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
mains. Output in backup mode will be 60 Hz. When ON, the switch sets UPS for
50 Hz mains and output in backup mode is 50 Hz. The switch must match the
mains frequency or the UPS will not start. The factory setting is 50 Hz.
Option Switch 2: High Line Transfer –
250VA model: When ON, this switch transfers the UPS to battery operation
when the mains voltage reaches 270 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 mains voltage. The ON position
transfers the UPS to battery operation at 270VAC; the OFF position transfers at
280VAC. Factory setting is 270 VAC.

Option Switch 3 & 4: Low Voltage Limit Select – Low voltage limit is the
voltage level at which battery operation starts. You may set the low voltage limit
of the UPS to 180V, 190V, or 200V. The factory setting is 190V. This option
reduces excessive battery usage in brownout conditions. Make sure your
computer equipment can operate at 180 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 mains power. If the battery fails
the test, the Check Light (3) illuminates and the UPS immediately returns to
mains power. The Check Light remains lit while on mains 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 mains 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.

(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 batteries
for 8 to 10 hours.
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 the number listed at the end of this manual.
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 mains 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.
Refer to the first table on the next page for recommended actions when alarms
occur. Check this table first before calling for assistance. It diagnoses and
solves common problems, and helps prevent potential problems.
