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," p. 7 for more information.

Gel Cell (Sealed) Battery

Wet Cell (Vented) Battery

Select Low AC Input Voltage Point for Switching to

Battery—OPTIONAL*

Voltage

105V

95V

85V

75V

* Most of your connected equipment will perform adequately when your Inverter/Charger's High AC Input Voltage Point (DIP Switch #2 of Group A) is set to 135V and its Low AC Voltage Input

Point (DIP Switches #3 and #4 of Group A) are set to 95V. However, if the unit frequently switches to battery power due to momentary high/low line voltage swings that would have little effect on equip-

ment 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.
