CONDITIONS OF USE: The mains supply socket must be within 2m (6.5 ft.) of the UPS and be eas-
ily accessible.
Your UPS provides conditioned power to connected equipment. This product is designed for Commer-
cial use only. It is not intended for use with life support and other designated “critical” devices. Maxi-
mum load must not exceed that shown on the UPS rating label. If uncertain, consult your local dealer,
Liebert representative or the Liebert Worldwide Support Group.
The PSI 1000 VA, and 1440 VA models are not supplied with an input power cable for connection to
the mains supply socket. Use the input mains supply power cable from your data processing equip-
ment to connect the UPS to the mains supply.
For the 2200 VA and 3000VA models, use the supplied 16A-rated input mains supply cables. For UK
supply systems, consult a qualified electrician to connect the lead supplied for the 2200 VA and
3000VA models to the mains supply.
When installing the UPS or making input and output connections, comply with relevant safety codes
and standards (e.g. IEC60950, VDE0805, EN62040-1).
Placing magnetic storage media on top of the UPS may result in data corruption.
The equipment can be installed and operated by individuals without previous training.
Electromagnetic Compatibility—The PowerSure™ PSI series complies with the requirements of
the EMC Directive 89/336/EEC and the published technical standards. Continued compliance requires
installation in accordance with these instructions and use of Liebert-approved accessories only.
Environmental-Operate the UPS in an indoor environment only in an ambient temperature range of
0°C to 40°C (32°F to 104°F). Install in a clean environment, free from conductive contaminants, mois-
ture, flammable liquids, gases, or corrosive substances.
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.

CAUTION
The UPS and connected load total earth leakage current must not exceed 3.5mA. If the
connected load earth leakage current is likely to exceed 2.5mA or you are unsure, then convert
the input cable attachment to either a fixed wiring installation or an industrial plug/socket
(e.g., CEE 17 connector). This alteration should be carried out by a competent electrical
engineer who is conversant with local electrical codes and regulations.
!
CAUTION
DO NOT CONNECT equipment that could overload the UPS or demand half-wave
rectification from the UPS, for example: electric drills, vacuum cleaners, laserjet/inkjet
printers, hair dryers, overhead projectors.
!
CAUTION
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 is toxic.
• When replacing the battery, use same number and type of battery as the suitable recom-
mended type of battery listed in Table 3.
• Handle, transport and recycle batteries in accordance with local regulations.
