6 Disassembling the defective AC power controller assembly
11. Loosen and remove the module screw with a Torx
screwdriver (TX20).
12. Remove the cover of the power module and store it safely.
13.
The power module may slip while the AC power controller assembly is
being removed.
The power module is located below the AC power controller assembly, and sticks in place
solely by means of the thermal grease on the inverter enclosure. If the AC power controller
assembly is removed without due care, the power module may slip.
• To prevent the power module from slipping, screw the module screw back into the
power module slightly without the cover.
14. Loosen the six screws of the defective AC power controller assembly with a Torx screwdriver
(TX20) and remove them.
15. Carefully remove the defective AC power controller assembly from the inverter enclosure.
16. If no ferrite ring is included with the new AC power
controller assembly, remove the ferrite ring from the
DC link connection cable of the defective AC power
controller assembly and connect it to the DC link
connection cable of the new AC power controller
assembly using a cable tie.
