2.0 INTRODUCTION
Congratulations on your choice of the Liebert PowerSure™ PSI Uninterruptible Power Supply (UPS).
It provides conditioned power to microcomputers and other sensitive electronic equipment.
Upon generation, AC power is clean and stable. However, during transmission it may be subject to
voltage sags, spikes, or complete power failure which may interrupt computer operations, cause data
loss, or even damage equipment. The PowerSure PSI protects equipment from these disturbances.
The PowerSure PSI comes in nominal power ratings of 1000, 1440, 1920, 2200 and 3000 VA. Refer to
the Specifications section for details.
The PowerSure PSI is a 2U, line-interactive UPS that may be installed in a rack or used in a tower
configuration. A line-interactive UPS continuously conditions and regulates its output voltage,
whether utility power is present or not. It supplies connected equipment with clean, sinewave power
to simulate the power generated by the utility. Sensitive electronic equipment operates best from
sinewave power.
For ease of use, the PowerSure PSI contains Status Indicators to display Load Level, Battery Level,
Buck/Boost, Over Temperature and Battery. It also provides self-diagnostic tests, a combination ON/
Alarm Silence/Battery Test button, an OFF button and Voltage Programming button.
The PowerSure PSI has USB, DB-9 (RS232/contact closure) and Intellislot interface ports for communications between the UPS and a LAN server or other computer systems. The DB-9 port provides
detailed operating information including voltages, currents, and alarm status to the host system
when used in conjunction with Liebert’s MultiLink™ software. MultiLink software can also remotely
control UPS operation. The USB port provides detailed operating information and alarm status to the
host system when used in conjunction with the Liebert Human Interface Device (HID) and Microsoft
Power Manager software.

3.1 Transient Voltage Surge Suppression (TVSS) and EMI/RFI Filters
These UPS components provide surge protection and filter both electromagnetic interference (EMI)
and radio frequency interference (RFI). They minimize surges or interference present in the utility
line and keep the sensitive equipment protected.
3.2 Relay
In Normal mode the Relay passes utility AC power to the connected load. When input utility voltage
or frequency is outside acceptable limits, the Relay activates and transfers the UPS to battery.

Page 13
3.3 Automatic Voltage Regulator
The Automatic Voltage Regulator (AVR) protects connected equipment from power spikes, sags and
other abnormalities by raising (boosting) or lowering (bucking) the output voltage as needed. This
keeps the UPS output voltage within the connected equipment’s tolerance and accommodates wide
utility voltage fluctuations without utilizing the batteries.
3.4 Battery Charger
In Normal mode, the Battery Charger converts utility AC power into regulated DC power to float
charge the battery. It is continuously charging the battery whenever the UPS is plugged into a power
outlet and utility power is within acceptable limits - even if the UPS is turned Off.
3.5 Battery
The PowerSure PSI utilizes valve-regulated, nonspillable, lead acid batteries. To maintain battery
design life, operate the UPS in an ambient temperature of 68°F to 77°F (20°C to 25°C). Optional
external battery cabinets are available to extend battery run times.
3.6 Inverter—1000/1440 Models Only
In battery mode operation, the inverter utilizes the DC output of the battery and inverts it into precise, regulated, sinewave AC power.
Major Components
3.7 DC-to-DC Converter—1920/2200/3000 Models Only
The DC-to-DC Converter utilizes energy from the battery system and raises the DC voltage to the
optimum operating voltage for the Bi-Directional Converter. This allows the Bi-Directional Converter
to operate continuously at its optimum efficiency and voltage, thus increasing reliability.
3.8 Bi-Directional Converter—1920/2200/3000 Models Only
In normal operation, the Bi-Directional Converter changes utility AC power into regulated DC power
to “float charge” the battery system. This converter is continuously charging the battery whenever the
UPS is plugged into a power outlet and utility power is within acceptable limits—even if the UPS is
turned Off. When utility power fails, the Bi-Directional Converter draws energy from the battery
through the DC-to-DC Converter and inverts it into a regulated sinewave supplying power to connected equipment.

