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.)). By tightening the
screws in the prescribed order, you avoid
warping the lid, which would keep it from
sealing correctly.
Useful hint: 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.
