Special Conditions for Safe Use (X):
1. The apparatus is not capable of withstanding the 500 V insulation test required by
clause 6.3.12 of EN60079-11:2012. This must be taken into account when installing
the apparatus.
2. The enclosure may be made of aluminum alloy and given a protective polyurethane
paint finish; however care should be taken to protect it from impact or abrasion if
located in Zone 0.
3. Some variants of the equipment have reduced markings on the nameplate. Refer to
the Certificate for full equipment marking.
