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
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.
• Carry and lift the inverter in an upright position
with several people without tilting it. With one
hand grasp the recessed grip, and with the
other hand support the top part of the
enclosure. This will prevent the inverter tipping
forward.
• If the inverter is to be transported and lifted
with a crane, remove the filler plugs on the top
of the inverter and screw the eye bolts into the
threads.
1.
Danger to life due to electric shock
• Disconnect the inverter from all voltage sources (see Section 2.2, page 7).
2. Remove the AC cable from the inverter. Press the locking levers all the way upward and pull
the conductors out of the connecting terminal plate for the AC cable.
3. Press down the locking levers of the connecting terminal plate for the AC cable.
4. Remove the cable for the additional grounding from the grounding terminal, if necessary.
