 THE NATIONAL ELECTRIC CODE (NEC), NFPA 70, ARTICLE
 504 AND ANSI/ISA RP12.6.
2. CLASS 1, DIV 2 APPLICATIONS MUST BE INSTALLED AS SPECIFIED
 IN NEC ARTICLE 501-4(B). EQUIPMENT AND FIELD WIRING IS
 NON-INCENDIVE WHEN CONNECTED TO APPROVED BARRIERS WITH
 ENTITY PARAMETERS.
3. LOOPS MUST BE CONNECTED ACCORDING TO THE BARRIER
 MANUFACTURERS INSTRUCTIONS.
4. MAXIMUM SAFE AREA VOLTAGE SHOULD NOT EXCEED 250 Vrms.
5. RESISTANCE BETWEEN BARRIER GROUND AND EARTH GROUND
 MUST BE LESS THAN ONE OHM.
6. NORMAL OPERATING CONDITIONS 30 VDC 20 mADC.
7. IF HAND-HELD COMMUNICATOR OR MULTIPLEXER IS USED,
 IT MUST BE FM APPROVED AND INSTALLED PER THE
 MANUFACTURE'S CONTROL DRAWING.
8. FOR ENTITY INSTALLATION (I.S. AND N.I.);
Vmax > Voc, or Vt Ci + Ccable < Ca
Imax > Isc, or It Li + Lcable < La
Pi > Po, or Pt
9. THE APPARATUS ENCLOSURE CONTAINS ALUMINUM AND IS
 CONSIDERED TO CONSTITUTE A POTENTIAL RISK OF IGNITION
 BY IMPACT OR FRICTION. AVOID IMPACT AND FRICTION DURING
 INSTALLATION AND USE TO PREVENT RISK OF IGNITION.
