Special Conditions for Safe Use (X):
1. If the equipment is fitted with an optional 90V transient suppressor, it
is not capable of withstanding the 500 V insulation test required by
ABNT NBR IRC 60079-11. This must be taken into account when
installing the equipment.
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 in zones that require EPL Ga.
