Installation and operating Instructions
Comment
This device allows complete configuration of the installation as well as
displaying the system behaviour. It is recommended but not
necessary for the installation to function well. See chapter 6.4.1 – p.
23.
The battery capacity is constituted according to figures 5a to 6d
based on the required voltage. Note: It is vital that the voltage and the
polarity of the battery be checked before connecting to the inverter.
An overload or incorrect polarity could seriously damage the Xtender.
Correct dimensioning of the batteries is essential for trouble free
operation of the system. See chapter 4.3.1 – p. 11.
Communications cable. Only an original cable supplied by Studer
Innotec may be used. The total length of the communications cable
must not exceed 100 m for 3 x RCC-02/03 or 300 m for a single
RCC-02/03.
breaker (see fig. 8a) must be installed on at least one of the two
battery conductors. It will ideally be placed on the positive pole of the
battery and as close as possible to this. The calibre of the device is
selected according to the cable section used.
If the negative pole of the battery is not earthed, it must also be
protected by such a device.

Negative pole of the battery
One or more wind-powered generators or/and micro-hydro with their
own regulation system may be used to directly charge the battery. Its
dimensioning does not depend on the Xtender and does not interfere
with it.
One or more solar-powered generators with their own regulation
system may be used to directly charge the battery. Its dimensioning
does not depend on the Xtender and does not interfere with it.
A control device may be connected to the terminals (7) of the
Xtender. See chapter 6.2.12 – p. 21.
The length of the connection cable must not exceed 5 m.
The sensor is placed in immediate proximity to the battery. If the
installation comprises several Xtenders, a single sensor is connected
to one of the units. See chap. 6.4.2 p.24
