NOTES

 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 or Ui), THE

CURRENT (Imax or Ii), AND THE POWER (Pmax or Pi) OF THE INTRINSICALLY SAFE APPARATUS MUST BE EQUAL TO OR GREATER THAN

THE VOLTAGE (Voc or Uo), AND THE CURRENT (Isc or Io), AND THE POWER(Po) DEFINED BY THE ASSOCIATED APPARATUS. IN

ADDITION, THE SUM OF THE MAX UNPROTECTED CAPACITANCE (Ci) AND MAX UNPROTECTED INDUCTANCE (Li), INCLUDING THE

INTERCONNECTING CABLING CAPACITANCE (Ccable) AND CABLING INDUCTANCE (Lcable) MUST BE LESS THAN THE ALLOWABLE

CAPACITANCE (Ca) AND INDUCTANCE (La) DEFINED BY THE ASSOCIATED APPARATUS. IF THE ABOVE CRITERIA IS MET, THEN THE

COMBINATION MAY BE CONNECTED.

Vmax or Ui  Voc or Uo Imax or Ii  Isc or Io Pmax or Pi  Po Ci + Ccable ≤ Ca Li + Lcable ≤ La

 INSTALLATION MUST BE IN ACCORDANCE WITH THE CANADIAN ELECTRICAL CODE (CEC) AND ANSI/ISA RP12.6.

 MAXIMUM SAFE AREA VOLTAGE SHOULD NOT EXCEED 250 Vrms.

 RESISTANCE BETWEEN INTRINSICALLY SAFE GROUND AND EARTH GROUND MUST BE LESS THAN ONE OHM

 LOOPS MUST BE CONNECTED ACCORDING TO THE BARRIER MANUFACTURER’S INSTRUCTIONS.

 IF HAND-HELD COMMUNICATOR OR MULTIPLEXER IS USED, IT MUST BE CSA APPROVED WITH ENTITY PARAMETERS AND

INSTALLED PER THE MANUFACTURER’S CONTROL DRAWINGS.
