REDUNDANT AUXILIARY POWER ADAPTER FOR AUTOMATIC BYPASS
The UPS is equipped with a redundant auxiliary power supply which permits operation on the automatic bypass even in the
event of main auxiliary power faults. In the event of a UPS fault, which also can cause breakage of the main auxiliary power, the
load remains powered by means of the automatic bypass.
If the principal power fails, the redundant power supply will continue to power the logic, display and any comms cards.
CAUTION: In this mode, the backlight and standard RS232 and USB ports will not operate.
The UPS can however communicate via its comms slots.
In this emergency condition, any disturbances present on the input line have repercussions on the load.
POWER WALK-IN
The UPS is equipped with a Power Walk-In mode which can be activated and configured via configuration software. When this
mode is enabled, once the mains power is restored (after a period of autonomy), the UPS begins absorbing from it again
progressively so as not to threaten (due to the peak) for any generator group that may be installed upstream. The duration of
the transition can be set from 0 to 125 seconds. The default value is 10 seconds (when this function is active). During the
transition, the power required is drawn partly from the batteries and partly from the mains while maintaining sinusoidal
absorption. The battery charger is switched back on only after the transition is complete
DERATING OF POWER FOR 220/200/208V PHASE-NEUTRAL LOADS
If the output voltage is set to 220, 200 or 208V PHASE-NEUTRAL, the maximum power that can be supplied by the UPS is
derated relative to its nominal power, as demonstrated in the following graph:
