2 SLC 500™ Power Supplies Important User Information Because of the variety of uses for the products described in this publication, those responsible for the application and use of this control equipment must satisfy themselves that all necessary steps have been taken to assure that each application and use meets all performance and safety requirements, including any applicable laws, regulations, codes and standards.
English Section SLC 500™ Power Supplies (Catalog Numbers 1746-P1, 1746-P2, 1746-P3, 1746-P4, 1746-P5, 1746-P6, and 1746-P7) Overview Install your power supply using these installation instructions. The only tools you require are Flat head (1/8”) and Phillips head (1/4”, #2) screwdrivers. ! ATTENTION: Electrostatic discharge can damage integrated circuits or semiconductors if you touch backplane connector pins. Follow these guidelines when you handle the power supplies.
4 SLC 500™ Power Supplies Hazardous Location Considerations This equipment is suitable for use in Class I, Division 2, Groups A, B, C, D or non-hazardous locations only. The following WARNING statement applies to use in hazardous locations. WARNING: EXPLOSION HAZARD • Substitution of components may impair suitability for Class I, Division 2. • Do not replace components or disconnect equipment unless power has been switched off or the area is known to be nonhazardous.
SLC 500™ Power Supplies 5 Install the Chassis Interconnect Cable (Optional) To connect up to three SLC 500™ chassis together, install the chassis interconnect cable before installing the power supply . SLC 500 chassis/A For more information, see the SLC 500 Modular Style Installation and Operation Manual (publication 1747-6.2). Power Supply Installation 1. Align the circuit board of the power supply with the card guides on the left side of the chassis . 2.
6 SLC 500™ Power Supplies Power Supply Wiring 1. Place the input voltage jumper to match the input voltage. (This does not apply to the 1746-P3, -P5, -P6, and -P7 power supplies, which do not have a jumper.) ! ATTENTION: Set the input jumper before applying power. Hazardous voltage is present on exposed pins when power is applied; contact with the pin may cause injury to personnel.
SLC 500™ Power Supplies 7 3. Connect incoming power. ATTENTION: Turn off incoming power before connecting wires; failure to do so could cause injury to personnel and/or equipment.
8 SLC 500™ Power Supplies 1746-P3 Wiring Considerations The information below describes special wiring considerations for the 1746-P3. ! ATTENTION: Any voltage applied to the 1746-P3 DC NEUT terminal will be present at the SLC logic ground and the processor DH-485 port.
SLC 500™ Power Supplies 1746-P3 Processor 9 SLC 500 Chassis Door Not Used DH±485 Port Not Used SLC Logic Resistor • Chassis • +24V dc DC Neut Chassis Ground Earth Ground 4. (Optional) For the 1746-P1, -P2,-P4, -P5 and -P6 power supplies, use PWR OUT +24V dc and PWR OUT COM terminals to power 24V dc sensors and loads. The terminals on the 1746-P1, 1746-P2, 1746-P5 and 1746-P6 provide an isolated, nonfused 200 mA, 24V dc power supply.

SLC 500™ Power Supplies 11 Power Supply Undervoltage Operation SLC 500 controllers continue to operate (hold-up) for a short period of time if the input voltage to the power supply drops below the recommended operating voltage range. The controller continues to scan the user program and control I/O during this time. CPU hold-up for each power supply is shown on pages 9 and 10.
