13 Decommissioning
13.1 Dismantling the Inverter
1. Disconnect the inverter (see Section 9 "Disconnecting the Inverter from Voltage Sources",
page 61).
2. Remove any connected communication cables from the inverter.
3. Screw off all projecting cable glands.
4. If necessary, open the anti-theft lock.
5. Lift the inverter off the rear panel and unscrew and remove rear panel as necessary.
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 transport lids.
Prior to returning your inverter to SMA Solar Technology AG, you will need to replace the upper and
lower enclosure lids with the corresponding transport lids.
Risk of burns due to hot enclosure parts
• Wait 30 minutes for the enclosure to cool down before disassembling.
Danger to life due to electric shock
During operation, there are high voltages present in the inverter.
• Do not operate the inverter without the upper and lower enclosure lid in place.
Dismantling Surge Arresters Type II
If you have retrofitted your inverters with surge arresters Type II, they must be dismantled before
returning the inverter to SMA Solar Technology AG (see Section 12.4 "Replacing Surge
Arresters Type II", page 88).
Danger to life due to high voltages in the inverter
Death from electric shock
After disconnecting the inverter, there is residual voltage in the inverter. The inverter takes 20 minutes
to discharge.
• Wait 20 minutes before you open the upper enclosure lid or the DC lid.
