CENTRIC 3x480, User Guide, rel. 1.7
7.2.4
Setup > BATTERY
The Setup > BATTERY functions provide control over a number of battery parameters.
The Centric supports the use of standard lead-acid batteries, and also lithium-ion batteries. If you plan to
use lithium-ion batteries, consult with your dealer to be sure that the battery setup parameter values are
appropriate for the batteries you will be using.

7.2.4.1
SETUP > BATTERY > BATTERY TEST PARAMETERS
The parameters in this section relate to the battery test function.
7.2.4.1.1
B
ATTERY TEST FAULT VOLTAGE
When this voltage is reached during a battery test, the battery has failed the test.
7.2.4.1.2
R
ECTIFIER VOLTAGE DURING BATTERY TEST
Sets the value to which the rectifier's output voltage descends during a battery test.
7.2.4.1.3
A
UTOMATIC BATTERY TEST INTERVAL
The UPS conducts a periodic battery test automatically according to the time interval specified here. The
time interval is specified in weeks.
7.2.4.1.3.1 Factors delaying the automatic battery test
•
In the event that the UPS’s ac input voltage is high, the battery test is postponed until the UPS’s input
voltage becomes lower. A “high” input voltage in this case means “greater than the battery test voltage
divided by
√2
”. The battery test voltage is that defined above in section
voltage”.
If the ac input voltage rises above this threshold during the battery test, the test is aborted and
rescheduled to take place in 24 hours.
