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 sect. 9.1 – p. 35.
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 sect.
4.3.1 – p. 18.
See sect. 4.5.5 – p. 22
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.
A fuse-type device, thermal circuit breaker or magnetic-thermal circuit
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 cross-section used.
If the negative pole of the battery is not earthed, it must also be protected
by such a device.

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
sect. 7.7 – p. 31. On XTM and XTS this input is available on a separate
(external) device RCM-10 (see sect. 9.3.1- p. 36).
The sensor is placed in the immediate proximity to the battery. If the
installation comprises several Xtenders, a single sensor is connected to one
of the units. See sect. 9.2 - p. 36.
