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 an ambient temperature 

range of 0°C to 40°C (32°F to 104°F).

2. Connect equipment to the receptacles on the back of the PST with one of the two supplied 

output cables. Computers and monitors should be connected to the orange receptacles for 
battery backup and surge protection; other office machines that do not exceed the capac-
ity of the UPS may be plugged into either of the two black receptacles, which provide 
surge protection only.

3. Connect an input cable removed from the load equipment to the PowerSure PST and 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 Indicator will illuminate (green).
6. Turn on connected equipment.

Plug this type of equipment

OMMUNICATIONS

The PowerSure PST has a USB interface port 

for communication that will work with the built-

in Microsoft Power Manager software on the 

user’s PC, if the PC is so equipped. It will pro-

vide 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.
