9.15. Input voltage high/Input voltage low Alarms
If the input voltage is not within the specified limits, these alarms appear. In this case, UPS operates
in Battery Operation mode, as soon as the mains returns to specified limits, then the alarm shall
dissappear.
If the mains does not return to normal conditions during Battery Operation, UPS will
be
turned off and all loads at the output would be deenergized at the end of battery
autonomy.
9.16. Bypass voltage high/ Bypass voltage low Alarms
If the bypass voltage is not within the specified limits, these alarms appear. In this case, UPS operates
in Online Operation mode, as soon as the mains returns to specified limits, the alarm shall dissappear,
but never switches to Bypass Operation. If UPS needs to be switched to bypass at this moment, UPS
will cut the output and load would be deenergized.
