12 Decommissioning
12.1 Dismantling the Inverter
1. Disconnect the inverter and open it (see Section 8.2 "Disconnecting the Inverter from Voltage
Sources" (page 57)).
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.
12.2 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. Disassemble the inverter (see Section 12.1 "Dismantling the Inverter" (page 82)).
2. Undo the screws of the upper enclosure lid. Use an
Allen key (AF 4) to do this.
CAUTION!
Risk of burns due to hot enclosure parts
• Wait 30 minutes for the enclosure to cool down before disassembling.
DANGER!
Danger to life due to high voltages in the inverter
The capacitors in the inverter may be charged with very high voltages.
• Wait five minutes before opening the enclosure cover, in order to allow time for the
capacitors to discharge.
