Otherwise (the final status "UPS Running" is not reached),
or if the process is interrupted, check the Alarms menu, and
inform the qualified Technical Service if necessary.
11.
Set the switch corresponding to the UPS output on
the control panel (external) to "On".
12.
Set the output switch of the UPS to "On" (
Q2
).
The unit
supplies voltage at the output terminals of the control
panel.
13.
Start the loads (or set their switches on the distribu-
tion board to "On", if any) progressively.
14.
The system is operating fully, and the loads are pro-
tected by the UPS
. You can obtain basic information on
the main screen of the control panel (synoptic, input and
output voltages, system load percentages).

Main screen in normal operation. The power flow
should match the one shown: input supplies rectifier;
this simultaneously supplies the inverter and the
battery charger; the inverter supplies power to the
output loads.
6.1.4. Procedure for transferring to bypass mode
On specific occasions, for example temporarily while awaiting
an intervention on the UPS due to a fault, or as indicated by the
Service Technician, it may be useful to manually transfer the
UPS to bypass mode (see
).
In this operating mode, the loads will not be protected
against power outages and line disturbances.
With the UPS operating in normal mode (synoptic shown in
, and in the "Status and Control" submenu you can see that
the "UPS Status" shows "UPS Running"), in order to switch to
bypass mode, proceed as follows:
1.
Press the "Status and Control" icon
You are
.
2.
Press the "INV/BYP Output" icon
3.
The "UPS Control" pop-up box appears, with the "In-
verter" and "Bypass" options. Press “Bypass”.

"Output Control" pop-up window. Press "Bypass".
4.
The loads switch to being supplied directly from
the static bypass line
. The unit's inverter is shutdown
(waiting), but the rectifier and charger are operating (the
battery charge is maintained). A new "UPS Unit on Bypass"
alarm appears, warning us of the current "risk" situation for
critical loads.

Main screen in bypass mode. The power flow
goes directly from the bypass input to the output,
via the static bypass switch. The rectifier and
charger continue operating.
The unit is now in bypass operating mode, described in
.
6.1.5. Procedure for transferring to normal mode from
bypass mode
Based on the situation described in
(manual forced bypass
mode), you can recover the normal operating mode of the UPS
via manual command.
By accessing the "Status and Control", you can see that the
"UPS Status" shows "Rectif. Running". To switch to bypass
mode, you need to:
1.
Press the "Status and Control" icon
You are
.
2.
Press the "INV/BYP Output" icon
3.
The "Output Control" pop-up box appears, with the "In-
verter" and "Bypass" options. Press "Inverter".
