12 Procedure for Receiving a Replacement Device
Under fault conditions, the inverter may need to be replaced. If this is the case, you will receive a
replacement device from SMA Solar Technology AG. If you received a replacement device,
replace the defective inverter with the replacement device as described in this section.
Procedure:
• Decommission the defective inverter.
• Commission the replacement device.
• Ship the defective inverter.
Decommissioning the Defective Inverter
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.
• Transport the inverter always as described below.
1.
DANGER
Danger to life due to electric shock
• Disconnect the inverter from all voltage sources (see Section 11, page 76).
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. Remove the cable for the additional grounding from the grounding terminal, if necessary.
5. If the multi-function relay or the SMA Power Control Module are used, remove the connection

6. If other cables (e.g. data cables or network cables) are connected, remove them from the
inverter.
7. Remove any installed interfaces from the inverter (see the manual for the communication
interface).
8. If surge arresters are present, remove the surge arresters from the defective inverter (see
9. Close all enclosure openings.
