9 Decommissioning the Inverter
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 (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.
17. To remove the feet or profile rails, lay the inverter carefully on the AC-Connection Unit side.
18. If the inverter is to be stored or shipped, pack the inverter in its original packaging.
• Place the lower part of the original packaging with padding on the pallet
• Place the inverter with padding on the pallet. For this purpose, put the AC-Connection
Unit side of the inverter on top of the padding.
