Configuration
Group B DIP Switches
B2 Select AC Sharing—OPTIONAL
B1
Your Inverter/Charger features a high-output battery charger that can draw a significant amount of AC power from your utility source or
generator when charging at its maximum rate. If your unit is supplying its full AC power rating to its connected heavy electrical loads at the
same time as this high charging occurs, the AC input circuit breaker could trip, resulting in the complete shut off of pass-through utility power.
To reduce the chance of tripping this breaker, Inverter/Chargers may be set to automatically limit the charger output. This keeps the sum of the
unit's AC load and charge power within the circuit breaker rating. This charger-limiting function has two settings, allowing you to reduce
the charger's draw lower and lower, as needed, if the AC input circuit breaker keeps tripping under the normal AC loads of devices you have
connected downline from the unit. The figures show how to set your DIP Switches for charger-limiting.
Select Battery Charger-Limiting Points—OPTIONAL
"Most Limiting" (#B2 & #B1 Up):
Charger-limiting takes effect the moment
any 120V AC load is applied; charger
output falls gradually from full output at
no 120V load passing through to no output
at full load.
Select Equalize Battery Charge—OPTIONAL
B3
This DIP Switch is momentarily engaged
to begin the process of equalizing the
charge state of your battery's cells by time-
limited overcharge of all cells. This can
extend the useful life of certain types of
batteries; consult with your battery's manufacturer to determine if
your batteries could benefit from this process. The charge
equalization process is automatic; once started, it can only be
stopped by removing the input power.
Set Battery Charging Amps—OPTIONAL
B4
Check the nameplate of your unit for the
available high- and low-charging amp
options. By setting on high charging, your
batteries will charge at maximum speed and
the 12V DC system loads of your RV will be
well supplied. When setting on low charging, you lengthen the life
of your batteries (especially smaller ones).

"Less Limiting" (#B2 Up & #B1 Down):
Charger-limiting
Inverter/Charger's load reaches 33% of the
Inverter/Charger's load rating. Charger
output falls gradually from full output at
33% of the Inverter/Charger's load rating to about 40% of full output
at full load.
Setting Procedure
• Move to "Equalize" (DOWN) position for three seconds.
Reset
• Move to "Reset" (UP) position and leave it there. This is the
factory default setting.
CAUTION: Do not leave DIP switch #B3 in the down position after beginning process. Battery
charge equalization should only be performed in strict accordance with the battery manufacturer's
instructions and specifications.
