When the UPS is first started up, it is in on-line mode (see page 28 ). See “Display and control panel”
manual, to set Standby-on / Smart active operating mode.
configurations
Contact the technical support personnel for other operating modes.
Once the UPS has been installed, check that the message NORMAL OPERATION appears on the first line of the
display panel and that the UPS model is displayed in the left-hand corner of the second line according to the coding
shown below:
X000YZZ
X LIBRAPRO model
000 output power [kVA]
Y output frequency:
Y = _
output 50Hz
Y = A
output 60Hz
Z configuration mode:
Z = __
output frequency = input frequency
Z = _ C
frequency converter with battery
Z = KS
frequency converter without battery
Z = N
standby on
Z = F
stand by off
Z = S
stabilizer
Z= P or p parallel version
Z= B or b parallel version with single battery
3.5.1 Battery operation check
Carry out only with battery present.
After installation, a mains outage even of just a few seconds can be simulated to check operation (the battery
does not need to be charged).
With the UPS in normal operation, open switch SWIN located at the UPS input (rectifier). The buzzer should
sound immediately (with 5=ON) while OUT. (green LED) and BATT. (yellow LED) on the Signals and
Commands Panel should be constantly on.
Check that the load connected to the UPS is powered. In this state, the power supplied to the load is the same as
the energy that was previously accumulated in the batteries. Close input disconnector SWIN to return to normal
operation. The IN. and OUT. LEDs on the CONTROL PANEL will be GREEN.
The batteries will recharge automatically.
Battery backup time
Before a battery discharge test can be carried out, several hours have to pass (at least eight hours for
standard backup times or longer for batteries sized for long backup times) to allow the batteries to
charge.
The backup time obtained on the first discharge may be slightly less than expected; a number of charge
and discharge cycles are needed to improve this value.
Battery capacity does not remain constant over time, but increases after some charge and discharge
cycles; it then remains constant for several hundreds of cycles before decreasing permanently.
