5. Connect the communication assembly with the
inverter. To do so, plug the ribbon cable to the
communication assembly and lock it.
6. Connect the DC connector to the inverter in its original position.
☑ The DC connectors snap into place.
7. Ensure that all DC connectors are securely in place.
8. Seal all unused DC inputs using the DC connectors with sealing plugs.
9. Insert the lower enclosure lid from above and flip it
down. The screws must protrude from the lower
enclosure lid.
10. Tighten all six screws with an Allen key (AF 3) in the
order 1 to 6 (torque: 2.0 Nm ± 0.3 Nm). By
tightening the screws in the prescribed order, you
avoid warping the enclosure 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.
11. Check the ESS for wear:
• Check the metal mounting tabs inside the ESS
for discoloration or damage.
If the metal mounting tabs show brown
discoloration or are damaged, order a new
ESS from SMA Solar Technology AG and have
the ESS replaced.
If the metal mounting tabs show no brown
discoloration or damage, the ESS is not worn
and can still be used.
12. Switch on the circuit breaker of all three line conductors.
13. If necessary, update the firmware of the communication assembly.
