The following operations have to be performed in order to switch the UPS f
rom “Manual Bypass” to ON LINE mode:
Switch on the Mains (SWIN), the 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 that the Mains and the Bypass input voltages are present 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 the “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 filled line as indicated in the
following image.
✔
✘
The bypass line is represented with a filled blue line. In this
condition, it is possible to open the manual bypass switch.
The bypass line is represented with a white stripe. In this
condition, do not open the manual bypass switch: the load
will be lost.
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.
