5.2
Normal Mode
When the UPS is in Normal Mode, the Normal Mode Indicator illuminates green.
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 undervolt-
age (boost) or lowers the overvoltage (buck) as needed. The AVR operates automatically and main-
tains 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
5.4
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.
When a Low Battery condition occurs, the Battery Indicator flashes amber and an alarm sounds at
Battery Recharge Operation
Once utility power is restored, the UPS resumes normal operation and the Battery Charger begins
recharging the batteries.

Communication
6.0 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 shutdown software. The connection provides serial communica-
tion, On Battery and Low Battery signals. Liebert MultiLink software and a 6 ft. (1.8m) DB-9 serial
cable are shipped with the UPS.
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 XR 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 operat-
ing. 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 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 shut-
down 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
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.
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 and RS-232 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 operate in parallel. Using the Liebert
IS-WEBRT3 disables the serial communications of the DB-9.
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 volt-
ages 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 bat-
tery mode. The factory default setting is 120 VAC.

Battery Maintenance
7.0 BATTERY MAINTENANCE
7.1
Battery Charging, Storage
The batteries are valve-regulated, nonspillable, lead acid and must be kept charged to retain their
design life. The Liebert PSI XR continuously charges the batteries when connected to the utility sup-
ply, even while the UPS is switched Off.
If the Liebert PSI XR will be stored for an extended period, Liebert recommends connecting the UPS
to input power for at least 8 hours every four to six months to keep the batteries charged.
7.2
Internal Battery Replacement Procedure
NOTICE
This UPS is equipped with internal batteries that the user can replace without shutting down
