Special Conditions for Safe Use (X):
1. When fitted with a transient suppression terminal block, the
Rosemount 2088 is incapable of passing the 500 V isolation test. 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 or abrasion if located in a Zone 0 environment.
