compatible, replace the connector in the new module. Use the connector from the old
module, or order suitable connector from ABB. Refer to Connector replacement guide,
auxiliary power supply for ACS880-104 R8i, ACS880-304 D8T and D7T
(3AXD50001060015 [English]) or Connector replacement guide, auxiliary power supply
for ACS880-104 R8i with +C183, ACS880-304 D8T with +C183 (3AXD50001060022
[English]).
If you replace a module with a new one, make sure that the new module has the same
type code as the old one.
1. Make sure there are no tools, debris or any other foreign objects in the cubicle.
2. If not already in place, 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.
3. Push the module up the ramp and back into the cubicle.
• Keep your fingers away from the edge of the module front plate to avoid
pinching.
• Keep a constant pressure with one foot on the base of the module to prevent
the module from falling on its back.
4. Attach the top front of the module with two screws. Tighten to 22 N·m (16 lbf·ft).
5. Attach the bottom front of the module with two screws. Tighten to 22 N·m
(16 lbf·ft).
6. Remove the ramp.
7. Drives with option +C121 (Marine construction) or +C180 (Seismic design):
a. Remove the bolts holding the fan carriage (two bolts per module).
WARNING! The module retaining screws (two at top, two at bottom
per module) must be in place before removing these screws. Otherwise,
the parts of the module can become separated and cause injury or
damage.
b. Install the transverse retaining bracket. At the ends of the bracket, tighten
the screws to 9 N·m [6.6 lbf·ft]. Install the fan carriage bolts removed at
previous step, and tighten to 22 N·m (16 lbf·ft).
8. Attach the DC busbars to the module. Tighten to 70 N·m (52 lbf·ft). See Use of
fasteners in cable lug connections (page 61).
9. Connect terminal block [X50] at the top of the module.
