Liebert® PSP

Quick-Start Guide - 350VA/500VA, 120V

IMPORTANT SAFETY INSTRUCTIONS

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).

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.

• 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

™

• Locate the UPS near a wall outlet. Do not use an extension cord between the UPS and
the outlet.

• 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.

• 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.

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. 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 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

• 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. 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.

Caution: Do not connect a laser printer to the
UPS.

Step 7 Connect the Network Surge Protection

The UPS has two network cable jacks for network lines
(see Figure 2 below).

• 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 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.

Note: Emerson recommends connecting the USB cable directly to
the computer WITHOUT using a USB hub.

REPLACING THE BATTERY

Servicing of batteries should be performed or supervised by personnel knowledgeable about batteries and required precautions.

When replacing batteries, replace with the same type and size battery.

CAUTION

!

Do not dispose of batteries in a fire. The batteries may explode.

CAUTION

!

Do not open or mutilate batteries. Released electrolyte is harmful to the skin and eyes. It is toxic.
This product is designed for 120V equipment.

To replace the battery:

1. Turn off all connected loads, then turn off the UPS and unplug the input
power cord. (Batteries are NOT hot-swappable.)

2. Carefully lay the UPS on its left side, as shown in the diagram.

3. Use a #1 Phillips head screwdriver to remove the four screws from the
right-side cover, then pull up the right-side cover and remove it.

4. Remove the black wire from the negative (-) terminal and the red wire from
the positive (+) terminal.

5. Gently remove the battery from the UPS.
Attention: Risk of Electric Shock.

6. Verify that the replacement battery matches the dimensions and battery
specification.

7. 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.

8. Place the battery in the UPS.

9. Ensure correct alignment of front panel, then reattach the right-side cover.
Evenly tighten the four screws from Step 3. (Do NOT over tighten screws)

Dispose of the old battery properly at an appropriate recycling facility.
