 EQUIPMENT SHALL BE INSTALLED IN ACCORDANCE WITH THE CANADIAN ELECTRICAL CODE (CEC) PART 1:
 BARRIERS MUST BE CSA APPROVED WITH ENTITY PARAMETERS AND ARE TO BE INSTALLED IN
ACCORDANCE WITH THE MANUFACTURER'S I.S. INSTALLATION INSTRUCTIONS.
 THE ENTITY CONCEPT ALLOWS INTERCONNECTION OF INTRINSICALLY SAFE APPARATUS TO ASSOCIATED
APPARATUS, NOT SPECIFICALLY EXAMINED IN SUCH COMBINATION. THE CRITERIA FOR INTERCONNECTION IS
THAT THE VOLTAGE (Vmax) AND THE CURRENT (Imax) OF THE INTRINSICALLY SAFE APPARATUS MUST BE
EQUAL TO OR GREATER THAN THE VOLTAGE (Voc) AND CURRENT (Isc) 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 INTERCONNECTING WIRING, MUST BE LESS THAN
THE ALLOWABLE CAPACITANCE (Ca) AND INDUCTANCE (La) DEFINED BY THE ASSOCIATED APPARATUS. IF
THESE CRITERIA ARE MET, THEN THE COMBINATION MAY BE CONNECTED.
FORMULAS - Vmax > Voc, Imax > Isc, Ci + Ccable < Ca, Li + Lcable < La
 ENTITY PARAMETERS FOR EACH I.S. CIRCUIT ARE AS FOLLOWS:
 WHERE MULTIPLE IS CIRCUITS ARE USED:
 EACH I.S. CIRCUIT MUST BE SHIELDED TWISTED PAIR CABLE.
 I.S. CIRCUITS MUST ENTER ENCLOSURE VIA CONDUIT ENTRIES
AS SPECIFIED IN DETAIL 1.
 CABLE INSULATION AND SHIELD MUST EXTEND TO WITHIN
PARTITIONED AREA (SEE DETAIL 1).
 XMTR, LS1, AND LS2 CIRCUITS ARE OPTIONAL.
 IF HAND‐HELD COMMUNICATOR OR MULTIPLEXOR IS USED, IT MUST
BE CSA CERTIFIED WITH ENTITY PARAMETERS AND INSTALLED PER
THE MANUFACTURER'S CONTROL DRAWING.

Special Conditions of Use
Intrinsically Safe, Non‐Incendive
The apparatus enclosure contains aluminum and is considered to constitute a potential risk of ignition by impact or
friction. Care must be taken into account during installation and use to prevent impact or friction.
Refer to figure 26 for a typical DVC2000 FM approval nameplate and figure 27 for installation drawing GE10683.
