               Dual Sinking Output Wiring

   Factory Mutual Installation Notes:
       Installation must be in accordance with the National Electrical CodeR (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.
       The wiring between each Inductive Proximity Sensor and its corresponding channel of the dual-channel barrier is a separate intrinsically safe circuit. Each of the two separate
       intrinsically safe circuits shall be in separate cables or shall be separated from each other as specified in NEC 504--30. The supply return conductors may be connected at the
       barrier’s grounding terminal.
       The Barrier bus must be insulated from other grounded metal. Use DIN Rail Mounting Kit, Rockwell Automation #64--136.
       The maximum nonhazardous location voltage must not exceed 250V AC or DC.
       Barriers are not required for Division 2 (31.5V DC max.). Division 2 applications must be installed in accordance with the NEC.
       WARNING: Substitution of components may impair Intrinsic Safety.
       No revision to drawing without prior FMRC approval.

   Canadian Standards Association Installation Notes:
      Installation must be in accordance with the Canadian Electrical Code (Part I), 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.
      The wiring between each Inductive Proximity Sensor and its corresponding channel of the dual-channel barrier is a separate intrinsically safe circuit. Each of the two separate
      intrinsically safe circuits shall be in separate cables or shall be separated from each other as specified in CEC. The supply return conductors may be connected at the barrier’s
      grounding terminal.
      The Barrier bus must be insulated from other grounded metal. Use DIN Rail Mounting Kit, Allen-Bradley #64--136.
      The maximum nonhazardous location voltage must not exceed 250V AC or DC.
      Barriers are not required for Division 2 (31.5V DC max.). Division 2 applications must be installed in accordance with the CEC.
      In Division 2 applications without barriers observe the following warnings:
      WARNING: EXPLOSION HAZARD. Do not disconnect equipment unless power has been switched off or the area is known to be nonhazardous.                                  75001- 437- 01(C)
      WARNING: Substitution of components may impair Intrinsic Safety.                                                                                                       March 1998

down time due to improper wiring,
shorts, radio frequency interference,
line spikes, and many other causes.




  This distance varies with current line
  amperage. See page 2--10 of the Introduction
  section to determine the minimum distance for
  your application.

 Unshielded proximity sensors require a metal-free zone around the sensing face. Any metal immediately opposite the sensing face should be no closer than
 three times the rated nominal sensing distance of the sensor.

Each sensor is housed in a
self-extinguishing glass-reinforced
polyester body. Special hazardous
location models are available which
meet Division 2 enclosure standards in
Classes I, II, and III (see specifications).
Switch constructions include top and
side sensing models. The side-sensing
head can be rotated in 90° increments
to sense in four directions. These
devices are available with a threaded
conduit opening, conduit coupler, 3-pin
mini connector, 3-pin micro connector,
or pre-wired cable.
