1FOREWORD
This manual contains information relating to the functioning of the RCC-02 and RCC-03 remote
controls.
The use of certain functions sometimes requires advanced knowledge in various fields. This manual
cannot provide this. In case of doubt, please contact your reseller or installer.
1.1 CONVENTIONS
This symbol is used to indicate the presence of a dangerous voltage that is sufficient
to constitute a risk of electric shock.
This symbol is used to indicate a risk of material damage.
This symbol is used to indicate information that is important or which serves to optimize
your system.
Terminology:
The following terms are used in the manual to provide greater clarity:
RCC is used to indicate the remote control RCC-02 or RCC-03 if the description applies to both
models.
Installation is used to describe all the electrical equipment connected together. This may be the
source (public grid or generator), and one or more Xtender(s) with or without remote control as well
as electrical consumers.
System is used to describe the entirety of Xtenders with or without remote control.
Xtender or combi is used to describe one or more Xtender(s) connected together.
1.2 PRODUCT RECYCLING
The RCC remote control conforms to the European directive 2011/65/EU on hazardous substances
and does not contain the following elements: lead, cadmium, mercury, hexavalent chrome, PBB or

3INTRODUCTION
Congratulations! The purchase of an RCC remote control offers you unlimited access to the various
functions of the devices in the Xtender series. Numerous configurations that can now be accessed
allow you to optimize the operation of the installation. Despite all these options, the Xtender works
on a simple basis.
Different figure scenarios as well as associated configurations are presented at the end of this
manual.
The manual for the RCC remote control is divided into several distinct parts:
The first part (page 11 to 26) is dedicated to the adjustments of the RCC remote control, whether this
is the language used or the clock, which are sometimes necessary for the whole installation to work
well.
The second part (page 27 to 34) is concerned with immediate information on the installation. This
gives access to the electric values such as the battery voltage, inverter load and many more.
The third part (page 35 to 35) shows the functions for saving events occurring in the installation. This
may be necessary for diagnosing a weakness or simply to check that the whole unit is working well
during its whole service life.
The fourth part (page 36 to 74), which is more technical, presents various options for configuring the
Xtender.
Do not change the configurations except when you have the technical knowledge; otherwise, the
operation of the installation could at risk or installation itself could be partly damaged.
The fifth part (page 76 to 79)consists of more general items like information about the system, the
updating process or examples of applications.
The sixth part (page 81 to 94) consists of two tables with all "Remote control" and "Inverter"
parameters. These tables, which follow the same hierarchical order as in the remote control, give an
overview on all adjustable parameters and also information about the factory settings.
3.1 MODELS CONCERNED
The RCC remote control may be connected to any Xtender, VarioTrack or VarioString the use of
which is clearly detailed in its operating instructions.
3.2 CONTROLS AND INDICATORS
The RCC remote control is equipped with four operating keys as well as a graphic display
with back-lighting. The function of the keys may change according to the context of
utilisation and a reminder of the function in progress is given at the right of the display.
Generally the keys UP and DOWN are used to alter values or options relating to what is on
the display and the two central keys are used to access, confirm or quit the item shown.
If the back-lighting function is activated, pressing one of the keys starts it up.

3.3 SD CARD
The RCC remote control is equipped with an SD (Secure Digital)-type memory
card reader. This card (supplied) is used for various functions described in this
manual. It allows, amongst others, the following functions: recording statistics,
updates, backups or restoration of configurations or adjustments. The filing
system used for the data is the FAT system (FAT16).
This card can be read using any standard SD
card reader.
As far as the RCC-03 is concerned, the use of the
SD card requires removing the remote control
since the access to the SD lies behind.
The system of the card reading is compatible with the following types of cards:
SD
SD HC
The system of the card reading is incompatible with the following types of cards:
SD XC
Cards of more than 32 GB

4CONNECTION
The RCC-02 remote control must be firmly fastened using 3 screws on a flat support. The remote
control RCC-03 is meant to be integrated. It must be mounted by means of 4 screws (not supplied)
on a flat place without any mechanical constraints to the front plate. Once the RCC remote control
is fastened it can be connected to the inverter using the authorized cable only. If the cable is
damaged or if a socket is detached, the cable must not be connected since this can lead the whole
installation to malfunction.
A maximum of 3 remote controls can be connected to one unit.
4.1 SERIES CONNECTION
Devices in the Xtender series are equipped with a proprietary communication bus for data
exchange, configuration and updating of the system. Series connection is obtained by linking the
devices with the provided communication cables. This way a serial bus is created where the
terminations must be activated on the units on both ends.
Each device is equipped with a switch offering to choose between open "O" and terminated "T". By
default all terminations are activated on each Studer Innotec product. The devices at the end of the
line must be set on "T" (one cable) and all the others on "O" (two cables).
A wrong setting of the terminations can lead to an erratic running of the
installation or impede its updating.
The remote control must never be placed in between two devices connected
to the battery (Xtender, VarioTrack, VarioString).
Exemple of an installation with indicated terminations.
