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 4 inches (100mm) on each side of the UPS. Maintain an
ambient temperature range of 32°F to 104°F (0°C to 40°C).
2. Plug the PST’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 Indicator will illuminate (green).
