IMPORTANT SAFETY INSTRUCTIONS

WARNING: Do not attempt to service this product yourself except to

replace the battery. Opening or removing the cover may expose you to

dangerous voltages, even when the AC cord is disconnected from the

electrical outlet. Refer all servicing to qualified service personnel.

1. SAVE THESE INSTRUCTIONS. ADHERE TO ALL OPERATING
INSTRUCTIONS AND WARNINGS ON THE UNIT AND IN THIS MANUAL.

CONSERVER CES INSTRUCTIONS. CETTE NOTICE CONTIENT DES INSTRUCTIONS
IMPORTANTES CONCERNANT LA SÉCURITÉ.

2. Liebert Corporation neither recommends nor knowingly sells this product for
use with life support or other U.S. FDA designated “critical” devices.

3. CAUTION: A BATTERY PRESENTS A RISK OF ELECTRICAL SHOCK OR
BURN FROM HIGH SHORT CIRCUIT CURRENT. OBSERVE PROPER
PRECAUTIONS.

ATTENTION: UNE BATTERIE PEUT PRÉSENTER UN RiSQUE DE CHOC ÉLECTRIQUEÉ DE
BRULURE PAR TRANSFERT D'ÉNERGIE. SUIVRE LES PRÉCATIONS QUI S'IMPOSENT.

4. WARNING: To reduce risk of fire or electric shock, install in a temperature
and humidity controlled area free from conductive contaminants.

AVERTISSEMENT: POUR RÉDUIRE LE RISQUE D'INCENDLE OU DE CHOC ÉLECTRIQUEÉ,
INSTALLE DANS UN SECTEUR AVEC TEMPÉRATURE CONTROLÉ ET HUMIDITÉ
CONTROLÉE EXAMPT DE POLLUANTS CONDUCTEURS.

5. Operate the UPS indoors only. Protect it from moisture and install it in a
clean environment, free from flammable liquids, gases, or corrosive
substances.

6. WARNING: Do not modify cable. Consult dealer if connector does not
match equipment. UPS must be grounded at all times while in use. Turn
UPS OFF before unplugging, or the safety ground from UPS to equipment
will be removed

7. CAUTION: Output receptacles on the UPS are electrically live if the UPS is
ON, even if the UPS is not plugged in. The on/off switch on the UPS does
not electrically isolate the internal parts. To isolate the UPS, unplug it.

8. CAUTION: Ground leakage current must not exceed 2.75 milli-amperes.
Most data processing equipment meets this requirement if you use no more
than 4 pieces of equipment. Note: These instructions may be modified by
local wiring regulations.

9. Unplug the UPS and turn the power switch OFF before cleaning. Use only
water dampened cloth, never liquid or aerosol cleaners.

10. Do not plug appliances, such as hair dryers or heaters into UPS receptacles.

11. Operate the UPS only from a grounded outlet (2 wire plus ground) 120 VAC,
60 Hz.

12. The UPS is equipped with a grounded NEMA 5-15 input power plug. Do not
defeat the safety purpose of this plug. If unable to fully insert the plug into
the outlet, contact an electrician.

13. Route power supply cords so they are not walked on or pinched.

14. Never block or insert any object into ventilation holes or other openings.
Maintain a minimum clearance of four inches all around the UPS for proper
airflow and cooling.

15. Always turn OFF the UPS and unplug it before opening battery door. To
replace batteries, refer to battery replacement procedure. If you feel

unqualified to replace the battery, do not open battery door. Refer to
qualified service personnel.

INTRODUCTION & SYSTEM DESCRIPTION

Congratulations on choosing the Liebert PowerSure™. It provides continuous,
conditioned power to microcomputers and other data processing equipment.

Upon generation, AC power is clean and stable. However, during transmission, it
may be subject to load variations or accidents which cause power problems like
low voltage, voltage spikes, or complete power failure. These problems may
interrupt computer operations, cause data loss, or even damage equipment.

The UPS provides protection from many of these disturbances. It smoothes out
voltage variations and, in the event of complete power failure, it supports
equipment long enough for an orderly shutdown. These compact UPS units are
available in three ratings: 250, 400, and 600 VA. This manual includes
specifications for each model.

Normally, the UPS filters and connects AC utility input power to its AC outputs;
but when the UPS senses a power failure, it lights the battery LED (400 & 600
VA only) and provides AC power to equipment through a maintenance free,
sealed, lead acid battery.

The UPS contains a counter which automatically initiates a 15-second battery
test every 7 days and upon start-up. The UPS resets the counter after back-up
operation, manual battery test, or if the UPS is switched OFF. The operator may
perform a manual battery test by pressing the BATTERY TEST button on the
back of 400 and 600 VA models.

A control circuit monitors power input and battery condition and upon sensing a
fault, sounds an alarm and flashes a visual indication of the UPS status. In
addition, the 400VA and 600VA UPS models have a communications port which
enables the UPS to inform a computer equipped with SiteNet® software of the
power failure. SiteNet® automatically saves data and performs an orderly
shutdown. Cables and software are available as optional computer/LAN
Interface Kits. Consult your dealer for the kit suitable for your application.

CONDITIONS OF USE: The utility receptacle must be within 6 feet of the UPS.
This model utilizes a 110V to 120V AC 60 Hz supply voltage. Models are
available for other supply voltages.

Your UPS is designed to protect only Communication and Data Processing
equipment. Maximum load must not exceed that shown on UPS rating label. If
uncertain, consult your dealer or representative.

Placing magnetic storage media on top of the UPS may result in data corruption.
CAUTION: This equipment complies with Part 15, Subpart B of FCC rules for

Class B computing devices. Equipment operation in residential areas may cause
interference to radio and TV reception. The operator must take necessary steps
to correct interference.

GENERAL INSTALLATION

1. Unpack the unit and check the contents. There should be one UPS with
power cord (8) and one User’s Manual.

2. Check the items for damage. If any appear faulty or damaged, contact your
dealer immediately. Store the packaging in a safe place for possible future
shipment of UPS.

3. Place the UPS on a sturdy, dry surface in a well ventilated area away from
direct heat sources. Leave at least 4 inch (100 cm) clearance all around the
UPS to provide adequate ventilation.

4. Plug in the UPS and turn the UPS control switch (1) to ON.

5. Plugging in the UPS charges the batteries. Charge the UPS batteries for 12
hours before connecting the load equipment.

6. After charging the UPS, shut down your computer and unplug it. Plug the
computer equipment into the UPS AC outputs (7).

7. When all equipment is plugged in, the UPS is ready for normal operation.
