OPERATIONAL MODES
5.1
Normal Mode
When the UPS is in Normal Mode, the Normal Mode Indicator illuminates green.
5.2
Buck/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.
5.3
Battery 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.
5.4
Battery Recharge Operation
Once mains power is restored, the UPS resumes normal operation, and the Battery Charger begins
recharging the batteries.

COMMUNICATION
6.1
DB-9 Connector
The UPS has a DB-9 (9 pin female) connector on the rear to allow UPS status communications with a
computer running Liebert MultiLink software in contact closure mode. The connection provides On
Battery and Low Battery notification.
When power is interrupted and battery power is low, Liebert MultiLink software can signal the host
computer to gracefully shut down the operating system.

Remote Shutdown Via the DB-9 Connector
The Liebert PSI can be shut down remotely by shorting Pins 5 and 6 or via Pins 4 and 5 of the DB-9
connector.
6.2.1
Any Mode Shutdown Via Pins 5 & 6
When Pin 6 is shorted to Pin 5, the UPS output is shut Off no matter what mode the UPS is operating. The UPS cannot be started as long as the pins are shorted. When the short is removed, the UPS
output can be enabled by pressing the ON/Alarm Silence/Manual Self-Diagnostic Test button.
6.2.2
Battery Mode Shutdown Via Pins 4 & 5
While the UPS is operating on battery, a 5-12VDC signal for 2 seconds or longer is required to signal
a shutdown. Signals for less than 2 seconds are ignored.
After Pin 4 receives the shutdown signal, a 2-minute shutdown timer begins a countdown. The shutdown timer cannot be stopped: If mains power returns during the 2-minute countdown, the shutdown
timer continues until the end of 2 minutes and the UPS turns Off. The UPS will restart 10 seconds
after mains power returns.
6.3
RJ-45 Data Line Protection Connectors
Data line (in and out) connectors on the rear of the UPS provide transient voltage surge suppression
(TVSS) for network devices.
16
Communication
6.4
UPS Communications
The Liebert PSI is equipped with a Liebert IntelliSlot port to provide advanced communication and
monitoring options.
Liebert MultiLink software continually monitors the UPS and can shut down your computer or server
via USB, contact closure and SNMP (via IS-WEBRT3 card) in the event of an extended power failure.
The Liebert IS-WEBRT3 provides SNMP and Web-based monitoring and control of the UPS across
the network.
NOTE
The USB, SNMP and contact closure communications can operate in parallel.
6.5
UPS Inverter/Transfer Voltage Configurations
A two-pin DIP switch on the rear of the Liebert PSI permits setting the UPS to operate at nominal
voltages of 220V, 230V or 240V. This feature will change the high and low points at which the UPS
switches to battery power. It also will change the UPS’ output voltage when the UPS is operating in
battery mode. The factory default setting is 230 VAC.
Turn Off the UPS before making these changes to the voltage configuration.
