Shipping the Defective Inverter
1. If necessary, position the upper enclosure lid
with the six screws and conical spring washers
on the enclosure and tighten it using an Allen
key (AF 4) in the order 1 to 6 (torque: 6 Nm ±
0.3 Nm).
2. Insert the lower enclosure lid from above and flip it down. The screws must protrude from the
lower enclosure lid.
3. Tighten all six screws in the lower enclosure lid
with an Allen key (AF 3) in the order 1 to 6
(torque: 2 Nm ± 0.3 Nm). 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
Solar Technology AG for it to be picked up.
