3. Safety Information
WARNING: Improper installation or use can lead to electric shock, fire, or other hazards. Always follow these safety guidelines:
- Ensure the power supply is disconnected from the main power source before any installation or maintenance.
- Installation should be performed by a qualified electrician in accordance with all local and national electrical codes.
- Do not operate the power supply beyond its specified voltage and current ratings.
- Ensure proper ventilation to prevent overheating.
- Do not expose the unit to moisture or extreme temperatures.
- Verify correct polarity when connecting input and output wires.
4. Setup and Installation
Follow these steps for proper installation of the PLD-60-700B LED Power Supply:
- Mounting: Securely mount the power supply in a location that allows for adequate air circulation and is suitable for indoor use (IP42 rated).
- Input Wiring: Connect the AC input wires to the designated terminals. The PLD-60-700B requires 230VAC input only. Refer to the mechanical specification diagram for wire identification (AC/N (BLUE) and AC/L (BROWN)).
- Output Wiring: Connect the DC output wires to your LED load. Ensure correct polarity: V+ (RED) to the positive terminal of the LED load and V- (BLACK) to the negative terminal.
- Verification: Double-check all connections for secure fit and correct polarity before applying power.

6. Maintenance
The PLD-60-700B LED Power Supply is designed for reliable operation with minimal maintenance. However, periodic checks can help ensure longevity:
- Cleaning: Ensure the unit is free from dust and debris, especially around ventilation areas, to maintain proper heat dissipation. Disconnect power before cleaning.
- Connections: Periodically inspect all wiring connections to ensure they remain secure and free from corrosion.
- Environmental Conditions: Verify that the operating environment remains within the specified temperature and humidity ranges.
7. Troubleshooting
If the LED Power Supply is not functioning as expected, consider the following common issues:
| Problem | Possible Cause | Solution |
|---|---|---|
| No output from power supply. | No AC input power; Incorrect wiring; Overload/Short circuit protection activated; Over temperature protection activated. | Check AC power source and connections; Verify input/output wiring polarity; Reduce load or check for short circuits; Allow unit to cool down. |
| LEDs flickering or dim. | Unstable input voltage; Load exceeding power supply capacity; Loose connections. | Ensure stable AC input; Verify LED load is within specifications; Check all wiring connections. |
If issues persist after troubleshooting, contact customer support.
