Installation must be in accordance with the National Electrical Code (NFPA 70, Article 504), ANSI/ISA-RP12.6, and the manufacturer’s instructions. If the electrical parameters of the cable used are unknown, the following values may be used: Capacitance - 60 pF/ft; Inductance - 0.20 µH/ft. Barrier bus must be insulated from other grounded metal. Use DIN Rail Mounting Kit, Allen-Bradley #64-136. Maximum nonhazardous area voltage must not exceed 250V. 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. No revision to drawings without prior UL approval. 1 Earth Ground (less than 1 ohm) Gnd GndInstallation Instructions Original Instructions Intrinsically Safe Sensor Catalog Numbers 42DTB- 5500, 42DRU- 5500, 42DRU- 5700, 42DRP- 5500,
