Testing the GFCI-protected AC outlet
The outlet on the XPower 450 is a Ground Fault Circuit Interrupter (GFCI) outlet. A GFCI outlet protects you against hazardous electrical shocks that could be caused by dampness, faulty mechanism, worn insulation, and so on. You might still feel shock, but the GFCI should cut it off quickly enough so an adult in normal health is not seriously injured (infants and small children may still be affected).
Test the GFCI periodically to make sure it is operating correctly.
To test the GFCI protection:
1.Switch the power inverter “ON”.
2.Plug a test lamp into the outlet.
3.Push the “TEST” button.
The “RESET” button should pop out and the power should turn off (the lamp should go out). If the lamp remains lit, or if the “RESET” button does not pop out, take the product back to the store where it was purchased and get a replacement or contact Xantrex for under warranty replacement.
If the GFCI trips by itself at any time, reset it and perform the preceding test.
