Configuration
Set Configuration DIP Switches
Using a small tool, set the Configuration DIP Switches (located on the front panel, see diagram) to optimize Inverter/Charger operation
depending on your application. RV612UL and RV612ULH models include one set of four DIP Switches. All other models include an additional set
of four DIP switches to configure additional operational functions. Refer to the appropriate section to review the instructions for your spe-
cific model.

Group B Dip Switches (Not on 612 Models)
Group A DIP Switches (All Models)
Using a small tool, configure your Inverter/Charger by setting the four Group A DIP Switches (located on the front panel of your unit; see
diagram) as follows:
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. 8 for more information.

* Most of your connected appliances and 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 or DIP Switch #3 for
612 models) 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 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.

Select Load Sharing—OPTIONAL (Not on 612 Models)
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, all RV Inverter/Chargers (except models RV612UL and RV612ULH) 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 func-
tion 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.

Check specifications on for your unit's high- and low-charging
amp options. By setting on high charging, your batteries will
charge at maximum speed and your RV 12V DC system loads
will be well-supplied. When setting on low charging, you
lengthen the life of your batteries (especially smaller ones).
