Removing the inverter module(s)

Refer to the drawings below.
WARNING! Obey the safety instructions given in Safety instructions for
ACS880 multidrive cabinets and modules (3AUA0000102301 [English]).
If you ignore them, injury or death, or damage to the equipment can
occur.
Note: The illustrations represent a frame 2×R8i inverter cubicle with option +F286 (DC
switch/disconnector). On units without +F286, the DC busbars are oriented differently, but
the procedure is otherwise the same.
1. Do the steps in section
work.
2. Remove the shroud at the top part of the cubicle.
3. Detach the terminal block [X50] at the top of the module.
4. Detach the DC busbars from the module. Make note of the order and position of the
screws and washers.
5. Detach the fiber optic cables. Also detach the wiring connected to terminals X51...X53
(if any). Move the disconnected wiring aside.
6. Attach the module extraction/installation ramp (included) to the base of the cabinet so
that the tabs on the mounting bracket enter the slots on the ramp. WARNING! Do not
use the ramp included in the drive delivery with plinth heights over 50 mm.
7. Remove the two screws at the bottom front of the module.
8. Remove the two screws at the top front of the module. WARNING! If the cabinet is not
level, the module may move once the screws are removed.
9. Pull the module carefully out along the ramp. While pulling on the handle with your
right hand, keep a constant pressure with one foot on the base of the module to
prevent the module from falling on its back.
10. Move the module into a safe location outside the immediate work area and make sure
it cannot topple over. Chock the wheels of the module if the floor is not completely
level.
11. Repeat the procedure for the other inverter modules (if any).
