MONITOUCH V9 series: Introducing V9xxxixD-U800

About Explosion Proof

MONITOUCH V9 series (non-incendive model) is classified as “Type n” and it complies with Zone2.

What is explosion-proof equipment?

In hazardous locations where flammable or pyrophoric gases are released, such as oil refineries and chemical plants, it is necessary to use explosion-proof equipment that is equipped with measures to prevent ignition and explosion. International Electrotechnical Commission (IEC)*1 introduced IECEx,
a system for testing compliance with explosion-proof equipment standards, in 1996. In hazardous locations, explosion-proof equipment that complies with the standard must be used.

What is explosion-proof equipment?

In atmospheres where flammable or pyrophoric gases may be present, explosion-proof equipment should be used.

*1 International Electrotechnical Commission (IEC) is the organization for the preparation
and publication of international standards for all electrical, electronic and related technologies.
There are 89 member countries worldwide (as of October 2020).

What are hazardous areas?

Hazardous areas are classified into 3 zones based on the explosion risk by IEC60079.

An area in which an explosive gas atmosphere is present continuously or for long periods.
(Above the liquid level of combustible gas, etc.)
An area in which an explosive gas atmosphere is likely to occur occasionally in normal operation.
(Gas and steam discharge areas and near injection openings)
An area which becomes hazardous in case of an accident or some unusual operating condition and is close to Zone1.

MONITOUCH V9 Series: Non-incendive (Type n) Model *2


MONITOUCH V9 series (non-incendive model) is complied with the IECEx international standard, Taiwan TS Mark, and Korea KCs certification *3.

Corresponding certification


Install in an explosion-proof certified enclosure with appropriate explosion-proof construction, such as
Ex ec IIC Gc, Ex eb IIC Gc, and Ex nA IIC Gc.
Each country may have its own certification system (explosion-proof, EMC, etc.). Please check the
certification system of each country before using the product.
