ATEX 

STD5000 and STD6000 IS operation 

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: 

U

i

 30Vdc 

I

i

 100mA 

P

STD6000 flame proof operation 

Refer to the STD6000 label in 

Figure C–2

In accordance with the exclusion of EN 60079-1-2007 clause 15.4.3.2.2 
for enclosures containing sinters and with volumes above 0.1 L, the 
STD6000 converter shall not be used in the presence of carbon disulphide. 

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.

 

A suitably certified flame proof gland. 

Warning  

Parallel thread glands should not be inserted directly into the 

tapered thread conduit entry without the use of a suitably certified flame 
proof ½-inch NPTF-to-metric adapter.
