ATEX Hazardous Area Approvals
Fisher™4320 Wireless Position Monitor
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),
available from your Emerson sales office, Local Business Partner, or www.Fisher.com.
Always refer to the nameplate itself to identify the appropriate certification.
WARNING
Failure to follow these conditions of “safe use” could result in personal injury or property damage from fire or explosion,
and area re‐classification.

Special Conditions of Use
The apparatus shall not be subjected to mechanical impacts or friction.
The piezo valve can be used with natural gas as control fluid provided that no gas-air mixtures are present in the
pressure system.
HART communication terminals (WP1-WP2) must be only connected to certified intrinsic safety equipment and this
combination must be compatible regarding intrinsic safety rules.
Battery Sourced Power Module:
The apparatus can only be powered with a module type GE57654X012 or GE57655X012
External Power:
The apparatus may be powered externally via external power module GE61615X012
Install per control drawing GE59530 which includes intrinsic safety information.
Figure 1. Installation Drawing Notes; See Figure 2 for Battery Module Assembly & Figure 3 for External Power Option
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.
