      Overview Manuals Common Applications Product Precautions
      Allen-Bradley 1746-A4 provides the modular backplane and mechanical chassis for an SLC 500 controller or I/O-adapter assembly. It organizes the installed modules within an enclosure-mounted control system.
      • Supports a coordinated processor or I/O adapter and module assembly.
      • Provides the left-side mounting interface for an SLC power supply.
      • Permits cable-linked chassis expansion in an approved SLC 500 layout.
      • Allows unoccupied module positions to be protected with slot fillers.

      Install 1746-A4 in a grounded control enclosure with the specified SLC 500 modules, power supply and interconnect hardware. Follow the cabinet drawing when locating the chassis and routing expansion cables.

      Important Notice: Match the complete 1746-A4 chassis series to the installed system, then inspect the ground bond, mounting alignment, power-supply fit and module seating before energization.

      Important Notice: The first document is an Apter Power exact-model technical reference. The second is the unmodified Rockwell Automation installation publication for the SLC 500 modular chassis.

      1746-A4 local SLC 500 controller chassisHouses the modular SLC processor and its approved I/O selection in an enclosure-mounted control rack.
      1746-A4 I/O adapter chassisProvides a chassis position for a compatible I/O adapter and installed modules in a documented SLC 500 I/O layout.
      1746-A4 linked chassis expansionForms one chassis in a cable-linked SLC 500 assembly when the system design needs additional module positions.
      1746-A4 panel-mounted I/O assemblySupports a grounded cabinet installation with the specified power supply, module population and protective slot fillers.
      Before installing Allen-Bradley 1746-A4, follow Rockwell Automation publication 1746-IN016C-MU-P and verify the cabinet arrangement against the actual chassis and connected hardware.
      1
      Match the complete 1746-A4 catalog and series marking to the approved SLC 500 cabinet design.
      2
      Remove chassis power before fitting or removing the processor, adapter, supply or I/O modules.
      3
      Keep drilling chips and other conductive debris away from installed electronics and the backplane.
      4
      Keep the mounting tabs flat; use suitable shims if the enclosure panel would distort the chassis.
      5
      Bond each chassis individually to the enclosure ground bus by the documented method.
      6
      Fit any specified chassis interconnect cable before attaching the power supply.
      7
      Protect unoccupied module openings with the documented 1746-N2 card-slot filler.
      8
      Record ground continuity, module seating and startup diagnostics before releasing the assembly.

      Technical notes

      Technical notes

      Mount the 1746-A4 chassis flat against the enclosure back panel and bond it to the enclosure ground bus. Install an interconnect cable, if required, before attaching the chassis power supply.

      FAQS

      • Which processor or adapter can be installed in Allen-Bradley 1746-A4?
        Use a processor or I/O adapter supported by the installed SLC 500 modular configuration; confirm its manual and power budget before fitting modules.
      • Where does the power supply mount on Allen-Bradley 1746-A4?
        The SLC 500 chassis power supply attaches at the left side. Select it for the total current demand of the installed processor and I/O modules.
      • Can Allen-Bradley 1746-A4 be part of a multiple-chassis system?
        Yes. The SLC 500 system selection guide permits up to three linked chassis when the appropriate chassis interconnect cable and system design are used.
      • How should Allen-Bradley 1746-A4 be grounded?
        Bond the chassis to the enclosure central ground bus using an individual equipment-grounding conductor, following publication 1746-IN016.
      • What should be checked before mounting Allen-Bradley 1746-A4?
        Check enclosure clearances, hole positions, mounting hardware and a flat back-panel contact. Do not distort the chassis when tightening the mounting tabs.
      • How are unused slots handled in Allen-Bradley 1746-A4?
        Use the 1746-N2 card slot filler for unused SLC 500 chassis openings to help keep debris out.
      • When should an interconnect cable be installed on Allen-Bradley 1746-A4?
        Install the specified chassis interconnect cable before attaching the power supply when the approved system layout uses more than one chassis.
      • What verifies Allen-Bradley 1746-A4 after installation?
        Check the complete catalog marking, ground bond, power-supply attachment, module seating and interconnect routing against the cabinet drawings before energizing.
