Note: Before you start replacing the supply module, make sure that the connector at
the end of the auxiliary power supply cable in the cabinet is compatible with the
counterpart in the module. Black connector is compatible only with the black
counterpart, and gray connector only with the gray counterpart. If the connectors are
not compatible, replace the connector in the new module. Use the connector in the
old module, or order suitable connector from ABB. Refer to +V112 connector
replacement guide for ACS880-x04 R8i/D8T/D7T module change (3AXD50001060015
[English]).
Obey these instructions for replacing the module. Refer to the drawings below.

3. Undo the screws of the shroud in the upper part of the cubicle. Lift and remove
the shroud.
4. Unplug the wires and optic cables from the module, and move them aside.
5. Attach the module extraction/installation ramp (included) to the base of the

6. Remove the bolts holding the DC busbars.
7. Remove the module fastening screws at the top of the module.
8. Remove the module fastening screws at the bottom of the module.
9. Pull the module carefully out of the cabinet along the ramp.
10. To reinsert the module into the cubicle:
• Push the module back in and fasten. Tighten the fastening screws of the
module to 22 N·m (16.2 lbf·ft) and the fastening bolts of the DC output busbars
to 70 N·m (52 lbf·ft).
• Reconnect the wires and fiber optic cables to the module.
• Reinstall the shrouding.
