SAVE THESE INSTRUCTIONS

This manual contains important instructions that should be followed during 
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 

to this could cause personal injury or equipment malfunction and void the warranty.

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 battery 
(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.
