Enclosure is manufactured from aluminum alloy. In rare cases, ignition
sources due to impact and friction sparks could occur. This shall be
considered when equipment is installed in locations that specifically require
Group II, Category IG equipment.
Equipment may be used in Zones 0, 1, and 2 with flammable gases and
vapors with temperature classes T1, T2, T3, and T4. Installation must be
in accordance with applicable code of practice (e.g. EN 60079-14).
Equipment may also be used in the presence of explosive dust atmospheres
in Zones 20, 21, and 22. Installation must be in accordance with applicable
codes of practice (e.g. EN 61241-14). Be sure to apply the required safety
margins for temperature.
The equipment must be connected to a suitably certified ATEX barrier
whose parameters must be compatible with the following electrical
parameters:

Equipment is supplied with a ½-inch NPTF (tapered) thread for electrical
connections, which shall be as follows:
1.
An approved metallic conduit incorporating a stopper box, or
2.
