DC-UPS Configuration
Before powering on, the DC-UPS must
be configured via the selectors and
dipswitches on the front panel.
6.1
Output Voltage Setting
This is a
Selectable Output Voltage
DC-UPS
device, 12 Vdc or 24 Vdc.
Before powering on the device, it is
fundamental to select the correct output
voltage to match load and battery rated
voltage.
WARNING
Special care must be paid
when setting this
parameter since a wrong
configuration may cause
damages to load and
battery.
Do not change dip switch 1
position while the device is
energized. It might cause
damages to load and
battery. If in need to do so,
power off the device first.
Factory setting is always 12 Vdc, the
lowest of the two featured voltages. This
corresponds to top dip switch n. 1 in
position A.
Figure 6.1 -Setting Output Voltage
In case 24 Vdc is required, before
powering on the device, move dip switch
n. 1 to position B.
6.2
Maximum Charge
Current Setting ( 7 )
It is a key setting in enabling a safe and
extended battery lifetime. Adjustment of
the maximum Charge Current selector
allows to protect the battery from
excessive charging currents.
To determine this value, refer to the
battery manufacturer’s datasheet. If this
is not available, consider a maximum
charge current in the range between 1/10
and 1/8 of battery rated capacity given in
Ah. (Example: for a 10 Ah battery = 1.0 – 1.3
A). This approximate value is suitable for
Lead Acid and NiCd but not necessarily
for other types of batteries.
Figure 6.2 – Maximum Charge Current Setting
To select the desired maximum charge
current, rotate the corresponding
selector (7). Current can be set between
10-100% of DC-UPS nominal current.
Factory setting is 10%.
Battery charging current is
capped by the maximum
charging current set on the
selector (7).
6.3
Battery Type Setting
This device allows different battery
charging operations based on the
installed battery type. To select the
correct type, the 3
rd
, 4
th
and 4
th
dip switch
must be configured according to the
following table.
WARNING
Switch off the system before
selecting battery type on the
Dip Switch.
