Quick Start Guide
Special Conditions for Safe Use (X):
1. If the apparatus is fitted with optional 90 V transient suppressor, it is not capable of
withstanding the 500 V insulation test required by IEC60079-11. 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.
