Setup and Installation
The A9FDD225 is designed for DIN rail mounting. Ensure the electrical panel is de-energized before proceeding.
- Power Disconnection: Turn off the main power supply to the electrical panel where the AFDD will be installed. Verify with a voltage tester that no power is present.
- Mounting: Clip the AFDD onto the DIN rail in the designated slot within the electrical panel. Ensure it is securely fastened.
- Wiring:
- Connect the incoming phase (L) wire to the top terminal marked 'L'.
- Connect the incoming neutral (N) wire to the top terminal marked 'N'.
- Connect the outgoing phase (L) wire to the bottom terminal marked 'L'.
- Connect the outgoing neutral (N) wire to the bottom terminal marked 'N'.
- Ensure all connections are tight and secure to prevent loose contacts and overheating.
- Verification: Double-check all wiring connections against the wiring diagram (if available in your panel documentation) and ensure no bare wires are exposed.
- Power Restoration: Once installation is complete and verified, restore power to the electrical panel.
Operating Instructions
Turning On/Off:
- To Turn On: Push the toggle switch upwards to the 'ON' position. The indicator window should show green (or similar indication of normal operation).
- To Turn Off: Push the toggle switch downwards to the 'OFF' position.
Test Function:
The AFDD is equipped with a test button to verify its arc fault detection functionality. It is recommended to perform this test monthly.
- Ensure the AFDD is in the 'ON' position and power is supplied.
- Press and hold the 'TEST' button. The AFDD should trip, moving the toggle switch to the 'OFF' position.
- Release the 'TEST' button.
- To restore power, reset the AFDD by pushing the toggle switch fully down to 'OFF' and then back up to 'ON'.
- If the AFDD does not trip during the test, it may be faulty and should be replaced by a qualified electrician.
Maintenance
The Schneider Electric A9FDD225 AFDD is designed for maintenance-free operation under normal conditions. However, periodic checks are recommended:
- Monthly Test: Perform the test function as described in the "Operating Instructions" section to ensure the arc fault detection mechanism is working correctly.
- Visual Inspection: Periodically inspect the device for any signs of physical damage, discoloration, or loose connections. Any issues should be addressed by a qualified electrician.
- Cleaning: If necessary, gently wipe the exterior of the device with a dry, soft cloth. Do not use abrasive cleaners or solvents. Ensure power is off before cleaning.
