Qualified person

Requirements:

  • A means of disconnecting the inverter from the PV modules must be present.

  • The AC circuit breaker must be correctly rated and mounted.

  • The inverter must be correctly mounted.

  • All cables must be correctly connected.

  1. Position the enclosure lid. The two guide pins on the enclosure lid must slide into the guide openings on the enclosure lid.
    2. 10727604748
  2. Ensure that the cover sits straight on the enclosure.
    3. 10345893260
  3. Hold the enclosure lid pressed against the enclosure and screw it tight. (Hex socket, AF 8, torque: 18 Nm).

  4. Place the cover on the screw in the enclosure lid.
  5. Option: Switch on the transformer.
  6. Switch on DC via the PV combiner box or the external DC switch.
  7. Switch on the AC circuit breaker.
  8. All 3 LEDs light up. The start-up phase begins.
  9. All 3 LEDs go out again after approximately 90 seconds.
  10. Depending on the available power, the green LED pulses or is continuously illuminated. The inverter is feeding in.
  11. If the green LED is still flashing, the conditions for activating feed-in operation are not yet met. As soon as the conditions for feed-in operation are met, the inverter starts with feed-in operation and, depending on the available power, the green LED will light up continuously or it will pulse.
  12. If the red LED lights up, an event has occurred. Find out which event has occurred and, if necessary, initiate countermeasures.
