9. Unscrew all ten screws of the enclosure lid of the
DC connection unit with a Torx screwdriver (TX25)
and remove the enclosure lid towards the front.

10. Set the screws and the enclosure lid aside and store safely.
11. Remove all connection cables from the communication assembly and pull out the connection
cables out of the DC connection unit.
12. Remove all conduits with conductors from the inverter. To do this, screw the conduit fittings out
of the enclosure openings from the inside.
13. When the DC surge arresters are inserted, pull the surge arresters out of the slots. To do so,
squeeze the grooved areas on the left and right sides of the surge arrester.
14. Position the enclosure lid of the DC connection unit
on the DC connection unit and first tighten the
upper-left and lower-right screws, and then the
remaining screws crosswise using a Torx screwdriver
(TX25) (torque: 6Nm (53in-lb)).

15. Screw all four transport handles as far as they will
go into the taps on the right- and left-hand side until
they lie flush with the enclosure. When doing so,
ensure that the transport handles are screwed into
the taps so that they are perfectly straight. If the
transport handles are not screwed in straight, this
can make it more difficult or even impossible to
unscrew them later on and can damage the taps to
the extent that transport handles can no longer be
screwed into them.

16. Insert a screwdriver into the holes in the transport
handle and turn the screwdriver through 90°. This
ensures that the transport handles are securely
tightened.
