Proper wiring of high-power rectifier power supplies is crucial for ensuring safe and efficient operation. This guide provides detailed step-by-step instructions for wiring high-power rectifiers, along with key safety considerations to prevent accidents and equipment damage.
Always disconnect the main power supply before starting any wiring work. Confirm that the rectifier is completely de-energized to avoid electric shock hazards.
Power Supply Wiring Steps
1. Remove Metal Cover Plate
Remove the metal cover plate located at the rectifier power switch position. Operate carefully to avoid knocking against the switch and surrounding wiring terminals.
2. Thread the Power Cable
At the cable interface above the rectifier power switch, thread in the power cable to be connected, which is protected by a corrugated tube. The corrugated tube must cover the exposed parts of the power cable to provide insulation and prevent wear.
3. Adjust Power Cable Length
After threading the power cable into the rectifier interior, pull it out from the power switch position so that the end of the power cable is flush with the switch wiring port. Avoid excessive length that may cause messy internal wiring or insufficient length that creates tension on connections.
4. Secure Power Cable Connections
Connect the phase wire and neutral wire of the power cable to the corresponding terminals of the power switch in sequence. Tighten the terminal screws firmly to ensure secure connections without looseness, preventing heating or faults caused by poor contact.
5. Replace Metal Cover Plate
Reinstall the removed metal cover plate and tighten the cover plate fixing screws. Ensure the cover plate fits tightly against the rectifier body without looseness to provide protection.
6. Connect Grounding Wire
Finally, connect the grounding wire that meets specifications to the dedicated grounding terminal of the rectifier. Tighten the terminal screw to ensure electrical safety during equipment operation.

Key Safety Considerations
Critical Safety Precautions
- Power Disconnection: Always disconnect the main power supply before starting wiring work. Confirm that the rectifier is completely de-energized to avoid electric shock hazards.
- Cable Specifications: Power cable specifications must match the rectifier's rated power. Never use cables with insufficient wire gauge.
- Proper Grounding: The grounding terminal must be reliably grounded. Do not connect the ground wire to neutral or phase terminals to prevent electric leakage accidents.
- Final Inspection: After completing the wiring, check that internal wiring is neat without pinched or worn wires before powering on for trial operation.
