Extracting the module from the cubicle
1. Read and repeat the steps in section Safety instructions on page 115.
2. Open the door of the supply and inverter unit cubicle (see section Cabling
direction starting on page 33).
3. Remove any shrouds that protect the busbars and cable entries.
4. Open the transparent cover on the front of the module and disconnect the fibre
optic cables. Move the cables aside.
5. Remove the L-shaped DC busbars on top of the module – be careful not to drop
the screws or busbars inside the module.
6. Disconnect the terminal block (X50) next to the DC busbars.
7. At the base of the module, loosen the two fastening screws (7a) but leave them
in place; lift the bracket (7b) into the up position. (Loosen the locking screws on
the sides of the bracket a bit, too, if necessary.)
8. Insert the module pull-out ramp under the two screws at the base of the module
and tighten.
WARNING! Do not use the ramp which is supplied with the drive with heights over
50 mm (the standard plinth height of ABB cabinets). The ramp is designed for a
plinth height of 50 mm.
9. Remove the two module fastening screws at the top.
10. Pull the module carefully out of the cubicle along the ramp.
WARNING! Make sure that the wires do not catch. While pulling on the handle, keep
a constant pressure with one foot on the base of the module to prevent the module
from falling on its back. Use safety shoes with metal toe cap to avoid foot injury.
11. Extend the support legs of the module. Keep the legs extended until the module
is about to be inserted back into the cubicle.
