CONDITIONS OF CERTIFICATION:
The Process Gas Monitor, Model PIRVOL, has a threaded wire feed through incorporating flying leads. This feed
through is to be screwed into the cable entry opening of a suitable certified (Ex ‘d’ or Ex ‘e’) enclosure in which the
flying leads are to be terminated.
In order to maintain the Ingress Protection rating IP66, the back end of the Process Gas Monitor, Model PIRVOL, with
the flying leads is to be screwed into a suitable certified flameproof enclosure with an Ingress Protection rating of at
least IP66.
