Transient Voltage Surge Suppression (TVSS) & EMI/RFI
Filters

These UPS components provide surge protection and filter electro­magnetic interference (EMI) and radio frequency interference (RFI).
They minimize surges or interference present in the utility line and
keep the sensitive equipment protected.

Automatic Voltage Regulator

The Automatic Voltage Regulator (AVR) protects connected equip­ment from power spikes and other abnormalities by raising an under­voltage (boost) and lowering an overvoltage (buck) as needed. This
keeps the UPS output voltage within the connected equipment’s toler­ance and accommodates wide utility voltage fluctuations without uti­lizing the batteries.

Bi-Directional Converter

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 and inverts it into a regulated stepped sinewave sup­plying power for equipment connected to the orange receptacles.

Battery

The PowerSure PSA utilizes valve-regulated, nonspillable, lead acid
batteries. To optimize battery life, operate the UPS in an ambient
temperature of 68°-77°F (20° -25°C).

↑ Up ↓ Down 110VAC 78 - 138VAC
↓ Down ↑ Up 127VAC 90 - 150VAC
↓ Down ↓ Down 120VAC 85 - 145VAC

CAUTION

!

Never change the voltage settings while the UPS is ON and
powering connected loads. Change DIP switches only when
the UPS is OFF.

CAUTION

!

To ensure protection of the connected equipment, the DIP
switch settings should match the nominal utility input
voltage. DIP switch settings not matching the nominal
utility could potentially damage connected equipment.

13

MODES OF OPERATION

Normal Mode

During Normal mode operation, the PowerSure PSA 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 Bi-Directional Converter to connected equipment.

When the UPS is in Normal mode, the Utility Indicator illuminates
green.

Utility Indicator (Green)

The PowerSure PSA 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 interval at which the UPS
will perform a battery test can be configured via MultiLink.

Buck/Boost Mode

The Automatic Voltage Regulator (AVR) circuitry compensates for
fluctuations in utility power, such as voltage surges and sags. When
the PowerSure PSA 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.

When the UPS is in Buck /Boost mode, the Utility Indicator illumi­nates amber.

Utility Indicator (Amber)

14

Battery Mode

The UPS switches to Battery mode in the event of an extreme voltage/
frequency condition or complete utility failure. The battery system
supplies power through the Bi-Directional Converter to generate
power for connected equipment.

When the UPS is in Battery mode, the Battery Indicator illuminates
green and an alarm sounds every 10 seconds.

Battery Indicator (Green)

When a low battery condition occurs, the Battery Indicator changes to
flashing amber and the alarm sounds every half-second. Low battery
warning is defaulted to two (2) minutes but can be configured via Mul­tiLink. For more information, refer to Troubleshooting section.

Battery Indicator (flashing Amber)

CAUTION

!

Turning off the UPS while in either Normal mode or Battery
mode will result in the loss of output power.

NOTE

Once utility power is restored, the UPS resumes normal
operation. At this time, the battery charger begins recharging
the battery. The UPS is capable of OFF-State charging, i.e.,
with utility power, the UPS will charge the batteries as long
as it is plugged in.

15

COMMUNICATIONS

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.

Remote Shutdown Via the DB-9 Connector

The PowerSure PSA can be shut down remotely by shorting Pins 5
and 6 or via Pins 4 and 5 of the DB-9 connector.

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/ OFF /Alarm Silence button.

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.

USB Interface Port

The PowerSure PSA has a USB interface port for communication that
will work with built-in Microsoft Power Manger software on the user’s
PC, if so equipped. It will provide UPS status and manages the auto­matic orderly shutdown of the computer. The UPS (USB) communica­tions meets HID standard, version 1.11. All USB models are compatible
with Microsoft Windows 2000, Windows XP and Mac OS 10.2 or later.
All USB models ship with a 6 ft. (1.8m) USB cable.

Microsoft, Windows, and the Windows logo
are trademarks, or registered trademarks of
Microsoft Corporation in the United States
and/or other countries.

Data Line Protection Connectors

Data line (IN & OUT) connectors are located on the rear of the UPS
and provide transient voltage surge suppression (TVSS) for Phone/
Fax/DSL/Internet/Modem devices.

17

MAINTENANCE

The PowerSure PSA UPS requires very little maintenance. Follow
these practices to prevent problems.

Cleaning the UPS

The following will help ensure trouble-free operation for years:

• Vacuum dust from the ventilation intake occasionally.

• Wipe the cover periodically with a dry cloth.

Maintaining Batteries

The batteries are valve-regulated, nonspillable, lead acid and must be
kept charged to retain their design life. The UPS continuously charges
the batteries when connected to the utility supply, even while the UPS
is switched off.

When storing the UPS, it is recommended to plug in the UPS for at
least 24 hours every four to six months to ensure full recharge of the
batteries.

Battery Replacement

CAUTION

!

A battery can present a risk of electrical shock and high
short circuit current. The following precautions should be
observed before replacing the batteries:

• Remove rings, watches, and other metal objects.

• Do not lay tools or other metal objects on top of the bat­teries.

• If the battery replacement kit is damaged in any way or
shows signs of leakage, contact your local dealer or Lie­bert representative immediately.

• Do not dispose of batteries in a fire. The batteries may
explode.

• Dispose of old batteries according to local codes.

This UPS is equipped with internal “hot swappable” batteries that the
