NOTE: For low power system shut down
mode, both the INVERT and CHARGE LEDs
must be OFF.
Testing for backfeed. If a backfeed
condition is indicated, disconnect from shore
power and disconnect the AC output wires on
the inverter. Make sure the inverter is OFF.
Apply shore power and measure for
voltage between the black and white wires that
were attached to the inverter output feeding the
electrical panel or loads, not the inverter output
wires. If there is voltage on these wires, a
back-feed condition exists and must be
corrected or damage will result.
3. Test the battery charger function:
With shore power applied and the
transfer switch engaged, the battery charger
should be in operation. The CHARGE LED will
blink for 8 seconds. After the 8 seconds, the
unit will enter the charge mode and the LED
will be illuminated. (NOTE: When using
Temperature Sensitive Charging, this time may
be longer.)
NOTE: When AC is available, the unit will
automatically default to charge mode without
the operator setting the unit in CHARGE mode.
It is necessary to press the CHARGE switch
OFF, if you do not want to charge.
Verify the charger is working by using a
volt meter. The battery voltage should gradually
increase. If using a Remote Control Panel, the
DC Amps LED indicates the current the
charger is putting out and the DC Volts LED
indicates an increase in battery voltage.
INSTALLATION
Turn the INVERT ON, the green LED
should blink. Remove shore power and the
inverter should automatically pick up the AC
load when shore power is removed.
Repeat the test for transfer and battery
charger with the generator if you have one.
Congratulations, you have completed a
successful installation.
