IMPORTANT SAFETY INSTRUCTIONS

DISCONTINUED

SAVE THESE INSTRUCTIONS

This manual contains important instructions that should be followed during installation and maintenance
of the UPS.

• Intended for installation in a temperature-controlled, indoor area free of conductive
contaminants.

• Maximum ambient temperature 104°F (40°C).

Read this manual thoroughly before attempting to install or operate this UPS.

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

CAUTION: To reduce the risk of fire, connect PS3000RT3-120 models only to a circuit provided
with 30 amperes maximum branch circuit overcurrent protection in accordance with the
National Electric Code, ANSI/NFPA 70. Other Liebert PSI models must be connected to a circuit
with 20 amperes maximum branch circuit overcurrent protection.

WARNING! Operate the UPS only from a properly grounded (earthed) 110-127VAC, 50Hz or
60Hz AC supply.
Some components are live, even when AC power is disconnected. For service, contact a
properly trained and qualified technician. Do not remove the cover; the UPS has no
user-serviceable parts inside except the internal battery pack.

WARNING! Although the UPS has been designed and manufactured to ensure personal safety,
improper use can result in electrical shock or fire. To ensure safety, observe the following rules:

Turn Off and unplug the UPS before cleaning it. Clean the UPS with a dry cloth. Do not use
liquid or aerosol cleaners.

Do not install or operate the UPS in or near water.

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 air flow.

Do not place UPS power cord anywhere it might be damaged.

Battery Handling Precautions

DISCONTINUED

WARNING! Batteries should be replaced only by properly trained and qualified personnel
knowledgeable of batteries and required precautions.

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

Remove watches, rings and other metal objects.

Use tools with insulated handles.

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

Do not open or mutilate the battery or batteries. Released electrolyte is toxic. It may cause
injury to the skin and eyes.

When replacing the battery, use the same type of battery as is listed in Table 8-1.

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

CONDITIONS OF USE —The input supply outlet must be within 6 ft. (1.8m) of the UPS and be easily
accessed.

This UPS provides conditioned power to connected equipment. It is not intended for use with life-support
and other designated “critical” devices. Maximum load must not exceed that shown on the UPS rating
label. If uncertain, consult your local dealer, local Vertiv representative or Channel Support Applications.

When installing the UPS or making input and output connections, comply with all relevant safety codes
and standards (e.g., UL 1778).

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

ELECTROMAGNETIC COMPATIBILITY—The Liebert PSI complies with part 15 of the FCC Rules.
Operation is subject to the following two conditions:

• This device may not cause harmful interference, and

• This device must accept any interference received, including interference that may cause
undesired operation.

This equipment uses, generates and can radiate radio frequency energy and, if not installed and used in
accordance with the instructions, may cause harmful interference with radio communications. However,
there is no guarantee that interference will not occur in a particular installation. If this equipment does
cause harmful interference to radio or television reception, the user is encouraged to try to correct the
interference by one or more of the following measures:

• Reorient or relocate the receiving antenna.

• Increase the separation between the UPS and the receiver.

• Connect the UPS to an outlet on a circuit different from the one the receiver is connected to.

1 INTRODUCTION

DISCONTINUED

The Liebert PSI™ is a 2U, line-interactive UPS that may be installed in a rack or used as a tower UPS.
Status indicators on the front of the Liebert PSI display load level, battery level, buck/boost, site-wiring

fault and battery status. Controls include a combination ON/ Alarm Silence/Manual Self-Diagnostic
button, an Off button and a Display Status Change button.

The Liebert PSI has USB, DB-9 (contact closure) and Liebert IntelliSlot® ports. The DB-9 and USB ports
provide detailed operating information including voltages, currents, and alarm status to the host system
when used in conjunction with Liebert MultiLink™ shutdown software.
