Interrupting this connection in a multi-unit system will lead to the stoppage – after 5 seconds – of
all the units in the system.
Various application examples are described from fig. 12 to fig. 19.
It is important to read and adhere to the descriptions associated with each of the figures
mentioned above
In configurations carrying several Xtenders, each unit is controlled independently using the
ON/OFF push button (41). When the on/off control is given via the RCC-02/03 remote control, it is
applied simultaneously to all units.
6.3.1 T HREE - PHASE SYSTEM
Three Xtenders of the same type can be used and combined in order to establish a three-phase
grid. An example of Fehler! Verweisquelle konnte nicht gefunden werden. is given at figs. 13.-
14.
When 3 Xtenders are cabled to form a three-phase grid, the cabled phases at the input determine
the jumper position for selecting the phase (10). It is vital to determine and select the phase for
each Xtender. If the grid is not available at the input of the master unit (phase 1) all the units of
the system pass into inverter mode. If only a single-phase source is available, it will be connected
to phase 1. The other two phases will therefore be supplied by the other two working units in
inverter mode.
6.3.2 I NCREASING THE POWER AND CONNECTION IN PARALLEL
Up to three Xtenders can be cabled in parallel in order to increase the system’s rated power
output. In this configuration, all the ACin inputs of the Xtender must be cabled. One of the units
functions as master and will decide on the operation or suspension of the units in parallel
according to the consumer’s power demand. The yield of the installation is therefore still optimal.
An example of parallel connection is given in fig.12. and the comments on p. 30.
6.3.3 C OMBINED SYSTEM
It is possible to combine a three-phase system with one or several phases made up of 2 or 3
Xtenders in parallel. An example of cabling is given at fig. 15.
It is therefore possible to combine up to nine Xtenders by running three Xtenders parallel in a
three-phase grid. An example of cabling is given in figs. 16 to 18 and the comments on p. 31.
6.4 Accessories
6.4.1 C ONTROL CENTRE AND RCC-02, RCC-03 ( REMOTE CONTROL ) DISPLAY
An RCC-02/03 remote display and programming unit can be optionally connected to the Xtender
via one of the two RJ45-8-type “Com. Bus” (3) connectors.
These connectors may only be used for connecting a CAN-ST compatible accessory, excluding
any other connection such as LAN, Ethernet, ISDN, etc.
The RCC-02/03 control centre is vital for modifying device configurations.
It also allows the following functions:
• Display of function synopsis
• Display of the measured operational values (current / voltage / power output, etc.)
• Updating of software or implementation of customised software
• Storage of inverter configuration
• Updating of inverter configurations
• Storage of error message history
