8 Recommissioning the Inverter
9. Tighten all 6 screws with an Allen key in the order 1
to 6 (AF 3, 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
hole at position 6, and the 5 short screws into the
other holes.
10. Set the DC load-break switch to position O so that
both mounting screws are visible.
11. Insert the DC load-break switch firmly into the recess on the inverter. During this process, the
DC load-break switch must still be in position O and aligned so that the screws are positioned
over the threads.
12. Tighten the 2 screws using an Allen key (AF 3,
torque: 2 Nm ± 0.2 Nm).
13. Turn the DC load-break switch of the inverter to
position I. If available, switch on the external DC
switch.
14. Switch on the circuit breaker of all 3 line conductors.
