Note: The GFCI contains a lockout feature that
prevents a RESET if there is no power being supplied
to it. Therefore, make sure to force By-Pass mode
or do not have either the PS0 or PS2 setting when in
Inverter mode, before resetting.

Condition
Normal condition when in
Search mode. The load
connected must be below the
AC load sense threshold of
10W; so the power output will
be pulsed every 10 sec for
checking the load.
Verify the error condition,
and then make the necessary
correction.
AC Output L1/N1 terminals
are connected directly to
the inverter's output. The
terminals are not under the
tripping infl uence of either
the GFCI or the 20A thermal
breaker on the unit.
Turn the unit on by pressing
the Power button (when the
unit is in Inverter mode, or
in By-Pass mode if the PS4
parameter is set). Otherwise,
the unit should always
automatically turn on at the
moment AC input power is
connected.
Check the battery DC fuse,
the disconnect switch (if
installed), and the AC input
source. The AC input branch
breaker is either tripped or
turned off .
Check the AC load for a
ground fault, and reset the
GFCI. Make sure the loads
do not have the neutral and
ground bonded.
If no load plugged in to GFCI,
there may be humidity inside.
Try drying with a hairdryer.
Ensure unit is in a dry area.
Check loads and reset the 20A
thermal breaker.
