Procedure; Removing The Inverter Module(S) - ABB ACS880-37 Hardware Manual

multiple inverter cubicles (ie. two cubicles of two modules each), make sure that the motor
cabling is identical for both cubicles.

Procedure



Removing the inverter module(s)

To allow more room for cabling work, the inverter module can be removed completely
instead of only the fan carriage.
Refer to the drawings below.
WARNING! Obey the instructions in chapter
ignore them, injury or death, or damage to the equipment can occur.
1. Do the steps in section
work.
2. Open the cubicle door.
3. Remove the shroud at the top of the cubicle.
4. Detach the terminal block [X50] at the top of the module.
5. Detach the DC busbars from the module. Make note of the order and position of the
screws and washers.
6. Detach the wiring connected to the terminals on the front of the module (including fiber
optic cabling). Move the disconnected wiring aside.
7. 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 module extraction/installation ramp with plinth heights
over 50 mm.
8. Remove the two screws at the bottom front of the module.
WARNING! Before you proceed, make sure the cabinet is level, or chock the
wheels of the module.
9. Remove the two screws at the top front of the module.
10. 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.
11. 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.
12. Repeat the procedure for the other inverter modules (if any).
13. Frame 1×R8i + 1×R8i only: Repeat the procedure for the supply module.
14. Frame 1×R8i + 1×R8i only: Remove the LCL filter module as described on page 168.
