Using GFCI outlet
The GFCI (Ground Fault Interrupter) must be tested before
each use. To test:
1. Turn the inverter oN.
2. Push the "ReSeT" button located on the GFCI receptacle,
first to assure normal GFCI operation.
3. Plug a nightlight (with an "oN/oFF" switch) or other
product (such as a lamp) into the GFCI receptacle and
turn the product "oN."
4. Push the "TeST" button located on the GFCI receptacle.
The nightlight or other product should go "oFF."
5. Push the "ReSeT" button, again. The light or other
product should go "oN" again.
Note: If the light or other product remains "oN" when
the "TeST" button is pushed, the GFCI is not working
properly and should not be used. Call Customer Service.
The PI-1500 includes two, "GFCI " (Ground Fault Circuit
Interrupter) outlets located on the right side of the invert-
er. The purpose of a GFCI outlet is to quickly stop the
flow of electricity in the event a ground fault occurs on the
device plugged into the inverter’s GFCI outlet. Use only a
3-prong grounded plug when using the GFCI outlet.
Note: The GFCI outlet could have been shipped in the
“tripped” position. It needs to be “reset” to ensure safe
electrical operation. The inverter needs to be oN, con-
nected to a power source and a device plugged into the
