1. Install a separate type B residual-current circuit breaker
for the product.
2. Note the specifications on the sticker on the electronics
box.
3. Use a 3-pole power supply cable with a conductor
cross-section of 4 mm
2
and a temperature resistance of
90 °C.
4. Remove the cable jacket until there is only 30 mm left.
5. Connect the power supply cable to L1, N, PE, as
shown.
6. Use the strain relief clamp to secure the cable in place.
7. Observe the instructions on connecting a dual-tariff
supply; see (
