1.0 INTRODUCTION
Features
The RC7 and RC7GS (Generator Start) are control units that allow remote
operation of any RV, Legend Series II, Tr uck Series II, and Mar iner inverter/
chargers rated from 2000 to 3000 watts.
NOTE: The generator start functions (GS) only apply to the RV Series inverter/
charger.
NOTE: The inverter and remote control must have software version 1.3x.
The RC7 and RC7GS feature:
• Simple menu driven programming for full control of all inverter/charger
functions
• A three-level menu to prevent accidental setting changes
• Meters to display voltage and current
• RJ11 phone jack connection to inverter
• Internal memory to retain inverter/charger menu settings even with a
loss of power
• An Intelligent battery fuelgauge displaying percent of battery charge
and the time left to run
• Error message and informative information displays used to optimize
system performance
• Remote ON/OFF inverter operation

All operating controls and indicators for the RC7 and RC7GS are located on
the front panel of the remote control. The inverter, software Rev. 1.3x must be
installed in both the inverter and remote. Refer to the instructions in the RVU-2
Software Upgrade Kit manual if an upgrade is required.
NOTE: The RC7 and RC7GS are identical remote controls; however, the RC7GS
has additional features for controlling a generator. These features are noted in
this manual as available for the “RC7GS only.”
On/Off Control
The inverter portion of the inverter/charger can be switched OFF or ON
using the remote control. The standby charger in the inverter is automatic and
always ready and available for charging whenever ac power is applied.
Meters
The RC7 and RC7GS remotes feature several meters that monitor the
operating conditions of the power center. These meters include: Average Shunt
Amps, Battery Voltage, Inverter-Charger Current, AC Output Voltage, AC Input
Amps, Battery Temperature, Transformer Temperature, FET Temperature, and
Estimated Battery Capacity.
Controls
The RC7 and RC7GS allow the inverter to be switched ON or OFF with the
press of a push-button on the remote. Both devices can be used to configure the
inverter/charger to the specific system and preferences including Battery
Capacity, Batter y Type, Charger Rate, Low Battery Cutout, Shore Power Amps,
External Shunt, Fuelgauge Cutout, and Display Contrast. In addition, the RC7GS
starts and stops of the genset automatically or manually, allows the setting of
generator make and model, sets a “quiet time” during which the genset will not
start automatically, and has manual overrides for auto gen start.
Status Monitoring
The RC7 and RC7GS remotes monitor operating conditions including: the
ac supply, inverter operation, charger operation, batter y condition, generator
condition (RC7GS only), Time Left to Run, and Time Left to Charge..

2.0 INSTALLATION
Installation Procedure:
1. Select an appropriate location to install the remote control.
2. Refer to the drawing (Figure 2) for hole and cutout dimensions or install
the remote in a standard double-gang outlet box.
3. Run the cable between the RC7 remote and the inverter/charger. Do NOT
use standard telephone cable.
4. Place the ON/OFF switch on the inverter to the OFF position and
disconnect the ac power.

4. Connect the communications cable into the RJ11 port on the inverter/
charger marked “REMOTE CONTROL.” Connect the other end of the
cable into the jack on the remote (Figure 3).
5. Secure the remote to the wall or outlet box using the appropriate screws
(4 required).
6. Wait for the LCD display to show the message “Waiting for AC.”
7. Place the ON/OFF switch on the inverter to the ON position.
NOTE: The remote will not operate the inverter if the inverter’s ON/OFF switch is
in the OFF position.
8. Reconnect the inverter to the ac source. After a brief delay, the remote
will display a system status message similar to Figure 4.

Front Panel Controls and Indicators
Front Panel
1. Indicators and Controls
The RC7 and RC7GS front panels contain LEDs, LCD display and pushbuttons for viewing status and system setup. All operating power for the remote
control is provided by the inverter/charger via the supplied cable.
2. Status LEDs
There are four LEDs on the front panel which light solid or flash during
operation, indicating the system’s status. Upon initial power-up of the inverter, all
LEDs will flash as the unit goes through a self-test. After the initial power-up test
completes, the LEDs will indicate the current state of the inverter and charger.
Use these LEDs along with the LCD display for detailed system status.

The green Inverter LED indicates the inverter is switched ON and ready to
provide backup power. If there is no ac power, the inverter LED will be ON solid,
indicating that the inverter/charger is in the inverter (ON) mode.

5. Batt. Full LED
The Batt. Full LED indicates the state of charge on the batteries. This LED
will not illuminate until the batteries have charged up to at least 90%. The
duration of the LED’s ON time will increase until the batteries reach 100%, which
at that time, the LED will be ON solid. In the inverter mode, the OFF time
duration of the LED will increase until the batteries discharge to below 90% at
which time the LED will extinguish.
Batt. Full LED Other LEDs or Devices Meaning
Solid Battery Fully Charged (100%)
Flashing Battery Charged 90% or
higher
OFF Battery Below 90% Charge
6. Error LED
The Error LED indicates that there is a problem with the inverter/charger or
batteries. Check the LCD display to find and correct the nature of the problem.

Push-button Controls
a. On/Off
The On/Off push-button controls the inverter section of the inverter/charger.
Press this button once to turn the inverter ON or OFF. The charger section of the
inverter is not affected by this function and maintains the batteries whenever ac
power is present. On RC7GS models, this push-button also controls the
generator. Refer to Generator Start/Stop. Use this control when you do not want
the inverter to supply backup power in the event of an ac line failure. Ac output
power is available only as long as the ac line is present.
NOTE: Pressing this push-button disables the inverter function. Ac backup power
will NOT be available during a utility outage. The green INVERTER LED must be
flashing (with ac utility applied), indicating the inverter is in a ready state.
Pressing this push-button while the green LED is ON solid (indicating backup
mode), will cause the loss of the inverter output.

Initial LCD Display Item
The following menu items appear in the exact sequence they appear on the
RC7. Refer to pages 36-37 for the complete menu structure.
1. Search Sense
Search Sense enables or disables the power-saving “search” mode logic
circuitry. Refer to the inverter’s Operator’s manual for a complete description of
the Search Sense mode.
To configure the Search Sense mode, use the RIGHT arrow push-button
(Settings), to scroll to the desired setting. The default setting is
Defeat
.
Defeat disables the Search Sense function. The remaining selections,
specify the minimum wattage load that must be present on the inverter to qualify
as a load and bring the inverter out of the search mode. After selecting, press
