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.
