The following operations are to be performed in order to switch the UPS from “Manual Bypass” to “Load forced on bypass”
status:
Switch on the Mains (SWIN), Bypass (SWBYP) and battery input lines (SWBATT) and close the output switch (SWOUT).
The system will turn on in "STAND-BY WITH CB OFF" mode (The status led will light up and the display will start).
Verify the Mains and Bypass input voltages on the “System measurements” page.
Verify that no anomalies are present on the status bar (except
[C05] “Manual bypass command”).
From the “Command Panel” page, press the “System ON” icon to start the system.
Confirm “System ON Command”, by selecting OK. To ensure that the system is in static bypass mode, verify that the system
is in “MANUAL BYPASS ACTIVE”. In this case the bypass line is represented with a blue strip as in the following image.
From the “Command Panel” page, tap the icon “Bypass command” button to switch the system to static bypass.
Confirm “BYPASS ON Command”.
Verify that the syste
m status changes to “LOAD FORCED ON BYPASS” in a few seconds.
Verify the output voltages on the “System measurements” page and verify that no anomalies are present on the status bar.
Check the status of the batteries (if present) and verify the measurements.
If all measurements are ok, no anomalies are present and the bypass command is activated, open the Manual bypass switch
(SWMB).
Verify that the system status changes to “LOAD FORCED ON BYPASS”.

NOTE: during prolonged periods of inactivity, it is good practice to shut down the UPS; open the input and output
switches (after system off) and lastly, with the UPS off, open the battery fuse holder (SWBATT) to avoid
unnecessary battery discharge.
When the UPS is started again, it is possible that date and time will need to be manually restored.
