Hazardous Area Classifications and Special Instructions for “Safe
Use” and Installations 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 LCP100 Local Control Panel instruction
manual (D103272X012
Always refer to the nameplate itself to identify the appropriate certification.

), available from your Emerson sales office, Local Business Partner, or at Fisher.com.
WARNING
Failure to follow these conditions of “safe use” could result in personal injury or property damage from fire or explosion, or
area re‐classification.

Special Conditions of Use
1. Install in an area that has a low risk of mechanical damage.
2. Install the cover, tightening the screws evenly in a criss‐cross pattern, such as the one indicated in figure 1, to a
torque of 2.82 N•m (25 lbf•in) to help ensure the cover is properly installed.

NOTES:
1. FOR Ex ia APPLICATIONS THE FOLLOWING INFORMATION SHALL BE OBSERVED.
a) THE POWER SELECTOR SWITCH MUST BE POSITIONED IN THE “LOOP” MODE POSITION.
b) NO WIRING CONNECTIONS SHALL BE MADE TO THE 24 VDC POWER TERMINALS.
c) THE OVERALL GAS GROUP RATING OF THE INTRINSICALLY SAFE CIRCUIT WILL BE LOWEST GAS GROUPING OF ALL APPARATUS FORMING
THE CIRCUIT. FOR EXAMPLE, A CIRCUIT WITH BOTH IIB AND IIC APPARATUS WILL HAVE AN OVERALL CIRCUIT GAS RATING OF IIB.
d) THE LEVEL OF PROTECTION OF THE INTRINSICALLY SAFE CIRCUIT WILL BE THE LOWEST LEVEL OF ALL APPARATUS FORMING THE
CIRCUIT. FOR EXAMPLE, A CIRCUIT WITH BOTH “ia” AND “ib” WILL HAVE AN OVERALL PROTECTION RATING OF “ib”.
2. THE PERMISSIBLE INPUT VOTAGE Ui, INPUT CURRENT Ii AND INPUT POWER Pi OF EACH APPARATUS SHALL BE GREATER THAN OR EQUAL TO THE
OUTPUT VOLTAGE Uo, OUTPUT CURRENT Io, AND OUTPUT POWER Po OF THE ASSOCIATED APPARATUS (BARRIER).
3. INSTALLATION OF THE LCP100 IS SUCH THAT ITS LOOP TERMINALS WILL BE CONNECTED IN PARALLEL WITH OTHER INTRINSICALLY SAFE
APPARATUS LOOP TERMINALS. THE WIRING COMING FROM THE BARRIER INTO THE HAZARDOUS LOCATION MAY BE TERMINATED AT EITHER THE
INTRINSICALLY SAFE APPARATUS, AS SHOWN IN FIGURE 2 OR AT THE LCP100, AS SHOWN IN FIGURE 4.
