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.

OPTION SWITCH SETTINGS
On the back of your UPS is a bank of option switches (6) with a removable
plastic cover. These switches determine transfer levels and operating frequency.
Slide the switches to the left to turn them OFF, to the right to turn ON. Turn OFF
equipment and UPS and unplug the UPS prior to changing switch settings, or the
UPS will ignore the new settings. Replace the plastic option switch cover.
Option Switch 1: 50/60 Hz Select – When OFF, this switch sets UPS for 60 Hz
utility. Output in backup mode will be 60 Hz. When ON, the switch sets UPS for
50 Hz utility and output in backup mode is 50 Hz. The switch must match the
utility frequency or the UPS will not start. The factory setting is 60 Hz.
Option Switch 2: High Line Transfer –
250VA model: When ON, this switch transfers the UPS to battery operation
when the utility voltage reaches 135 VAC. When OFF, the UPS will not
transfer to battery. Factory setting is ON.
400/600VA models: You may select at which voltage the UPS will transfer
to battery operation when it encounters a high utility voltage. The ON
position transfers the UPS to battery operation at 135VAC; the OFF position
transfers at 140VAC. Factory setting is 135 VAC.
Option Switch 3 & 4: Low Voltage Transfer Select – Low voltage transfer is
the voltage level at which battery operation starts. You may set the low voltage
transfer of the UPS to 90V, 95V, or 100V. The factory setting is 95V. This option
reduces excessive battery usage in brownout conditions. Make sure your
computer equipment can operate at 90 VAC before selecting the lowest limit
(most will). Refer to the tables below to change switch settings:

BATTERY TEST BUTTON
The Battery Test Button (5) on the 400 and 600 VA models tests the condition of
the battery. If the charge is sufficient, the UPS lights the Battery Light (2), runs
on battery power for 15 seconds, then returns to utility power. If the battery fails
the test, the Check Light (3) illuminates and the UPS immediately returns to utility
power. The Check Light remains lit while on utility power. A battery in
unacceptable condition requires recharge or replacement of the battery.
Pressing the Battery Test Button (5) also silences alarms.

BATTERY CARE AND USE
STORAGE: If the unit is not in continued use, plug in the UPS every 4 to 6
months for 12 hours to recharge the battery. Warranty is void if the battery
discharges below the minimum battery cutoff point. To prevent such discharge,
DO NOT leave UPS ON for more than two days without plugging it in.
BATTERY LIFE & REPLACEMENT: Excessive battery use, storage at high
ambient temperatures, and lengthy periods in a discharged state greatly reduce
battery life. Your UPS maximizes battery life by limiting the depth of battery
discharge. You may replace the UPS battery yourself, but if you feel unqualified,
refer battery replacement to qualified personnel. Contact your local dealer or call
Liebert for a replacement battery.
WARNING: To replace batteries, turn OFF UPS and unplug it from utility supply.
CAUTION: Observe proper precautions. When replacing batteries, use the
same number and type of batteries. Proper battery disposal required. Refer to
local codes for disposal requirements. DO NOT OPEN OR MUTILATE
BATTERY. RELEASED ELECTROLYTE IS HARMFUL TO SKIN AND EYES
AND IS TOXIC.
To Replace the Battery:
1. Close active programs and turn off
computers.
Turn OFF the UPS and
unplug it from utility supply.
2. Place UPS on its side and remove retaining
screws (A) to battery door (B).
3. Open battery door (B) and remove the
battery (C) by pulling on the battery tab (D).
4. Remove terminal wires (E) from old battery.
Connect terminal wires (E) to new battery
(C); the red connects to the positive
terminal, the black connects to the
negative. DO NOT reverse terminal
connections. Slide battery (C) into unit, and
close battery door (B). Dispose of used
battery properly (it contains lead and acid).
5. Plug in UPS, turn it on, and charge

RESETTING THE CIRCUIT BREAKER
If the UPS is overloaded, the circuit breaker (9) at the lower rear of the UPS
activates to protect the UPS. If the circuit breaker activates, its center bar will
extend. To reset the circuit breaker, simply push the bar back in. If the circuit
breaker activates often, ask your dealer to check the UPS sizing or call Tech
Support at 1-800-222-5877.
ALARM CONDITIONS
The 400 VA and 600 VA models sound alarms and flash visual indications at the
front panel LED's (2, 3, 4) whenever they sense a power failure, low battery
voltage (while on battery), an overload, or a utility overvoltage condition. The
250 VA model only sounds an alarm. Sometimes, a fault in your computer
equipment may cause an overload alarm. See following page for alarm
indications.
You may silence the On-Battery alarm on 400 VA and 600 VA models by
pressing the BATTERY TEST button (5), on the rear panel. You must turn off
your computer equipment and then turn off the UPS to silence an alarm on a 250
VA model.
