NSTALLATION

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 100mm (4 inches) on each side of the UPS. Maintain an ambi-
ent temperature range of 0°C to 40°C (32°F to 104°F).

2. Connect equipment to the receptacles on the back of the PSA: computers and monitors should be connected to 

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 black receptacles, which provide surge protection only.

3. Obtain a suitable input power cable with a minimum cross-sectional area of 1mm

to connect the PowerSure 

PSA to the mains supply socket.

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 Mains Indi-

cator will illuminate (green).

6. Turn on connected equipment.

Plug this type of equipment into 

black receptacles ONLY

Plug monitors, computers, & cash registers 

and routers into orange receptacles

OMMUNICATIONS

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.

NDICATORS

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).

TRANSFER VOLTAGE SELECTORS (DIP SWITCHES)

The two-position DIP switch 

control on the rear panel, 

shown at right, allows the 

operator to select the mains 

transfer voltage at which 

the UPS will switch to bat-

tery power. The factory 

default settings are 

100VAC - 135VAC. DIP 

switch positions for each 

voltage setting are:

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 

mains input voltage. DIP switch settings not 

matching the nominal mains could potentially 

damage connected equipment.
