3. Tighten all six screws of the lower enclosure lid
using an Allen key (AF 3) in the order 1 to 6
(torque: 2.0 Nm (17.7 in-lb.)). Make sure that the
ribbon cable of the communication assembly is not
clamped. By tightening the screws in the prescribed
order, you avoid warping the lid, which would keep
it from sealing correctly. Tip: If the screws fall out of
the lower enclosure lid, insert the long screw into the
lower middle hole and the five short screws into the
other holes.
4. Pack the defective inverter in the packaging of the replacement device and arrange with SMA
for it to be picked up.
