1. 1

   Ensure external operating voltage (1x230V+N+PE) is connected to AA1:X11.

2. 2

   If using a separate earth-fault breaker, disconnect the blue cable from X7:24 and connect it to the enclosed top clamp with the operating zero.

3. 3

   Connect a blue cable (min 0.75 mm²) between the top clamp and X11:N on AA1.

4. 4

   Refer to the illustration for correct terminal connections (AA1:X2 to AA1:X9 if applicable).