7.0 MODES OF OPERATION
7.1 Normal Mode
During Normal mode operation, the PowerSure PSI supplies conditioned, computer-grade power to
the connected equipment: utility power passes through the TVSS circuitry and the EMI/RFI filters
and then through the Inverter (1000VA & 1440VA) / Bi-Directional Converter (1920VA, 2200VA and
3000VA) to connected equipment.
When the UPS is in Normal mode, the AC Input Indicator illuminates green. The UPS display in
Figure 14 shows the UPS operating in Normal mode with 26% - 50% load connected to the output.
Figure 14 Normal mode operation with 26-50% load
Utility power present ...
... and within operational limits
Modes of Operation
The PowerSure PSI continuously monitors the batteries to maintain them in a fully charged state.
The battery charger operates whenever AC power is present, even if the UPS is switched Off. By
default, the UPS is set to perform an automatic battery test after it has been operating continuously
for two (2) weeks. The automatic battery test can be disabled via MultiLink.
7.2 Buck/Boost Mode
The Automatic Voltage Regulator (AVR) circuitry compensates for fluctuations in utility power, such
as voltage surges and sags. When the PowerSure 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 critical equipment, without utilizing the batteries.
The Buck/Boost Indicator flashes green when the UPS is operating in Buck mode and illuminates
green when the UPS is operating in Boost mode (see Troubleshooting section for details).
Figure 15 Buck/Boost mode operation with 51-75% load and 21-40% battery capacity
Indicator shows
UPS in Boost Mode
(solid green)
17
Page 24
7.3 Battery Mode
The UPS switches to Battery mode in the event of an extreme input voltage/frequency condition or
complete utility failure. The battery system supplies power through the Inverter (1000VA & 1440VA)
or through the DC-to-DC converter to the Bi-Directional Converter (1920, 2200VA and 3000VA) to
generate power for the connected equipment.
When the UPS is in Battery mode, the Battery Indicator illuminates green and an alarm sounds
every 10 seconds. As capacity decreases, fewer indicators remain illuminated. Figure 16 shows the
UPS in Battery mode with 61% - 80% battery capacity remaining.
Figure 16 Battery mode at 61 – 80% battery capacity
When a low battery condition occurs, the Battery Indicator flashes green and the alarm sounds every
half-second. The default low battery warning is two (2) minutes but can be configured via MultiLink.
For more information, refer to Troubleshooting section.
Modes of Operation

8.0 COMMUNICATIONS
r
8.1 DB-9 Connector
The UPS has a DB-9 (9 pin female) connector on the rear to allow UPS status communications with a
computer system running MultiLink software. The DB-9 is capable of supplying serial communication, on battery and low battery signals. MultiLink, Liebert’s UPS monitoring and shutdown software, is shipped with the UPS, along with a 10 ft. (3m) DB-9 cable required for running MultiLink.
When MultiLink is installed on the host computer, the UPS can signal “on battery” and “low battery”
using opto-couplers. When the UPS is operating in Battery mode, it can receive a signal from the host
computer system that will shut down the UPS (after gracefully shutting down the operating system
on the host computer system) when the remaining battery run time is low. The timing of the signal
depends on MultiLink’s configuration settings. This shutdown signal (5-12VDC) must have a duration of at least 2 seconds for the UPS to be shut down. The UPS communicates via serial communications using Liebert ESP II protocol.

8.2 Remote Shutdown Via the DB-9 Connector
The PowerSure PSI can be shut down remotely by shorting Pins 5 and 6 or via Pins 4 and 5 of the
DB-9 connector.
8.2.1 Any Mode Shutdown—Via Pins 5 & 6
When Pin 6 is shorted to Pin 5, the UPS output is shut Off regardless of 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/Battery Test button.
8.2.2 Battery Mode Shutdown—Via Pins 4 & 5
While the UPS is operating on battery (with no battery test in progress), 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 inside the UPS begins a countdown. The timer cannot be stopped. If utility power returns during the 2-minute timer countdown,
the shutdown timer continues until the end of 2 minutes and then the UPS turns Off. By default,
autorestart is enabled so the UPS will restart after 10 seconds. If autorestart is disabled via MultiLink software, the UPS remains Off until a manual restart.

electrician.
Wait until voltage lowers to an appropriate level
or have the utility power checked by a qualified
electrician.
Check load level display and remove nonessential loads. Recalculate the load and reduce
number of loads connected to UPS - the total
wattage of your equipment must not exceed the
capacity of the UPS.
Make sure that the UPS is operating in 32°F to
104°F (0°C to 40°C) and that it has adequate
ventilation.
Consult the MultiLink user manual or contact your
LAN administrator.
Contact your local dealer, Liebert representative
or the Liebert Worldwide Support Group.
Your UPS has received a signal or command
from the attached computer. If this was
inadvertent, ensure the communication cable
used is correct for your system. For assistance,
contact your local dealer, Liebert representative
or the Liebert Worldwide Support Group.
Have the utility checked by a qualified electrician.
Check battery connections,
completely power down and restart UPS.
NOTE: If the battery circuit opens while the UPS
is running, it will be detected when the next
battery test is performed.
Make sure that the UPS is operating in 32°F to
104°F (0°C to 40°C) and that it has adequate
ventilation.
Reset UPS.
NOTE
The 1920VA UPS will sound an Overload alarm under certain Low Line conditions when it is
fully loaded and it exceeds the input current rating. Unless the load is reduced, the condition
will trip the branch circuit breaker.
