Special Conditions for Safe Use (X):
1. If the equipment is fitted with an optional 90V transient suppressor, it
is incapable of withstanding the 500V 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.
3. The equipment contains thin wall diaphragms. The installation,
maintenance and use shall take into account the environmental
conditions to which the diaphragms will be subjected. The
manufacturer's instructions for installation and maintenance shall be
followed in detail to assure safety during its expected lifetime.
