installation and maintenance of the UPS.
• Intended for installation in a controlled environment.
• Maximum ambient temperature 104°F (40°C).
• Do not connect equipment that may overload the UPS or demand half-wave
rectification, such as a laser printer.
• Connect the UPS only to an earthed / grounded outlet that meets national and local
electrical safety guidelines.
• Locate the UPS near a wall outlet. Do not use an extension cord between the UPS and
the outlet.
• The Liebert PSA has been designed for small office/home office use only; it is NOT
recommended for use in life-support applications.
• In the event of an emergency, press the OFF button and disconnect the power cord
from the AC power supply to properly disable the UPS.
• Do not attach power strips or surge suppressors to the UPS.
• Do not attempt to service any parts inside the UPS except the batteries. Failure to adhere

UPS CONTROLS AND CONNECTIONS
!
CAUTION
To reduce the risk of fire, connect only to a circuit provided with
20 amperes maximum branch circuit overcurrent protection in
accordance with the national code, ANSI/NFPA 70.
Step 1 Inspect the Package
Inspect the package and the UPS upon receipt. Notify the carrier and dealer of visible
damage.
Step 2 Decide Where to Place the UPS
The UPS must be placed indoors, protected from water, direct
sunlight and excessive heat.
Provide at least 4" (100mm) of clearance on all sides of the unit
for proper ventilation.
Step 3 Charge the UPS Battery Before
Use
The UPS battery is not charged before shipping. It MUST be charged before use.
• Connect the UPS power cord to a wall outlet and charge for at least eight hours.
Note: If battery is placed in storage, charge the battery every six months if kept at
5°F to 85°F (-15°C to 29°C)—or every three months if kept at 86°F (30°C) or higher.
Step 4 Start the UPS
After the battery is fully charged:
• Turn on the UPS by pressing the On/Off button (see Figure 1 below).
LED 1 should be illuminated (green), indicating the UPS is operating in Normal Mode.
Step 5 Check the Site Wiring Fault Indicator
See figure at right for the location of the Site Wiring Indicator on the rear of
the UPS.
• Check the rear of the UPS to make sure the Site Wiring Fault indicator is
NOT illuminated.
Caution: If the Site Wiring Fault indicator is illuminated, have a qualified
electrician check the wall receptacle wiring and fix any problems.
Step 6 Connect the Loads
The UPS has three battery backup outlets that
provide power when the UPS operates on bat-
tery (see Figure 2 below).
• Plug the loads into the battery backup outlets
on the rear of the UPS.
Caution: Do not connect a laser printer to the
UPS.
Step 7 Connect the Network Surge Protection
The UPS has two RJ-45 jacks for network lines (see
Figure 2 below).
• Connect a single-line network cable into the RJ-45
network surge protection IN jack on the rear of the
UPS.
• Connect an RJ-45 cable from the OUT jack on the
rear of the UPS to a port on a PC or network device
such as a router.
Step 8 Set Up Liebert shutdown software
To start using the Liebert shutdown software:
• Install the Liebert shutdown software. See the software
user manual for installation instructions.
• Connect one end of the USB cable (supplied) to the USB
port on the rear of the UPS. Connect the other end to a
USB port on the computer. See the software user manual
for operating instructions.
