2. Ensure that the grounding conductor in the inverter is correctly connected and functions
properly.
3. Position the enclosure lid of the AC-Connection Unit on the AC-Connection Unit and first
tighten the upper-left and lower-right screws, and then the remaining screws crosswise (TX 25,
torque: 6 Nm (53 in-lb)).
4. Connect the DC connector to the inverter in its original position.
☑ The DC connectors snap into place.
5. Ensure that all DC connectors are securely in place.
6. For STP 50-US-40 / STP 33-US-41 / STP 50-US-41 / STP 62-US-41: Turn the AC load-break

9. Turn the DC load-break switch of the inverter to
position I.
10. If the green LED is still flashing, the conditions for activating feed-in operation are not yet met.
As soon as the conditions for feed-in operation are met, the inverter starts with feed-in
operation and, depending on the available power, the green LED will light up continuously or
it will pulse.
11. If the red LED lights up, an event has occurred. Find out which event has occurred and, if
necessary, initiate countermeasures.
