13 Decommissioning
13.1 Dismantling the Inverter
1. Disconnect the inverter from voltage sources and open it (see Section9.2 "Disconnecting the
Inverter from Voltage Sources", page64).
2. Remove all communication cables from the inverter.
3. If necessary, remove the padlock.
4. Remove the inverter by lifting it upwards off the wall mounting bracket.
13.2 Replacing the Enclosure Lid
In the event of a fault, your inverter may need to be replaced. If this is the case, you will receive a
replacement device fitted with an upper and lower transport lid.
Prior to returning your inverter to SMA Solar Technology AG, you must replace the upper and lower
enclosure lids of your inverter with the corresponding transport lids:
1. Dismantle the inverter (see Section13.1 "Dismantling the Inverter", page90).
2. Undo the screws of the upper enclosure lid. Use an
Allen key (AF 4) to do this.
Risk of burns due to hot enclosure parts
• Wait 30 minutes for the enclosure to cool down before disassembling.
Danger to life due to high voltages in the inverter
The capacitors in the inverter may be charged with very high voltages.
• Wait 5 minutes before opening the enclosure cover, in order to allow time for the capacitors
to discharge.
