Setup and Installation
Proper installation is critical for the safe and effective operation of your leakage protector. Ensure all steps are followed carefully by a qualified professional.
DIN Rail Mounting
The amiciSmart 3-Phase Leakage Protector is designed for easy installation on a standard DIN rail. Securely clip the device onto the DIN rail within your electrical distribution board. Ensure it is firmly seated to prevent movement.
Wiring Diagram
Refer to the wiring diagram below for correct connection of the input power (L1, L2, L3, N) and the output load (L1, L2, L3, N). Ensure all connections are tight and correctly phased. Incorrect wiring can lead to malfunction or hazardous conditions.

Operating Instructions
Once installed, the device operates automatically to protect against electrical faults. However, regular testing and understanding its features are important.
Residual Current Test Button
The device is equipped with a 'Test Monthly' button (typically yellow). Press this button once each month to verify that the leakage protection function is operating correctly. When pressed, the device should trip, indicating the leakage protection mechanism is functional. Reset the device after testing.

Switchable Leakage Protection
This device features a switchable leakage protection function. This allows you to temporarily disable the leakage protection if necessary, for example, in environments where a 30mA leakage circuit breaker might frequently trip due to specific conditions. However, it is not recommended to operate the device with leakage protection disabled for extended periods, especially in applications requiring human safety. Always re-enable leakage protection for normal operation.

Maintenance
The amiciSmart Leakage Protector requires minimal maintenance. The primary maintenance task is the monthly testing of the residual current device (RCD) function using the 'Test Monthly' button, as described in the Operating Instructions section. Regularly inspect the device for any signs of physical damage, overheating, or loose connections. Any issues should be addressed by a qualified electrician immediately.
Troubleshooting
If you encounter issues with your amiciSmart Leakage Protector, refer to the following common troubleshooting steps:
- Device Trips Constantly: If the device trips frequently after installation, this indicates a persistent leakage fault in your electrical system. This issue needs to be investigated and resolved by a qualified electrician. Do not bypass the protection or ignore constant tripping.
- Leakage Protection Not Working (Test Button Fails): If pressing the 'Test Monthly' button does not trip the device, the leakage protection mechanism may be faulty. Disconnect power and contact a qualified electrician for inspection and replacement.
- Device Does Not Reset: If the device trips and cannot be reset, there may still be an active fault (overcurrent, short-circuit, or leakage) or internal damage. Ensure the fault is cleared before attempting to reset. If it still fails to reset, consult an electrician.
- No Power Output: Check the input power supply and ensure the device is in the 'ON' position. If the device is not tripped and there's still no output, inspect wiring connections or consult an electrician.
