IMPORTANT SAFETY INSTRUCTIONS
SAVE THESE INSTRUCTIONS
• Locate the UPS near a wall outlet. Do not use an extension cord between the UPS and
the outlet.
This manual contains important instructions that should be followed during installation and
maintenance of the UPS.
• The Liebert PSP 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 On/Off button and disconnect the power cord
from the AC power supply to properly disable the UPS.
! CAUTION
To reduce the risk of fire, connect only to a circuit provided with 20 amperes
• Do not attach power strips or surge suppressors to the UPS.
• Do not attempt to service any parts inside the UPS except when replacing the batteries.
Failure to adhere to this could cause personal injury or equipment malfunction and void
the warranty.
maximum branch circuit overcurrent protection in accordance with the national
code, ANSI/NFPA 70.
• 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.

SETUP
Step 1 Inspect the Package
Step 5 Check the Site Wiring Fault Indicator
Inspect the package and the UPS upon receipt.
Notify the carrier and dealer of visible damage.
• Check the rear of the UPS to make sure the Site Wiring Fault indicator is
NOT illuminated.
The package includes:
Caution: If the Site Wiring Fault indicator is illuminated, have a qualified

The UPS has three battery backup outlets that
provide power when the UPS operates on battery. There is also one surge-only outlet (see
Figure 2 below).
• Plug the loads into the battery backup outlets
on the rear of the UPS.
See Step 8 for installation instructions.
Caution: Do not connect a laser printer to the
UPS.
Step 2 Decide Where to Place the UPS
Step 7 Connect the Network Surge Protection
The UPS must be placed indoors, protected from water, direct
sunlight and excessive heat.
The UPS has two network cable jacks for network lines
(see Figure 2 below).
Provide at least 4" (100mm) of clearance on all sides of the unit
for proper ventilation.
• Connect a single-line network cable into the network
surge protection IN jack on the rear of the UPS.
• Connect a network 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 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. Unit
can be charged in the on or off state.
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 8 Set Up Liebert MultiLink software
To start using the Liebert MultiLink software:
• Install the software.
See the Liebert MultiLink quick-start guide or 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 Liebert MultiLink user manual for operating instructions.
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.
Note: Emerson recommends connecting the USB cable directly to
the computer WITHOUT using a USB hub.

Verify that the replacement battery matches the dimensions and battery
specification.
Connect the battery leads to the new battery. Be sure to reconnect the red
wire to the positive (+) terminal and the black wire to the negative (-)
terminal.
Note: Small sparks may occur at the battery connectors during
reconnection. Take care not to short-circuit the positive and negative
battery terminals while replacing the battery.
