5. Instal·lació
The SVP-63A is designed for DIN rail mounting. Follow the wiring diagram below for proper installation.
- Mount the device onto a standard 35mm DIN rail in your electrical distribution box.
- Ensure the main power supply is OFF before proceeding with wiring.
- Connect the incoming Live (L) and Neutral (N) wires to the 'IN' terminals at the top of the protector.
- Connect the outgoing Live (L) and Neutral (N) wires to the 'OUT' terminals at the bottom of the protector, leading to your protected load.
- Comproveu dues vegades que totes les connexions estiguin ben ajustades i que la polaritat sigui correcta.

6. Configuració i configuració
The SVP-63A allows for adjustment of various protection parameters. Use the 'SET' button and the up/down arrow buttons to navigate and modify settings.
- Accés a la configuració: Press and hold the 'SET' button for a few seconds until the display starts flashing, indicating entry into the setting mode.
- Ajust del sobrevoltage Value (>V): Use the up/down arrows to set the desired overvoltage threshold. Default is 270V, adjustable from 230V to 300V.
- Ajust del subvolumtage Value (<V): Use the up/down arrows to set the desired undervoltage threshold. Default is 170V, adjustable from 145V to 210V.
- Adjusting Overcurrent Value (>A): Use the up/down arrows to set the desired overcurrent threshold. Default is 63A, adjustable from 1A to 63A.
- Adjusting Fault Recovery Delay Time: Set the delay time before the device automatically restores power after a fault condition has cleared.
- Desar la configuració: After making adjustments, press the 'SET' button again to cycle through the settings and save them. The display will stop flashing.

7. Instruccions de funcionament
Once installed and configured, the SVP-63A operates automatically to protect your electrical system.
- Encès: After successful installation and wiring, switch on the main power supply. The device's LED display will illuminate, showing the current voltage i lectures actuals.
- Seguiment: The top LED display shows the voltage (V), and the bottom LED display shows the current (A).
- Protection Indication: Indicator lights on the front panel will illuminate to show active protection states: '>V' for overvoltage, '<V' for undervoltage, and '>A' for overcurrent.
- Automatic Disconnection: If any set parameter (overvoltage, minvartage, overcurrent) is exceeded, the device will automatically cut off the power supply to protect connected equipment.
- Fault Recovery: After a fault condition clears, the device will wait for the set recovery delay time before automatically restoring power.
8. Manteniment
The Walfront SVP-63A requires minimal maintenance to ensure optimal performance.
- Inspecció periòdica: Periodically check the device for any visible damage, loose connections, or signs of overheating.
- Neteja: Keep the device clean and free from dust. Use a dry, soft cloth for cleaning. Do not use liquid cleaners or solvents.
