Qualified person

To decommission the inverter completely upon completion of its service life, proceed as described in this Section.

CAUTION

Risk of injury due to weight of product

Injuries may result if the product is lifted incorrectly or dropped while being transported or mounted.

  1. Transport and lift the product carefully. Take the weight of the product into account.
  2. Wear suitable personal protective equipment for all work on the product.

Procedure:

  1. Disconnect the inverter from all voltage sources ( > Disconnecting the Inverter from Voltage Sources).

  2. CAUTION

    Risk of burns due to hot enclosure parts

    1. Wait 30 minutes for the enclosure to cool down.
  3. Remove optional accessories (e.g., SMA Backup Start, Wi-Fi antenna).
  4. Undo the screw for the additional grounding (TX25) and remove the grounding cable.
  5. Unplug the 2-pole connector for the external rapid shutdown initiator from the adapter.
  6. Unplug the 2-pole connector to which the DC load-break switch is connected from the adapter.
  7. Unplug the adapter from the GSI slot.
  8. Plug the 2-pole connector to which the DC load-break switch is connected into the GSI slot.
  9. Remove the battery power cable from the terminals.
  10. Remove the cable for grounding the PV modules. To do this, twist off the cable from the busbar for grounding the DC connection (PZ 2).
  11. Unplug the network cable from the BATTERY network port.
  12. Remove the network cable from the LAN-1 and LAN-2 network ports.
  13. Unplug the connector from the SPS slot.
  14. Remove the protective conductors of the AC cables from the busbar. To do this, first undo the screw (PZ2).
  15. Remove the N and L conductors from the SPS terminals.
  16. Remove N, L1, and L2 from the AC terminals.
  17. Remove the ferrite. To do this, cut the cable tie.
  18. Detach all conduits and remove all cables from the inverter.
