Installation Instructions ATTENTION ! Environment and Enclosure This equipment is intended for use in a Pollution Degree 2 industrial environment, in overvoltage Category II applications (as defined in IEC publication 60664-1), at altitudes up to 2000 m (6561 ft) without derating. This equipment is considered Group 1, Class A industrial equipment according to IEC/CISPR Publication 11.
Installation Instructions 5 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 ! IMPORTANT Electrostatic discharge can damage integrated circuits or semiconductors if you touch backplane connector pins. Follow these guidelines when you handle the power supplies. • • • • • Touch a grounded object to discharge static potential.
Installation Instructions Environnements dangereux Les produits marqués « CL 1, DIV 2, GP A, B, C, D » ne conviennent qu’à une utilisation en environnements de Classe I, Division 2, Groupes A, B, C, D dangereux et non dangereux. Chaque produit est livré avec des marquages sur sa plaque d’identification qui indiquent le code de température pour les environnements dangereux.
Installation Instructions 7 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 Hardware Style User Manual, publication 1747-UM011. Power Supply Installation 1. Align the circuit board of the power supply with the card guides on the left side of the chassis. 2.
Installation Instructions Power Supply Wiring For more information on wiring, see Allen-Bradley Programmable Controller Grounding and Wiring Guidelines, publication 1770-4.1. TIP Refer to publication 1746-IN016, for chassis installation and grounding requirements. 1. Place the input voltage jumper to match the input voltage. (This does not apply to the 1746-P3, 1746-P5, 1746-P6, and 1746-P7 power supplies, which do not have a jumper.
Installation Instructions 9 2. Connect the ground screw of the power supply to the nearest ground or ground bus. Use a 1.68 mm (#14 AWG) 75° Copper wire (Category 1 per Industrial Automation Wiring and Grounding Guidelines, publication 1770-4.1) and keep the leads as short as possible. The 1746-P4 is shown below. Chassis Ground Tighten terminal screws to 0.8 Nm (7 lb-in). Nearest Ground Bus 3. Refer to page 11 for special wiring considerations for the 1746-P3. 4. Connect incoming power.

Installation Instructions 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 14 and 16.
