11. Ensure that no voltage is present at the DC inputs on
the inverter using a suitable measuring device.
12. Unscrew (TX25) all ten screws of the enclosure lid of
the AC-Connection Unit and remove the enclosure
lid carefully towards the front.
13. Set the screws and the enclosure lid aside and store safely.
14. Ensure there is no voltage on the AC terminal block between L1 and N, L2 and N, and L3 and
N using a suitable measuring device. To do so, insert the test probe (maximum diameter:
2.5 mm (0.078 in)) into the measuring points of the respective terminal blocks.
15. Ensure there is no voltage on the AC terminal block between L1 and PE, L2 and PE, and L3
and PE using a suitable measuring device. To do so, insert the test probe (maximum diameter:
