Bulk Battery Charging
Selecting
Bulk
allows programming of the max voltage and the float voltage. For more information on bulk battery
charging, refer to the web GUI description "UPS Maintenance > Battery" on page 38.
1. Put the unit in
STANDBY
mode before starting this procedure.
2. Use a combination of the
SCROLL
and
SELECT
keys on the control panel interface to select
CHARGER
in
the Control menu.
3. Select
Bulk
to set the max charge voltage and float voltage for charging the batteries (selectable in 0.1V
increments).
Selecting
Bulk
allows
programming of the max
charge voltage and the
float voltage.
Selectable in 0.1V steps: from 52 to
56V. (Default is 53.5V)
Selectable in 0.1V steps: from 52V
to less than or equal to max charge
voltage. (Default is 53.5V)
NOTE:
Temperature compensation defaults to 0 mv/ °C/ cell in this mode, but can be changed to non-zero values.
If you set the max charging voltage to a value lower than currently set float voltage, float voltage will be
automatically adjusted to be equal to the new max charging voltage.
