Decommissioning the Inverter

To decommission the inverter completely upon completion of its service life, proceed as described in this Section. If the inverter is defective and you have received a replacement device, observe the information on how to proceed when receiving a replacement device ( > Procedure for Receiving a Replacement Device).

CAUTION

Risk of injury when lifting the inverter, or if it is dropped

The inverter weighs 55 kg (121 lb). There is risk of injury if the inverter is lifted incorrectly or dropped while being transported or when attaching it to or removing it from the wall mounting bracket.

  1. Transport the inverter always as described below.

Procedure:

  1. DANGER

    Danger to life due to electric shock

    1. Disconnect the inverter from all voltage sources ( > Disconnecting the Inverter from Voltage Sources).
  2. Disconnect the DC cables from the terminal block for the DC connection using a screwdriver.
  3. Remove the AC cable from the inverter. Press the locking levers all the way upward and pull the conductors out of the terminal block for the AC cable.
  4. Press down the locking levers of the terminal block for the AC cable.
  5. Remove all connected grounding cables from the grounding terminal.
  6. If the multi-function relay or the SMA Power Control Module are used, remove the connection cable from the inverter.
  7. If other cables (e.g. data cables or network cables) are connected, remove them from the inverter.
  8. Remove all conduits with cables from the inverter.
  9. Close all enclosure openings.

  10. CAUTION

    Risk of burns due to hot enclosure parts

    1. Wait 30 minutes before disassembling the inverter. This will allow the enclosure to cool down and thus prevent burn injuries.
  11. Remove the inverter by lifting it vertically up and off the wall mounting bracket.

  12. Insert the lower enclosure lid from above and flip it down. Make sure that the ribbon cable of the communication assembly is not clamped and that the screws must protrude from the lower enclosure lid.

  13. Tighten all six screws with an Allen key (AF 3) in the order 1 to 6 (torque: 2.0 Nm (17.7 in-lb)). Make sure that the ribbon cable of the communication assembly is not clamped. By tightening the screws in the prescribed order, you avoid warping the enclosure lid, which would keep it from sealing correctly. Tip: If the screws fall out of the lower enclosure lid, insert the long screw into the lower middle hole and the five short screws into the other holes.
  14. Release the screws from the wall mounting bracket and take the bracket off the wall.
  15. If the inverter is to be stored or shipped, pack the inverter and the wall mounting bracket. Use the original packaging or packaging that is suitable for the weight and dimensions of the inverter and secure with tension belts if necessary.
  16. Dispose of the inverter in accordance with the locally applicable disposal regulations for electronic waste.
