4.2.2 Connecting the battery
All connection cables as well as the battery cables must be mounted using cable restraints in order
to avoid any pulling on the connection.
Battery cables must be as short as possible and the cross-section must comply with the regulations
and standards in force. Tighten the clamps on the “Battery” inputs sufficiently.
Lead batteries are usually available in 2V, 6V or 12V blocks. In most cases, in order to get the correct
operating voltage for the VarioString, several batteries must be connected in series. The capacity of
the batteries can be increased using a parallel connection of several battery strings.
Some battery manufacturers limit the use or advice against parallel connection of battery strings.
Strictly conform to the manufacturer's instructions of use.

4.2.3 Protection device of the battery
The battery cables must be as short as possible. The recommended cable cross-section is 25mm2 for
VS-70 and 50mm2 for VS-120. The protection devices (battery side) must be 80A for VS-70 and 125A
for VS-120. The protection device must be installed as close as possible to the battery. The
recommended cross-section of battery cable is valid for lengths up to 3m. Beyond this length, it is
recommended to oversize the section of the battery cables.
Any other sources or loads existing on the battery must be connected using their own protection
devices. Never connect them to the protection device(s) of the VarioString.
A battery voltage higher than 75V can cause important damage or destroy the equipment.
Such a voltage applied on equipment connected downstream like Xtender
inverters/chargers or other, can cause important damage or destroy the equipment!
Each VarioString is connected directly to the battery using its own protective device. All other
consumers or sources are connected directly to the battery through their own protective device.
In multi-unit systems (connected to the same communication bus), all VarioStrings must be
connected to the same battery bank.
An annual check of all the connection tightness is recommended. In mobile installations,
the connection tightness should be checked more often.
Battery cables must always be protected by a protection and disconnection device (fuse,
circuit breaker) on the pole not connected to earth.
The protection device must be rated according to the cable cross-section but must not exceed
1.25 x VarioString maximum current. It will be mounted as close as possible to the battery.
