INSTALLATION
Read all safety, installation and operating instructions in the PowerSure family user manual on the included CD or
at www.liebert.com before operating the UPS. Adhere to all warnings on the unit and in the manual.
1. Install the UPS indoors in a controlled environment, where it cannot be accidentally turned off. Place it in an area
of unrestricted airflow around the unit, away from water, flammable liquids, gases, corrosives and conductive
contaminants. Maintain a minimum clearance of 4 inches (100mm) on each side of the UPS. Maintain an ambi-
ent temperature range of 32°F to 104°F (0°C to 40°C).
2. Plug the PSA’s power cord into an AC outlet. Check the Site Wiring Fault Indicator on the rear; if it is illuminated,
refer to the Troubleshooting section.
3. Plug any computers and monitors into the orange receptacles for battery backup and surge protection; other
office machines that do not exceed the capacity of the UPS may be plugged into either of the two (2) black
receptacles, which provide surge protection only.
4. Connect Phone/Fax/DSL/Internet/Modem devices to data line connectors.
5. Press and release the ON/OFF/Alarm Silence button to turn on the UPS. The UPS will beep and the Utility Indi-
cator will illuminate (green).
6. Turn on connected equipment.

COMMUNICATIONS
The PowerSure PSA will communicate with your computer in either of two ways: over its DB-9 port through Lie-
bert’s MultiLink
™
software or by USB through Microsoft
®
Windows
®
operating system features.
MultiLink supplies useful monitoring data, such as input voltage and battery level, and will perform an orderly shut-
down of the computer system. Microsoft Windows XP and 2000 operating system utilities supply UPS status infor-
mation and will perform an orderly computer shutdown. Check your computer’s OS features to determine whether
it has power management capability.
For MultiLink Serial Communications
• Connect the provided MultiLink serial cable to the DB-9 ports on the rear of the UPS and on the rear of your
computer.
• Install the MultiLink software—the software, installation instructions and the user manual are on the CD included
in the PowerSure PSA package.
For USB Communications (with operating system power management)
• Connect the USB cable provided with the UPS to the USB ports on the PSA and your computer. The PSA will
work automatically with the built-in power management software on Windows XP and 2000 or later.
• All USB models are compatible with Microsoft Windows 2000, Windows XP and Macintosh
®
OS 10.2 or later.
CONTROLS AND INDICATORS
This button controls output power to the connected
load and has three functions:
• Turns the PowerSure PSA ON
• Turns the PowerSure PSA OFF
• Silences PowerSure PSA alarms
TURN THE UPS ON: Press and release the main ON/OFF
button to start the UPS. An audible alarm will sound briefly.
TURN THE UPS OFF: When the PSA is ON, hold the main
ON/OFF button down for more than 2 seconds to shut it down.
An audible alarm will sound briefly.
SILENCE AN ALARM: When a UPS alarm is active, press and
release the main ON/OFF button to silence the audible alarm
(Exceptions: low battery, overload and overtemperature). DO
NOT hold the button down for more than 2 seconds or the PSA
will shut down.
CHECK THE PSA’S CONDITION: Three status indicators on
the front of the UPS illuminate to specify the status of the UPS
(see Troubleshooting section for details).
SITE WIRING FAULT INDICATOR (RED)
The Site Wiring Fault Indi-
cator on the rear panel, as
shown, illuminates red
when the UPS detects a
line-neutral reversal or a
poor neutral-ground. (See
Troubleshooting Chart if
indicator is illuminated.)
TRANSFER VOLTAGE SELECTORS (DIP SWITCHES)
The two-position DIP switch control on the rear panel, shown
above, allows the operator to select the utility transfer voltage
at which the UPS will switch to battery power. The factory
default settings are 100VAC - 135VAC. DIP switch positions for
each voltage setting are:
DIP switch settings
Left Right Nominal Utility Setting
↑ Up ↑ Up 120VAC 85 - 145VAC (default)
↑ 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.
