POWER-UP OF THE EQUIPMENT

It is imperative that the closing cover for the connection compartment is installed and
screwed tight before energizing the installation. There are dangerous voltages inside the
cable compartment.
If special configurations or settings are required for the system and they are set via internal
buttons or switches (DIP switch, see chap. 8.1), they should be set before connecting the
PV modules.
The connection of the VarioString must be carried out in the following order. Any disassembly shall
be carried out in the reverse order. Before closing the protections and energizing the equipment,
check the polarity.
A. Connecting the battery: on the BAT+ and BAT- terminals
 Check that the VarioString switches on (green LED "NIGHT" lights up on the
Une étincelle apparait au moment de brancher le deuxième pôle de la batterie. Ceci est
normal.
B. Connecting the photovoltaic panels: on the PV+ and PV- terminals
 Check the PV voltage seen on the RCC. (if present)
 Check the operation of the charger and the effective charging of the batteries when it is
sunny.
Your installation is now in operation. If the system requires specific configurations or settings, carry
them out immediately. Settings must be programmed by means of the remote control RCC-02/03 as
per chap. 8.2 or by means of the internal DIP switches as per chap. 8.1.
If the VarioString has been accidentally connected in reverse (battery reverse polarity on
the panel input), it is likely that the protection device on the battery cables is open. In such
case, recheck carefully the battery polarity, the wiring and the internal fuse of the
VarioString that protects against this situation. If after having closed or replaced the
protection device (f), the VarioString still does not work despite the correct polarity and
voltage of the battery, it must be brought back to the Seller for repair.
