ONNECTING THE BATTERY
Lead batteries are usually available in 2 V, 6 V or 12 V block types. In the majority of cases, in order
to obtain an operating voltage that is correct for Xtender usage, several batteries must be
connected in series or in parallel depending on the circumstances.
The various cabling options are presented in figures 5a-5b (12 V), 5c-5e (24 V) and 6a to 6d (48 V) in
appendix I of this manual.
4.5.1
Battery cable cross-section and DC protective devices
The battery cables must also be as short as possible.
It is always preferable to keep the cable at the negative pole of the battery as short as possible.
In order to avoid any further loss and protection redundancy, the XTH does not have an internal
fuse.
A protective device (f) must be installed as close as possible to the battery and sized according to
the below table.
The recommended cable cross-sections are valid
for lengths less than 3 m. beyond this length it is
strongly recommended oversize the battery
cables.
The diagrams shown in the appendix of this document are subsidiary. The applicable
local installation regulations and standards must be adhered to.
The elements referred to with an uppercase letter denote the alternate current (AC)
part.
The elements referred to with a lowercase letter denote the direct current (DC) part.
In multi-unit systems, all Xtenders from the same system must be connected according to
the same battery bank.
The battery cables must be protected by one of the following measures in all cases:
- protection device (fuse) at each pole
- protection device (fuse) on the pole not connected to the earth
Range Battery side fuse
