Hazardous Area Classifications and Special Instructions for “Safe Use” and
Installation in Hazardous Locations
Certain nameplates may carry more than one approval, and each approval may have unique installation/wiring
requirements and/or conditions of “safe use”. These special instructions for “safe use” are in addition to, and may
override, the standard installation procedures. Special instructions are listed by approval.
Note
This information supplements the nameplate markings affixed to the product and the 4320 instruction manual (D103621X012

INSTALLATION MUST BE IN ACCORDANCE WITH THE NATIONAL WIRING PRACTICES OF THE COUNTRY IN USE.
BARRIERS MUST BE CONNECTED PER MANUFACTURE'S INSTALLATION INSTRUCTIONS.
INTRINSICALLY SAFE APPARATUS MAY BE CONNECTED TO ASSOCIATED APPARATUS NOT SPECIFICALLY
EXAMINED IN SUCH COMBINATION. THE CRITERIA FOR INTERCONNECTION IS THAT THE VOLTAGE (Ui) AND
THE CURRENT (Ii) OF THE INTRINSICALLY SAFE APPARATUS MUST BE EQUAL TO OR GREATER THAN THE
VOLTAGE (Uo) AND CURRENT (Io) DEFINED BY THE ASSOCATED APPARATUS. IN ADDITION, THE SUM OF
THE MAXIMUM UNPROTECTED CAPACITANCE (Ci) AND INDUCTANCE (Li) OF EACH INTRINSICALLY SAFE
APPARATUS, AND THE INTERCONNECTING WIRING, MUST BE LESS THAN THE ALLOWABLE CAPACITANCE (Co)
AND INDUCTANCE (Lo) DEFINED BY THE ASSOCIATED APPARATUS. IF THESE CRITERIA ARE MET, THEN THE
COMBINATION MAY BE CONNECTED.
FORMULAS Ui > Uo
Ii > Io
Ci + Ccable < Co
Li + Lcable < Lo
Pi > Po
RESISTANCE BETWEEN BARRIER GROUND AND EARTH GROUND MUST BE LESS THAN ONE OHM.
IF HAND-HELD COMMUNICATOR OR MULTIPLEXER IS USED, IT MUST BE APPROVED WITH ENTITY
PARAMETERS AND INSTALLED PER THE MANUFACTURER'S CONTROL DRAWING.
WARNING
THE APPARATUS ENCLOSURE CONTAINS ALUMINUM AND IS CONSIDERED TO CONSTITUTE
A POTENTIAL RISK OF IGNITION BY IMPACT OR FRICTION. AVOID IMPACT AND FRICTION
DURING INSTALLATION AND USE TO PREVENT RISK OF IGNITION.
