12 Decommissioning the Inverter
To decommission the inverter completely upon completion of its service life, proceed as described
in this Section. If the inverter is defective and you have received a replacement device, observe the
information on how to proceed when receiving a replacement device (see Section 13 "Procedure
for Receiving a Replacement Device", page 67).
Risk of injury when lifting the inverter, or if it is dropped
The inverter weighs 55 kg (121 lb). 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.
Procedure:
1.
Danger to life due to electric shock
• Disconnect the inverter from all voltage sources (see Section 9, page 43).
2. Disconnect the DC cables from the connecting terminal plate for the DC connection using a
screwdriver.
3. 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.
4. Press down the locking levers of the connecting terminal plate for the AC cable.
5. Remove all connected grounding cables from the grounding terminal.
6. If the multi-function relay or the SMA Power Control Module are used, remove the connection
cable from the inverter.
