temperature: -20 - +50ºC
•
The explosion-proof class of the gas detector is as follows:
Ex ia IIC T4 (Japan Ex)
II1G Ex ia IIC T4 Ga (ATEX explosion-proof directive)
Ex ia IIC T4 Ga (IECEx explosion-proof directive)
•
The protective class of the case to be explosion-proof is IP20.
IP20 is a protection class to be explosion-proof. The IP protection class is compliant to IP67
level by factory default.
