Configuration
Set Configuration DIP Switches
Using a small tool, set the Configuration DIP Switches (located on the front panel of your unit, see diagram) to optimize Inverter/Charger
operation depending on your application.
Group A DIP Switches
Select Battery Type—REQUIRED

CAUTION: The Battery Type DIP Switch setting must
match the type of batteries you connect, or your batteries
may be degraded or damaged over an extended period of
time. See "Battery Selection," for more information.

* Most of your connected appliances and equipment will perform adequately when your Inverter/Charger's High AC Input Voltage Point is left in the factory setting and its Low AC Voltage Input
Point is set to 182V. However, if the unit frequently switches to battery power due to momentary high/low line voltage swings that would have little effect on equipment operation, you may wish to
adjust these settings. By increasing the High AC Voltage Point and/or decreasing the Low AC Voltage Point, you will reduce the number of times your unit switches to battery due to voltage swings.
Group B DIP Switches

Select Load Sharing—OPTIONAL
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 four 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 on the next page show how to set your DIP Switches to determine how heavy the
connected load can be on your Inverter/Charger before charger-limiting begins.
