Transient Voltage Surge Suppression (TVSS) & EMI / RFI
Filters
These UPS components provide surge protection and filter electro-
magnetic interference (EMI) and radio frequency interference (RFI).
They minimize surges or interference present in the mains line and
keep the sensitive equipment protected.
Transfer Switch
In Normal mode the Transfer Switch passes mains AC power to the
connected load. When input mains voltage or frequency is outside
acceptable limits, the transfer switch activates and transfers the UPS
to battery.
Battery Charger
In Normal mode, the Battery Charger converts mains AC power into
regulated DC power to float charge the battery. It is continuously
charging the battery whenever the UPS is plugged into a power outlet
and mains power is within acceptable limits—even if the UPS is
turned OFF.
Battery
The PowerSure PST utilizes a valve-regulated, nonspillable, lead acid
battery. To optimize battery life, operate the UPS in an ambient tem-
perature of 20°-25°C (68°-77°F).
Inverter
When mains power fails, the Inverter draws energy from the battery
and inverts it into a regulated stepped sinewave supplying power for
equipment connected to the orange receptacles.

INSTALLATION
This UPS is designed for data processing equipment. Maximum load
must not exceed that shown on the UPS rating label. Do not connect
equipment that could overload the UPS or draw half-wave current
from the UPS, for example: electric drills, vacuum cleaners, laser
printers or hair dryers. Your total load earth leakage current must not
exceed 3.5 mA. Most data processing equipment meets this require-
ment if you use no more than two pieces of equipment. If uncertain
about your load, consult your local dealer, Liebert representative, or
Liebert Worldwide Support Group.
