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 the “SYSTEM ON” command is activated properly, all measurements will be ok and no anomalies will be
present, open the Manual bypass switch (SWMB).
Verify that the system status changes to “ON LINE” mode.
Now the system is On Line.
NOTE: if the bypass line is represented with a white stripe, it means that the load is supplied by the manual
bypass alone. If the manual bypass switch is opened in this condition, the power to the load will be lost.
The system is off.
Load on static bypass after Manual Bypass
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 system 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”.
