Connecting external batteries
Make sure there is a battery circuit breaker between the UPS and the battery module.
Before connecting the battery module and the UPS, the circuit breaker must be turned
OFF.
Make sure the number of batteries in the battery module is appropriate for the amount
for which the UPS has been configured. The standard quantity of 12 V batteries for the
UPS is 20.
Connect one end of the battery cable to the appropriate socket on the rear panel of the UPS, the other
end to the socket located on the battery module. In the case of more battery modules, the remaining
connections are made between the supplied battery modules as in the figure below.
If it is necessary to extend the autonomy time, the power supply has the option of connecting a battery
with a much larger capacity, thanks to the fact that it is equipped with an adjustable Charger with a
capacity of 4A. Changes to the settings of the maximum battery charging current are made by an
authorized service of the PSU manufacturer.
When using larger capacity external batteries, placed on racks or in cabinets, special
attention should be paid to the installation of an additional disconnector in the battery
circuit, the correct polarity of the cables connected to the UPS battery and the number of
batteries used.
Incorrect connection of the "+" and "-" wires or connection of the wrong number of
batteries may cause permanent damage to the UPS and the batteries.
