Introduction
The amiciSmart Automatic Over/Under Voltage and Over Load Protection Device is designed to safeguard your electrical appliances from damage caused by sudden voltage and current fluctuations. This device provides comprehensive protection against over-voltage, under-voltage, and over-current conditions, ensuring the longevity and safe operation of your connected equipment.
It features an adjustable setting for various parameters and an auto-reconnect function, providing continuous protection without manual intervention. The device is suitable for single-phase 220V systems with a maximum current rating of 63A (13.8kW).
Product Features
- Multi-Protection: Provides protection against over-voltage, under-voltage, and over-current with a rapid action time of 0.1 seconds.
- Adjustable Settings: Users can customize the over-voltage protection range (230V-300V), under-voltage protection range (80V-210V), over-current protection range (1A-63A), and auto-reconnect time (1-500 seconds).
- Auto Reconnect: Automatically restores power supply within the set reconnect time after voltage or current returns to normal operating parameters.
- LED Display: Features a clear LED display for real-time monitoring of voltage and current values.
- Din-Rail Mounted: Designed for easy installation on standard DIN rails.
- Surge Protection: Capable of withstanding up to 440V. In case of extreme surges, the device is designed to self-sacrifice to protect connected appliances.

Installation Guide
1. Safety Precautions
- Always disconnect the main power supply before attempting any installation or wiring.
- Installation should be performed by a qualified electrician to ensure safety and proper functionality.
- Ensure the device is installed in a dry, well-ventilated area, away from direct sunlight and heat sources.
- Verify that the voltage and current ratings of the device match your electrical system requirements.
2. Mounting
The amiciSmart protection device is designed for standard DIN-rail mounting. Securely attach the device to a 35mm DIN rail within your electrical panel.

3. Wiring Diagram
Follow the wiring diagram carefully to connect the device to your electrical system. Ensure correct polarity for Live (L) and Neutral (N) connections.
- Connect the incoming Live (L) and Neutral (N) wires from the grid supply to the 'IN' terminals of the Voltage Protector.
- Connect the outgoing Live (L) and Neutral (N) wires from the 'OUT' terminals of the Voltage Protector to your house load or subsequent protective devices (e.g., RCBO).
- Ensure all connections are tight and secure to prevent loose contacts and overheating.
- Recommended wire sizes: 16 mm² for loads up to 63A, 10 mm² for loads up to 45A, and 6 mm² for loads up to 35A.

Operation and Settings
1. LED Display Overview
The device features a dual LED display. The upper display shows the current voltage, and the lower display shows the current amperage. Indicator lights next to the display show the status of over-voltage (>V), under-voltage (<V), and over-current (>A) conditions, along with a 'POWER' indicator.

2. Adjusting Parameters
To adjust the protection parameters, use the 'SET' button and the Up/Down arrow buttons.
- Enter Setting Mode: Press and hold the 'SET' button for approximately 3 seconds until the display starts flashing.
- Navigate Settings: Briefly press the 'SET' button to cycle through the adjustable parameters: Over-voltage (OVP), Under-voltage (UVP), Over-current (OCP), and Reconnect Time (RT).
- Adjust Values: When the desired parameter is flashing, use the Up (▲) and Down (▼) arrow buttons to increase or decrease the value.
- Save Settings: After adjusting all desired parameters, wait for approximately 5 seconds without pressing any button. The device will automatically save the settings and exit the setting mode.
Adjustable Ranges:
- Over-voltage Protection (OVP): 230V ~ 300V (Default: 270V)
- Under-voltage Protection (UVP): 80V ~ 210V (Default: 170V)
- Over-current Protection (OCP): 1A ~ 63A (Default: 63A)
- Auto Reconnect Time (RT): 1 ~ 500 seconds (Default: 30 seconds)

Troubleshooting
- Device Not Powering On: Check the incoming power supply. Ensure Live and Neutral wires are correctly connected and secure.
- Frequent Tripping: Review your set over-voltage, under-voltage, and over-current parameters. They might be set too sensitively for your electrical environment. Adjust the ranges slightly to accommodate minor fluctuations.
- No Auto Reconnect: Verify the reconnect time setting. If the fault condition persists, the device will not reconnect until the electrical parameters stabilize.
- Display Not Working: Ensure the device is receiving power. If power is present and the display is off, contact customer support.
- Device Destroyed After Surge: This is an intended safety feature. The device is designed to sacrifice itself to protect your appliances from severe surges (above 440V). Replace the device if this occurs.
Maintenance
- Keep the device clean and free from dust. Use a dry cloth for cleaning.
- Do not expose the device to water or excessive moisture.
- Periodically check wiring connections to ensure they remain tight and secure.
- Avoid placing the device near strong electromagnetic fields.
