Commissioning the Inverter


Qualified person

Requirements:

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

  • The product must be correctly mounted.

  • All cables must be correctly connected.

Procedure:

  1. If the DC load-break switch has been protected against restarting with a padlock, open and detach the padlock on the DC load-break switch.
  2. 3195129740
  3. Turn the DC load-break switch of the inverter to position I.
  4. Switch on the AC circuit breaker.
  5. All 3 LEDs light up. The start-up phase begins.
  6. During start-up phase of the inverter, the desired firmware is being installed.
  7. All 3 LEDs go out again after approximately 90 seconds.
  8. The green LED starts to flash and, if the inverter is connected via Speedwire, the blue LED also starts to flash.
  9. 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.
  10. 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.
  11. If the red LED lights up, an event has occurred. Find out which event has occurred and, if necessary, initiate countermeasures.
