1. Ensure all power is OFF at the main supply before beginning wiring.
2. Connect the incoming live (L) and neutral (N) wires to the top terminals as indicated by the wiring diagram.
3. Connect the outgoing live (L) and neutral (N) wires to the bottom terminals.
4. Tighten all terminal screws securely to prevent loose connections, which can cause overheating.
5. Double-check all connections for correctness and tightness before restoring power.

6. Operating Instructions

6.1 Switching ON/OFF

• To switch the circuit breaker ON, push the handle upwards to the 'I' (ON) position.
• To switch the circuit breaker OFF, push the handle downwards to the 'O' (OFF) position.

6.2 Monthly Test

To ensure the residual current protection function is operating correctly, a monthly test must be performed:

1. Ensure the circuit breaker is in the ON position.
2. Press the 'Test' button (T) located on the front of the device.
3. The circuit breaker should immediately trip to the OFF position. This indicates the RCD function is working.
4. To reset, push the handle fully down to the OFF position, then push it back up to the ON position.
5. If the circuit breaker does not trip when the test button is pressed, it may be faulty and should be replaced immediately by a qualified electrician.

7. Maintenance

The ETEK Residual Automatic Circuit Breaker is designed for minimal maintenance. However, regular checks are important for continued safe operation.

• Monthly Test: As described in Section 6.2, perform the RCD test monthly.
• Visual Inspection: Periodically inspect the circuit breaker for any signs of physical damage, discoloration, or loose connections.
• Cleaning: If necessary, gently wipe the exterior of the circuit breaker with a dry, soft cloth. Do not use abrasive cleaners or solvents. Ensure power is disconnected before cleaning.

Do not attempt to open or repair the circuit breaker. Refer all repairs to qualified service personnel.
