4. Setup and Installation

Follow these steps to safely install your power supply:

1. Mounting: Securely mount the power supply in a well-ventilated area using appropriate screws. Ensure there is adequate space around the unit for airflow.
2. Input Voltage Selection: Locate the red switch on the side of the unit. Set it to either 110V or 220V according to your local mains voltage. WARNING: Verify this setting before connecting to power.
3. AC Input Wiring: Connect your AC mains power to the input terminals. Refer to Figure 3.3 for terminal identification:
   • Connect the Live (L) wire to the 'L' terminal.
   • Connect the Neutral (N) wire to the 'N' terminal.
   • Connect the Ground (GND) wire to the '⊗' (ground) terminal.
   Ensure all wires are stripped to the correct length and securely fastened in their respective terminals.
4. DC Output Wiring: Connect your 12V DC load to the output terminals. Refer to Figure 3.3 for terminal identification:
   • Connect the positive (+) wire of your load to the '+V' terminals.
   • Connect the negative (-) wire of your load to the '-V' terminals.
   Multiple '+V' and '-V' terminals are provided for convenience and to distribute current. Ensure the total current drawn by your load does not exceed 30A.
5. Final Check: Double-check all connections for correctness and security. Ensure no bare wires are exposed.

5. Operation

After completing the setup and safety checks:

1. Apply AC power to the unit. The power supply should turn on, and the internal fan (if present) may start.
2. Verify that your connected 12V DC load is receiving power and operating as expected.
3. The output voltage can be finely adjusted using the small potentiometer (V ADJ) located near the output terminals. Use a small screwdriver to turn it clockwise to increase voltage or counter-clockwise to decrease it within a small range.

6. Maintenance

The PPOZYLPC S-360-12 is designed for minimal maintenance. However, periodic checks can ensure optimal performance and longevity:

• Cleaning: Periodically clean the exterior of the unit with a dry, soft cloth. Ensure ventilation openings are free from dust and debris. Do not use liquid cleaners.
• Ventilation: Ensure the installation area remains well-ventilated and free from obstructions.
• Connections: Occasionally check all wiring connections to ensure they remain tight and secure. Loose connections can cause overheating or intermittent operation.
• Environmental Conditions: Avoid operating the unit in environments with excessive dust, moisture, or extreme temperatures.
