• Testing for backfeed. If a backfeed
condition is indicated, disconnect from
shorepower and disconnect the AC output
wires on the inverter. Make sure the inverter is
OFF. Apply shorepower and measure for volt-
age 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
backfeed condition exists and must be corrected
or damage will result.
3. Test the battery charger function:
• With shorepower applied and the transfer
switch engaged, the battery charger should be
in operation. The CHARGE LED will blink for
eight seconds. After the eight 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 auto-
matically default to charge mode without the
operator setting the unit in CHARGE mode. If
you do not want to charge, it is necessary to
press the CHARGE switch OFF.
Verify the charger is working by using a
voltmeter. 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 shorepower and the
inverter should automatically pick up the AC load.
Repeat the test for transfer and battery charger
with the generator if you have one.
Congratulations, you have completed a
successful installation.
NOTE: For low power system shut down
mode, both the INVERT and CHARGE LEDs
must be OFF.
