Decommissioning the Inverter
Risk of injury when lifting the inverter, or if it is dropped
The inverter weighs 30 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.
• Transport and lift the inverter carefully.
Procedure:
1.
Danger to life due to high voltages
• 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. If the multi-function relay or the SMA Power Control Module are used, remove the connection
cable from the inverter.
5. If other cables (e.g. data cables or network cables) are connected, remove them from the
inverter.
6. Insert the lower enclosure lid from above and
fold it down. The screws must protrude from the
lower enclosure lid.
7. Tighten all screws of the lower enclosure lid
using an Allen key (AF 3) in the order 1 to 6
(torque: 2 Nm ± 0.3 Nm).
Useful hint: If the screws fall out of the lower
enclosure lid, insert the short screw in the upper
middle hole and the five long screws in the other
holes.
8. If an ESS is used, the ESS has to be plugged in firmly. The ESS must be aligned parallel to and
flush with the enclosure.
9.
Risk of burns due to hot enclosure parts
• Wait 30 minutes for the enclosure to cool down.
