Special Conditions for Safe Use (X):
1. If the equipment is fitted with an optional 90 V transient suppressor, it is incapable of
withstanding the 500 V isolation from earth test and this must be taken into account
during installation.
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 and abrasion when
located in Zone 0.
