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 DVC2000 quick start guide (D103203X012
and instruction manual (D103176X012
Always refer to the nameplate itself to identify the appropriate certification.
), available from your Emerson sales office, Local Business Partner, or 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.
Conditions of Certification
Intrinsically Safe
This equipment shall be connected in accordance with the manufacturer's installation instructions (drawing GE14581,
figure 2) to intrinsic safety barriers that satisfy the following parameters for each set of terminals.
Main 4-20 mA: Ui = 30 V, Ii = 130 mA, Pi = 1W, Li = 0.55 mH, Ci = 10.5 nF
XMTR circuit: Ui = 28 V, Ii = 100 mA, Pi = 1W, Li = 0 mH, Ci = 5 nF
Limit Switch 1 (LS1): Ui = 16 V, Ii = 76 mA, Pi = 1W, Li = 0 mH, Ci = 5 nF
Limit Switch 2 (LS2): Ui = 16 V, Ii = 76 mA, Pi = 1W, Li = 0 mH, Ci = 5 nF
Refer to figure 1 for a typical DVC2000 IECEx approval nameplate.

INSTALLATION MUST BE IN ACCORDANCE WITH THE NATIONAL WIRING PRACTICES OF THE
COUNTRY IN USE.
BARRIERS MUST BE CONNECTED PER MANUFACTURER'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 ASSOCIATED APPARATUS. IN
ADDITION, THE SUM OF THE MAXIMUM UNPROTECTED CAPACITANCE (Ci) AND
INDUCTANCE (Li) OF EACH INTRINSICALLY SAFE APPARATUS, AND THE
HAZARDOUS LOCATION NON‐HAZARDOUS LOCATION
INTERCONNECTING WIRING, MUST BE LESS THAN THE ALLOWABLE
CAPACITANCE (Co) AND INDUCTANCE (Lo) DEFINED BY THE
ASSOCIATED APPARATUS. IF THESE
ZONE 0, GROUP IIC
CRITERIA ARE MET, THEN THE COMBINATION MAY BE CONNECTED.
