13 Decommissioning the Inverter
11. Remove all connection cables from the
communication assembly and pull out the
connection cables out of the DC connection unit.
12. Remove all cable glands from the inverter. To do so, unscrew the counter nut from inside and
remove the cable glad from the enclosure opening.
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).
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.
