GETTING STARTED GUIDE48 VDC Industrial Power Supply With screw terminals and DIN clipThe 48 VDC Industrial Power Supply with screw terminals and DIN clip is an accessory that supplies power to National Instruments hardware. This document contains instructions for wiring the terminals and operating the power supply, and specifications for the power supply.UnpackingCarefully inspect the shipping container and the power supply for damage. Check for visible damage to the metal work. If damage appears to have occurred during shipment, file a claim with the carrier. Retain the packing material for possible inspection and/or reshipment. Output TerminalsThe 48 VDC Industrial Power Supply has a total of four output terminals, providing two positive (+) output terminals and two negative (-) output terminals. Both positive terminals are wired together internally, and both negative terminals are wired together internally. Refer to the Specifications section in this guide for information on the output voltage and current, as well as the operating temperature of the power supply.Wiring the TerminalsThis section describes wiring for the 48 VDC Industrial Power Supply. Table 1 provides a list of basic requirements for wiring.Hazardous Voltage To avoid risk of electric shock, this product must be mounted in a metal enclosure by qualified personnel.Table 1. Wiring RequirementsType Screw TerminalsSolid or stranded wire 0.5 to 1.5 mm2American wire gauge 30 to 16 AWGFerrules Allowed, but not requiredWire stripping length 6 to 7 mm (0.25 in.)2 | ni.com | 48 VDC Industrial Power Supply Getting Started GuideConsider the following when wiring the 48 VDC Industrial Power Supply: Use appropriate copper cables designed to operate up to 105 C. Follow national installation codes and installation regulations. Up to two stranded wires with the same cross section are permitted in one connection point.Complete the following steps to connect wires to the input and output terminals.1. Disconnect all power before wiring and installation.2. Strip the ends of the wires according to the requirements in Table 1.3. Turn the screw counterclockwise until the terminal is open.4. Insert the exposed portion of the wire completely inside the terminal. If you use stranded wire, ensure all strands enter the terminal.5. Turn the screw clockwise until the wire is secure in the terminal.6. Repeat steps 2 to 5 for each of the other terminals.7. Ensure all wires are properly seated and not loose.8. Ensure all other equipment can be powered on without a hazard.9. If the enclosure is secured, apply mains voltage to the 48 VDC Industrial Power Supply.Operating the 48 VDC Industrial Power SupplyTurn the power off before working on the power supply. Protect against inadvertent re-powering.Follow all local and national codes to make sure the wiring is correct.Use caution to prevent any foreign objects from entering the metal enclosure.Do not use in wet locations or in areas where moisture or condensation are expected.Do not open, modify, or repair the unit.Service PartsThe 48 VDC Industrial Power Supply does not contain any serviceable parts. If damage or malfunction occurs during operation, immediately turn the power off and discontinue use.Note Attempting to repair or modify the 48 VDC Industrial Power Supply voids the warranty.48 VDC Industrial Power Supply Getting Started Guide | National Instruments | 3SpecificationsNote Specifications are subject to change without notice.This power supply is designed for installation in an enclosure and is intended for general use, such as in industrial control and instrumentation equipment.
