Notes:
– Installation must be in accordance with the National Electrical Code ®
(NFPA 70, Article 504), ANSI/ISA--RP12.6, and the manufacturer’s instructions.
— Barrier entity parameters: Voc 29.5V; Isc 107mA; Ca Ccable; La Lcable; recommended barriers are indicated on the above wiring diagram.
˜ If the electrical parameters of the cable used are unknown, the following values may be used: Capacitance -- 60pF/ft.; IInductance -- 0.20 H/ft.
™ Barrier bus must be insulated from other grounded metal. Use DIN Rail Mounting Kit, Allen-Bradley #64--136.
š Maximum nonhazardous area voltage must not exceed 250V.
› Barriers are not required for Division 2 (29.5V DC max.). Division 2 applications must be installed in accordance with the National Electrical Code
®
.
œ An approved dust tight seal is required for Class II, III applications.
 The output circuits of Zener Diode Barriers shall be in separate cables or separated from each other per NEC 504--30.
ž No revision to drawing without prior FMRC and UL approval.
