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.
LCP100 Local Control Panel
), 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.

Entity parameters
Refer to drawing GE75327, shown in figure 1, 2, and 3.
Special Conditions for Safe Use
1. The 24 VDC input terminals shall not be used.
2. Under certain extreme circumstances, the plastic enclosure may store an ignition-capable level electrostatic
charge. Precautions shall be taken to prevent the build up of electrostatic charge by charge-generating
mechanisms, e.g. do not rub with a solvent, as indicated on the product nameplate.

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 1 OR AT THE LCP100, AS SHOWN IN FIGURE 3.
