(GFCIs) A GFCI is a device that de-energizes a circuit when a current to ground
exceeds a specified value that is less than that required to blow the circuit
breaker. GFCIs are intended to protect people from electric shocks and
are usually required in wet or damp locations.
Installations in marine and recreational vehicles require GFCI protection
of branch circuits connected to the AC output of the
Freedom HF .
The modified sine wave output of the Freedom HF is not equivalent to the
waveform provided by electric utilities, and compliance with UL and
CSA standards requires that Xantrex test and recommend specific GFCIs
that will work correctly with the
Freedom HF .
For more information about GFCIs, see the application note "Using GFCI
Receptacles on Xantrex Inverters and Inverter/Chargers" in the Document
Library at www.xantrex.com/support.
