3.5 Start-up procedure
The operations described in this chapter must be carried out exclusively by a specialized technician .
mains power supply
The mains power supply has to be present in order to start up the LIBRAPRO
The LIBRAPRO output terminals will be powered in this phase and all applications connected will receive
voltages. All users must therefore be warned before carrying out the start-up procedure.
BATTERY CABINET if present:
The battery cabinet
must be provided with fuses device for it to be connected to the UPS.
Once the INPUT/OUTPUT and battery cables have been connected to the UPS terminals and before putting the
switch cover back in place, check that:

all the input/output terminals are securely tightened;

all the fuseholders have the fuse inserted, and are in the closed position;

the input and output protection conductor is connected correctly (yellow/green earth cable);

check the polarity of the battery connections.
Replace the switch cover.
For the first start-up, the following operations should be carried out in this order:
1) close input disconnector SWIN,
2) press button 1 twice, select the language and then press button 8 to return to the basic menu,
3) close by-pass line disconnector SWBY,
4) close output disconnector SWOUT.
5) close the battery cabinet disconnector
Configure the value of the battery capacity according to the instructions on “Display and control panel”
manual.
battery capacity
It is important to insert the correct battery capacity value, since this value is used by the system logic to
calculate the backup time.
If not set otherwise, this value is assumed to be equal to the UPS power. e.g. at 100kVA the value set by
default is 100Ah .
After the start-up operations have been completed, perform a manual battery test:
press button 3 and then 2 on the control panel. At the end of the test, after approx. 8 seconds, with the UPS
started correctly and with the battery connected on the signals and control panel, the two green input and
output LEDs must be on constant.
SWMB
The disconnector SWMB must not be closed during normal operation of the LIBRAPRO.
SWMB should only be closed during UPS maintenance operations in order to keep the load powered (see
the instructions on page 30).
