Testing
Before reinstalling the top cover, the inverter should be tested to ensure it was assembled correctly.
To test an assembled inverter:
1.
Connect a DC power supply to the inverter. Use an appropriate voltage for the inverter under test (12
volts, 24 volts, etc.). 9-volt batteries may be used if a power supply is not available. For a 12-volt or
24-volt model, use three 9-volt batteries in series. For a 48-volt unit, use six 9-volt batteries in series.
2.
The inverter will go through a boot-up routine. The red LOW battery LED indicator will illuminate. It will
then be replaced by the yellow OK indicator and possibly the green FULL indicator.
3.
The fan, if plugged in, will come on. The fan does not need to be plugged in for testing, but the ERROR
indicator will illuminate if the fan is not present.
4.
The FX inverter is defaulted to the On state. The FXR inverter is defaulted to the Off state. Turn the FXR
inverter on with the MATE3 system display, or remove and replace the ON/OFF jumper as shown in the
Installation Manual. (Perform this with the FX inverter as needed, if it is not already on.)
5.
After a few seconds the inverter should produce AC voltage, accompanied by the green INVERTER
indicator. Check the output terminals with a DVM or voltmeter to confirm the presence of voltage. The
AC voltage reading should be appropriate for the inverter model.
6.
Once the inverter power-up sequence is confirmed, disconnect the DC power supply.
7.
The test is successful if the inverter completed each routine. If this did not occur, it may be necessary to
contact OutBack technical support for troubleshooting.
Completion
To finish reassembly:
1.
Connect the fan cable. See Figure 19 and also Figure 5 if necessary. In the FXR inverter, the cable should
be routed through notches in the AC and FET PCBA. Routing them elsewhere may pinch the cable.

2.
Place the top cover over the chassis so that the battery terminals protrude through the holes in the cover.

3.
Insert, but do not tighten the 6 screws that connect the top cover to the AC Assembly. See Figure 20.
4.
Reattach the red and black battery terminal nuts and tighten. Next tighten the 6 AC Assembly screws to
a torque value of 15 in-lb. See Figure 20.
