WARNING: the table below frequently recommends the use of the maintenance BYPASS. We remind you that
before restoring the UPS to operation, you must make sure that it is on and not in STAND-BY.
If the UPS is in this latter mode, turn on the UPS by accessing the "SYSTEM ON" menu and wait for the
power-on sequence to be completed before removing the maintenance BYPASS.
For further details read the procedures described in the maintenance BYPASS (SWMB) paragraph.
