Decommissioning the Inverter

Qualified person

CAUTION

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

The inverter weighs 61 kg. 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. Carry and lift the inverter in an upright position with several people without tilting it. With one hand grasp the recessed grip, and with the other hand support the top part of the enclosure. This will prevent the inverter tipping forward.

  2. If the inverter is to be transported and lifted with a crane, remove the filler plugs on the top of the inverter and screw the eye bolts into the threads.

Procedure:

  1. DANGER

    Danger to life due to high voltages

    1. Disconnect the inverter from all voltage sources ( > Disconnecting the Inverter from Voltage Sources).
  2. 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.
  3. Press down the locking levers of the terminal block for the AC cable.
  4. If the multi-function relay or the SMA Power Control Module are used, remove the connection cable from the inverter.
  5. If other cables (e.g. data cables or network cables) are connected, remove them from the inverter.

  7. Tighten all six screws with an Allen key (AF 3) in the order 1 to 6 (torque: 2.0 Nm ± 0.3 Nm). By tightening the screws in the prescribed order, you avoid warping the 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.

  8. CAUTION

    Risk of burns due to hot enclosure parts

    1. Wait 30 minutes for the enclosure to cool down.
  9. If the inverter is disassembled due to a device replacement, keep the DC load-break switch in a safe place until the new inverter is installed. The new inverter will be delivered without a DC load-break switch and the present DC load-break switch will be required for installation.
  10. If the inverter is protected from being lifted off, unscrew the screws out of the lower drill holes in the rear panel of the inverter.
  11. Remove the inverter by lifting it up and off the wall mounting bracket.
  12. If the inverter is to be stored or shipped in packaging, pack the inverter, the wall mounting bracket and, if applicable, the DC load-break switch. Use the original packaging or packaging that is suitable for the weight and dimensions of the inverter.
  13. Dispose of the inverter in accordance with the locally applicable disposal regulations for electronic waste.
