INSTALLATION MUST BE IN ACCORDANCE WITH THE NATIONAL WIRING PRACTICES OF THE COUNTRY IN USE.

BARRIERS MUST BE CONNECTED PER MANUFACTURER’S INSTALLATION INSTRUCTIONS.

3 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
INTERCONNECTING WIRING, MUST BE LESS THAN THE ALLOWABLE CAPACITANCE (Co)
AND INDUCTANCE (Lo) DEFINED BY THE ASSOCIATED APPARATUS. IF THESE
CRITERIA ARE MET, THEN THE COMBINATION MAY BE CONNECTED.
