Dwyer PBLTX - Manual (Page 3)

NOTES:
1. MAX SAFE AREA VOLTAGE NOT TO EXCEED 250 VAC.
2. NO REVISIONS WITHOUT PRIOR UNDERWRITERS LABORATORY APPROVAL.
3. (ENTITY CONCEPT DEFINITIONS)
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 AND
CURRENT WHICH INTRINSICALLY SAFE APPARATUS CAN RECEIVE AND REMAIN INTRINSICALLY SAFE, CONSIDERING FAULTS, MUST BE
EQUAL TO OR GREATER THAN THE VOLTAGE (Voc) AND CURRENT (Isc) LEVELS WHICH CAN BE DELIVERED BY THE
ASSOCIATED APPARATUS. CONSIDERING FAULTS AND APPLICABLE FACTORS. IN ADDITION, THE MAXIMUM UNPROTECTED CAPACITANCE AND
INDUCTANCE (Ci & Li) OF THE INTRINSICALLY SAFE APPARATUS. INCLUDING INTERCONNECTING WIRING. MUST BE EQUAL TO OR LESS THAN
THE CAPACITANCE AND INDUCTANCE WHICH CAN BE SAFELY CONNECTED TO ASSOCIATED APPARATUS.
4. INSTALLATION MUST BE IN ACCORDANCE WITH THE NATIONAL ELECTRICAL CODE (NFPA 70, ARTICLE 504) AND ANSI/ISA-RP12.6.
IMPORTANT! NO REVISIONS WITHOUT
PRIOR UNDERWRITERS LABORATORIES
APPROVAL CAN BE IMPLEMENTED
