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 LCP200 instruction manual (D104296X012), available from your Emerson sales office or Fisher.com Always refer to the nameplate itself to identify the appropriate certification. LCP200 instruments with an IIC rating may have different hardware than IIB-rated instruments; be sure to order the appropriately rated instrument based on your application and wiring practices.
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.
Intrinsically Safe
Specific Conditions of Use
- Install the unit in the area of low risk from mechanical hazards. To prevent the risk of electrostatic sparking, the non-metallic surface shall be cleaned with a damp cloth.
Notes
Ambient temperature rating: -40°C ≤ Ta ≤ +65°C
- Install per drawing GG55194, shown in Figures 1, 2, 3, and 4, as indicated on the nameplate.
- Substitution of components may impair intrinsic safety.
- The enclosure contains non-metallic enclosure parts. To prevent the risk of electrostatic sparking, the non-metallic surface shall be cleaned with a damp cloth.
- Refer to table 1 for approval information.

THE INTRINSIC SAFETY ENTITY CONCEPT ALLOWS THE INTERCONNECTION OF TWO APPROVED INTRINSICALLY SAFE DEVICES, WITH ENTITY PARAMETERS NOT SPECIFICALLY EXAMINED IN COMBINATION AS A SYSTEM WHEN: Uo Ui, Io Ii, Co Ci + Cable, Lo Li + Liable, Po Pi. DUST-TIGHT SEAL MUST BE USED WHEN INSTALLED IN DUST-PROTECTED ENVIRONMENTS. EACH CONNECTION BETWEEN THE LCP200 AND THE ASSOCIATED INTRINSICALLY SAFE APPARATUS SHALL BE SEPARATELY SHIELDED FROM THE OTHER CONNECTIONS. WHEN CALCULATING THE ENTITY COMBINATIONS THAT INCLUDE THE DVC6000/DVC6200, THE SUMMATION OF THE Ci + Cable AS WELL AS THE Li + Lcable FOR THE DVC6000/DVC6200 AND THE LCP200 SHALL BE USED. ASSOCIATED APPARATUS MANUFACTURERS’ INSTALLATION DRAWINGS MUST BE FOLLOWED WHEN INSTALLING THIS EQUIPMENT.

NOTES
- FOR Ex ia APPLICATIONS THE FOLLOWING INFORMATION SHALL BE OBSERVED:
- THE OVERALL GAS GROUP RATING OF THE INTRINSICALLY SAFE CIRCUIT WILL BE THE 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 GROUP RATING OF IIB.
- 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 LEVEL OF “ib”.
- THE LOWEST PERMISSIBLE INPUT VOLTAGE (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). THE SUM OF THE MAX UNPROTECTED CAPACITANCE (Ci) AND MAX UNPROTECTED INDUCTANCE (Li), INCLUDING THE INTERCONNECTED CABLING CAPACITANCE (Cable) AND CABLING INDUCTANCE (Liable), MUST BE LESS THAN THE ALLOWABLE CAPACITANCE (Ca) AND INDUCTANCE (La) DEFINED BY THE ASSOCIATED APPARATUS. IF THE ABOVE CRITERIA ARE MET THAN THE COMBINATION MAY BE CONNECTED.
- INSTALLATION OF THE LCP200 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, OR AT THE LCP200.
- MAXIMUM SAFE AREA VOLTAGE MUST NOT EXCEED 250 VRMS
- THE ENCLOSURE CONTAINS NON-METALLIC ENCLOSURE PARTS. TO PREVENT THE RISK OF ELECTROSTATIC SPARKING, THE NON-METALLIC SURFACE SHALL BE CLEANED WITH A DAMP CLOTH.

Explosion-proof
Specific Conditions of Use
- The enclosure contains non-metallic enclosure parts. To prevent the risk of electrostatic sparking, the non-metallic surface shall be cleaned with a damp cloth.
- The flameproof joints of the equipment are not intended to be repaired. Consult the manufacturer if repair of the joints is necessary.
- The electronics compartment rear cover is assembled and torqued at the factory and is not to be removed by the end user.
- Consult the manufacturer for genuine replacement terminal cover fasteners. The fasteners are 316 stainless steel, bolt class A4-70, sized M6 x 1 mm x 15 mm.
