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

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.

Apparatus connection:

D The HART COMM terminals (WP1-WP2) can be only connected to intrinsically safe certified equipment.

D The external power terminal (J5) can be only connected to associated intrinsically safe certified equipment.

These combinations 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.
