5.0OPERATIONAL MODES
5.1Normal Mode
When the UPS is in Normal Mode, the Normal Mode Indicator illuminates green.
5.2Buck/Boost Mode
The Automatic Voltage Regulator (AVR) circuitry compensates for fluctuations in mains power, such
as voltage surges and sags. The Liebert PSI compensates for these by raising the undervoltage (boost)
or lowering the overvoltage (buck). The AVR operates automatically and maintains the output voltage
to the connected equipment without utilizing the batteries.
5.3Battery Mode
The UPS switches to Battery Mode in the event of an extreme input voltage/frequency condition or
mains failure.
When the UPS is in Battery Mode, the Battery Indicator illuminates amber and an alarm sounds at
2-second intervals. As capacity decreases, fewer indicators remain illuminated.
When a Low Battery condition occurs, the Battery Indicator flashes amber and an alarm sounds at
one-second intervals. For approximate battery run times, refer to Table 6.
Operational Modes
5.4Battery Recharge Operation
Once mains power is restored, the UPS resumes normal operation, and the Battery Charger begins
recharging the batteries.
