IMPORTANT SAFETY INSTRUCTIONS

SAVE THESE INSTRUCTIONS

This manual contains important safety instructions that should be fol­lowed during the installation and maintenance of the Uninterruptible
Power System (UPS) and its batteries. Please read this manual thor­oughly before attempting to install or operate this UPS.

Read all safety, installation, and operating instructions before operat­ing the UPS. Adhere to all warnings on the unit and in this manual.
Follow all operating and user instructions.

This equipment is designed for Commercial, Industrial or Residential
use. Liebert Corporation neither recommends nor knowingly sells this
product for use in life support applications or with other designated
critical devices.

This equipment can be installed and operated by individuals without
previous training.

WARNING

!

SAFETY PRECAUTIONS

• To prevent the risk of fire or electric shock, install the UPS
in a temperature and humidity controlled room, free of
conductive contaminants, moisture, flammable liquids,
gases and corrosive substances.

• Operate the UPS only from a properly grounded (earthed)
120VAC, 60Hz AC supply.

• To reduce the risk of electric shock, do not remove the
cover, as it has no user-serviceable parts inside except the
internal battery pack. Some components are live, even
when AC power is disconnected. For service, contact a
qualified technician.

CAUTION

!

Although your UPS has been designed and manufactured to
assure personal safety, improper use may result in electrical
shock or fire. To ensure safety, please observe the following
rules:

• Turn off and unplug your UPS before cleaning. Do not use
liquid or aerosol cleaners. A dry cloth is recommended to
remove dust from the surface of your UPS.

• Do not install or operate your UPS in or near water.

• Do not place your UPS on an unstable cart, stand or table.

• Do not place your UPS in direct sunlight or near heat
emitting sources.

• Never block or insert any objects into the ventilation holes
or other openings of the UPS. Keep all vents free of dust
accumulation that could restrict airflow.

• Do not place the UPS power cord in any area where it may
be damaged by heavy objects.

• Placing magnetic storage on the top of the UPS may result
in data corruption.

CAUTION

!

If your UPS demonstrates any of the following conditions,
turn off and unplug your UPS from the outlet and contact
your local dealer, Liebert representative, or Liebert
Worldwide Support Group.

• The power cord is damaged.

• Liquid has been spilled on the UPS.

• The circuit breaker or fuse opens frequently.

• The UPS does not operate in accordance with the user
manual.

Provided are a Liebert MultiLink cable and a USB cable for connec­tion to a computer. Do not use the Liebert MultiLink cable for other
applications. Store in a safe place if not required at this time.

When using the communication features on this UPS, ensure the
cabling connected to the DB-9 or UPS communications ports are kept
separated from the power leads to the UPS input and output.

2

CONDITIONS OF USE: The input receptacle must be within 6 feet
(1.8 meters) of the UPS.

Your UPS provides conditioned power to connected equipment. Maxi­mum load must not exceed that shown on UPS rating label. If uncer­tain, consult your local dealer, Liebert representative or the Liebert
Worldwide Support Group.

The equipment can be installed and operated by individuals without
previous training.

CAUTION

!

BATTERY HANDLING PRECAUTIONS
Servicing of batteries should be performed or supervised by

personnel knowledgeable of batteries and required
precautions. Keep unauthorized personnel away from the
batteries.

A battery can present a risk of electrical shock and high
short-circuit current. The following precautions should be
observed when working on batteries:

• Remove watches, rings, and other metal objects.

• Use tools with insulated handles.

• Do not dispose battery or batteries in a fire. The battery
may explode.

• Do not open or mutilate the battery or batteries. Released
electrolyte is harmful to skin and eyes. It may be toxic.

• When replacing the battery, use same number and type of
battery as the suitable recommended type of battery listed
in specification table in back of this manual.

• Handle, transport and recycle batteries in accordance with
local regulations.
