Switching the Inverter On

Requirements:

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

  • The product must be correctly mounted.

  • All cables for the AC connection, DC connection, and communication must be correctly connected.

  • Unused enclosure openings must be sealed tightly with sealing plugs.

Procedure:

  1. Make sure that the AC cable compartment is closed.
  2. Switch on the two DC load-break switches.
  3. Switch the AC voltage supply on.
  4. If the green and red LEDs flash simultaneously during initial commissioning, operation is stopped because no country data set has been set yet. For the inverter to begin operation, the configuration must be completed and a country data set must be set.
  5. 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.
  6. If the red LED lights up, an event has occurred. Find out which event has occurred and, if necessary, initiate countermeasures.
  7. Ensure that the inverter feeds in correctly.
