5.1. Wiring Diagram

Connect the device according to the following steps:

1. Disconnect Power: Turn off the main circuit breaker to ensure no power is supplied to the installation area.
2. Mount Device: Clip the AVP-63 onto the DIN rail in your electrical panel.
3. Input Wiring: Connect the incoming Live (L) wire to the 'L' terminal marked 'IN' and the incoming Neutral (N) wire to the 'N' terminal marked 'IN'.
4. Output Wiring: Connect the outgoing Live (L) wire to the 'L' terminal marked 'OUT' and the outgoing Neutral (N) wire to the 'N' terminal marked 'OUT'. These wires will lead to the protected electrical load.
5. Secure Connections: Ensure all wire connections are tight and secure to prevent loose contacts and overheating.
6. Restore Power: Once all connections are verified, restore power to the main circuit breaker. The device will power on and display current voltage and current readings.

Note: For optimal performance and safety, use appropriate wire gauges for your electrical load.

6. Operating Instructions

The AVP-63 provides real-time monitoring and allows for custom adjustment of protection parameters.

6.1. Real-time Monitoring

Upon power-up, the top LED display will show the current line voltage (V) and the bottom LED display will show the current load current (A).

6.2. Parameter Setting

To adjust the protection parameters (over-voltage, under-voltage, over-current, and recovery delay time):

Figure 6.1: Flowchart for adjusting protection parameters on the AVP-63.

1. Enter Setting Mode: Press and hold the SET button for approximately 3-5 seconds until the display starts flashing, indicating entry into setting mode.
2. Navigate Parameters: Briefly press the SET button to cycle through the adjustable parameters: Over-Voltage (OV), Under-Voltage (UV), Over-Current (OC), and Fault Recovery Delay Time (dEL).
3. Adjust Value: When the desired parameter is displayed and flashing, use the Up and Down buttons to increase or decrease the value.
4. Confirm Setting: After setting the value, briefly press the SET button again to confirm the value and move to the next parameter, or wait for 5-10 seconds for the device to automatically save the setting and exit setting mode.
5. Exit Setting Mode: Once all parameters are set, the device will automatically exit setting mode after a period of inactivity, or you can press and hold the SET button again to exit.

6.3. Manual ON/OFF Control

The device can be manually switched on or off using the ON/OFF button. A brief press will toggle the output state. This function is independent of the protection settings.

7. Maintenance

The AVP-63 is designed for minimal maintenance. Follow these guidelines to ensure its longevity and proper function:

• Regular Inspection: Periodically inspect the device and its wiring for any signs of damage, loose connections, or discoloration.
• Cleaning: If necessary, gently wipe the device with a dry, soft cloth. Do not use abrasive cleaners or solvents.
• Environmental Conditions: Ensure the operating environment remains within the specified temperature and humidity ranges to prevent premature failure.
• No User Serviceable Parts: Do not attempt to open the casing or repair the device yourself. Refer all servicing to qualified personnel.
