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 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.
When a Low Battery condition occurs, the Battery Indicator flashes amber and an alarm sounds at
one-second intervals. Refer to Table 6 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.
Communication
17
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 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 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
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 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.
6.3 Network Surge Protection Connectors
Network (in and out) connectors on the rear of the UPS provide transient voltage surge suppression
(TVSS) for network devices.

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.
6.5 UPS Inverter/Transfer Voltage Configurations
A two-pin DIP switch on the rear of the PSI 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.

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 continuously charges the batteries when connected to the utility supply,
even while the UPS is switched Off.
If the Liebert PSI will be stored for an extended period, Emerson recommends connecting the UPS to
input power for at least 8 hours every four to six months to keep the batteries charged.
Emerson recommends performing a monthly manual self-diagnostic test via the Web card or the front
panel display.
7.2 Internal Battery Replacement Procedure
NOTICE
This UPS is equipped with internal batteries that the user can replace without shutting down
the UPS or connected loads (hot swappable). Caution must be exercised when replacing the
