NOTES:
1. ANY CSA / FM INTRINSICALLY SAFE BARRIER / POWER SUPPLY, WITH ITS OUTPUT
VOLTAGE (Uo) NOT EXCEEDING 30 V AND ITS OUTPUT CURRENT (Io) LIMITED BY
LOAD RESISTANCE (Ro); SUCH THAT Io = Uo / Ro, DOES NOT EXCEED 120 mA
2. APPROVED DUST-TIGHT AND WATER-TIGHT CONDUIT SEALS ARE REQUIRED
FOR CLASS II, DIV.1, Gr. E, F, G AND OUTDOOR NEMA 4X/TYPE 4X LOCATIONS
3. THE MAXIMUM VOLTAGE OF THE NON-INTRINSICALLY SAFE APPARATUS
MUST NOT EXCEED 250 V rms.
4. UNDER THE ENTITY EVALUATION CONCEPT, THE LR 200 HAS THE
FOLLOWING:
Ui = 30 VOLTS D.C.
Ci = 3.6 nF
5. SUBSTITUTION OF COMPONENTS MAY IMPAIR INTRINSIC SAFETY.
6. INSTALL PER NEC / CEC
7. USE SUPPLY WIRES RATED FOR 10 ° ABOVE.
8. EXTERNAL BONDING HUBS ARE REQUIRED WHEN BOTH CONDUIT ENTRIES ARE USED.
THE ENTITY EVALUATION CONCEPT IS A METHOD USED TO DETERMINE
ACCEPTABLE COMBINATIONS OF INTRINSICALLY SAFE APPARATUS AND
CONNECTED ASSOCIATED APPARATUS THAT HAVE NOT BEEN
INVESTIGATED IN SUCH COMBINATION.
ENTITY CONCEPT DEFINITION: THE ENTITY CONCEPT ALLOWS THE INTERCONNECTIONS OF INTRINSICALLY
SAFE APPARATUS TO ASSOCIATED APPARATUS NOT SPECIFICALLY EXAMINED IN SUCH COMBINATIONS.
THE CRITERIA FOR INTERCONNECTION IS THAT THE VOLTAGE AND CURRENT WITH INTRINSICALLY SAFE
APPARATUS CAN RECEIVE AND REMAIN INTRINSICALLY SAFE, CONSIDERING FAULTS, MUST BE EQUAL OR
GREATER THAN THE VOLTAGE (Uo) AND CURRENT (Io) LEVELS WHICH CAN BE DELIVERED BY
THE ASSOCIATED APPARATUS, CONSIDERING FAULTS AND APPLICABLE FACTORS. IN ADDITION, THE MAX.
UNPROTECTED CAPACITANCE (Ci) AND INDUCTANCE (Li) OF THE INTRINSICALLY SAFE APPARATUS, INCL.
INTERCONNECTING WIRING, MUST BE EQUAL OR LESS THAN THE CAPACITANCE AND INDUCTANCE WHICH
CAN BE SAFELY CONNECTED TO THE ASSOCIATED APPARATUS.
