Example of three-phase, input and output wired, with reinforced phase
Highlight(s):
This installation allows a three-phase supply with a reinforced phase The
reinforced phase may be incorporated on two or even three inverters in parallel. The
protection device at the output on which 2 or 3 Xtenders are cabled must be calibrated
according to the sum of the maximum currents of the devices in parallel.
The comments for fig. 12 to 13 are valid.

Example of cabling of 9 Xtenders in three-phase and parallel – AC part
Special feature: In fixed high power installations, it is advised that a shared neutral be
retained, distributed to all parties in the grid (see (C))
The comments for figs. 12 to 15 are valid.

Connection of remote controls RCC-02/03
At a Xtender or at a system with several Xtender maximally 3 remote controls can be
attached.

Elem. Description
Comment
a
RCC-02/03
remote control
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.
27.
b Battery
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. 13.
e
Communication
s cable
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.
f
Protection
devices
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 section used.
If the negative pole of the battery is not earthed, it must also be
protected by such a device.

k
Wind-powered
or/and micro-
hydro
generator
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.
L
m Solar
generator
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.
r
Entry command
control via dry
contact
A control device may be connected to the terminals (7) of the
Xtender. See chapter 6.2.12 – p.25.
The length of the connection cable must not exceed 5 m.
t
BTS-01
temperature
sensor
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.28
