Assembly
The order of assembly depicted here is:
1.
FET PCBA
2.
AC PCBA
3.
Control PCBA
If the FET and or AC boards do not need to be replaced or have not been removed, the installer
may ignore these steps and proceed through the steps that are required. The installer should then
proceed to the testing steps, which begin on page 11.
To assemble the inverter:
1.
Check the replacement FET PCBA to see if a thermistor clip was installed. (See Figure 12.) If one is
present, remove it and discard.
2.
Guide the FET PCBA into the proper slot of the chassis; lower it only halfway down. Plug the green
thermistor wire from the transformer into the FET PCBA. (See Figure 12 for the location of this
connector.) Push the FET PCBA all the way down into the chassis.
IMPORTANT:
Ensure that the AC wires from the transformer (see step 5) are routed through the gap
on the bottom of the FET PCBA. Routing them elsewhere may pinch the wires and
could cause the inverter to fail.
