SAFE AREA OR BY AN APPROVED TERMINAL BOX CERTIFIED
TO EN 60079-0/IEC 60079-0, EN 60079-1/IEC 60079-1, AND EN
60079-31/IEC 60079-31 FOR HAZARDOUS LOCATIONS. THE
EPOXY RESIN SHALL NOT BE SUBJECTED TO A TEMPERATURE
GREATER THAN 125°C (257°F). THE WIRES SHALL BE PROTECTED
AGAINST MECHANICAL DAMAGE, E.G., BY USE OF CONDUIT.

SUITABILITY FOR CLASS I, DIV. 1 LOCATION.
PROOF PRESSURE * LIMITS STATED IN THE LITERATURE
AND ON NAMEPLATES MUST NEVER BE EXCEEDED, EVEN
BY SURGES IN THE SYSTEM. OCCASIONAL OPERATION OF
UNIT UP TO PROOF PRESSURE IS ACCEPTABLE (E.G., START-
UP, TESTING). CONTINUOUS OPERATION SHOULD NOT
EXCEED THE DESIGNATED OVER RANGE ** OR WORKING
PRESSURE RANGE***.
* Proof Pressure - the maximum pressure to which a pressure sen-
sor maybe occasionally subjected, which causes no permanent dam-
age (e.g., start-up, testing). The unit may require re-gapping.
** Over Range Pressure - the maximum pressure to which a pres-
sure sensor may be continuously subjected without causing damage
and maintaining set point repeatability.
*** Working Pressure Range - the pressure range in which two op-
posing sensors can be safely operated and still maintain set point
provided the diff erence in pressure between the low and high sides
does not exceed the designated adjustable range.
