5.0 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 utility power, such
as voltage surges and sags. When the Liebert PSI XR detects an abnormality, it raises the undervolt­age (boost) or lowers the overvoltage (buck) as needed. The AVR operates automatically and main­tains the output voltage to the connected equipment, without utilizing the batteries.

LED 1 flashes green and LED 9 illuminates steady green when the UPS is in Boost Mode. LED 2
flashes green and LED 9 illuminates steady green when the UPS is in Buck Mode (see 9.0 - Trouble-
shooting for details).

5.3 Battery Mode

The UPS switches to Battery Mode in the event of an extreme input voltage/frequency condition or
utility failure.

When the UPS is in Battery Mode, the Battery Indicator illuminates amber and an alarm sounds at
two-second intervals. As capacity decreases, fewer indicators remain illuminated.

Operational Modes

When a Low Battery condition occurs, the Battery Indicator flashes amber and an alarm sounds at
one-second intervals. Refer to Table 8 for approximate battery run times.

5.4 Battery Recharge Operation

Once utility power is restored, the UPS resumes normal operation and the Battery Charger begins
recharging the batteries.

6.0 COMMUNICATION

r

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.

6.2 Remote Shutdown Via the DB-9 Connector

The Liebert PSI XR can be shut down remotely by shorting Pins 5 and 6 or via Pins 4 and 5 of the DB­9 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
in. 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 utility 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 utility power returns.

6.4 UPS Communications

The Liebert PSI XR 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 PSI XR permits setting the UPS to operate at nominal volt­ages of 110V, 120V or 127V. This feature will change the high and low points at which the UPS
switches to battery power. It also changes the UPS’ output voltage when the UPS is operating in bat­tery mode. The factory default setting is 120 VAC.

Turn Off the UPS before making any changes to the voltage configuration.
