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 transport lids.
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 as described in Section 12.1 "Dismantling the Inverter" (page 81).
2. Loosen the screws of the upper enclosure lid. For
this purpose, use an Allen key (AF 4).
3. Pull the upper enclosure lid forwards to remove it.
4. Remove the two transport lids from the replacement
device in the same manner.
5. If in place, remove the jumper cable for
deactivating the reverse current protection and
install it in the replacement device (see 6.7
"Activating and Deactivating the Reverse Current
Protection at Input Area A" (page 52)).
DANGER!
Danger to life due to electric shock.
During operation, there are high voltages in the inverter.
• Do not operate the inverter without the upper and lower enclosure lid during
operation.
Remove jumper cable
If you have deactivated the reverse current protection at input area A by means of the
jumper cable, you must remove the jumper cable before sending the inverter back to
SMA Solar Technology AG.
DANGER!
Danger to life due to high voltages in the inverter
Death due to 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.
