Troubleshooting

Perform the checks shown below if the unit is operating abnormally.
If the unit continues to operate abnormally, please contact our Electronic Systems & Equipments
customer support center at _____.
Problem
The LED does not appear when
the AC input plug is connected
to commercial power and the
power switch is turned ON.
Backup is not possible.
The computer stops when a
power failure occurs.
Backup is performed too fre-
quently.
Frequent switching is performed
although a power failure does
not occur.
You hear the sound of switching.
Does not turn ON when power
switch is pressed.
The display is abnormal.
The display is unstable.
White lines occur.
Noise increases.
The battery replacement lamp
lights up or blinks, and the beep-
er sounds at 2-second intervals.
The status indicator shows
" ", and the beeper sounds at
0.5-second intervals.
The status indicator blinks
" ", and the beeper sounds

1. Make sure the AC input is securely connected to commercial power.
2. AC input overcurrent protection is activated and power is cut.
• If the black INPUT PROTECTION button pops up, there are too many con-
nected devices or there was a short-circuit with the connected devices.
Disconnect all the connected devices, press the black INPUT PROTEC-
TION switch (overcurrent protection switch), and turn on the power switch.
• If the status indicator does not display properly after you perform the above
operation, there is a problem with the unit.
(See "Interpreting beeps and displays" on page 23.)
The battery may not be fully charged.
Perform the test after charging the battery for at least 12 hours. (When an ad-
ditional battery is connected, the charging
The battery can be charged just by connecting the AC input plug to a wall out-
let. The "Power" switch can be either ON or OFF.
Variations (decrease) in the input power occur frequently. Or, noise may be in-
cluded that signifi cantly distorts the voltage waveform of the input power.
Try and check what happens when connecting the unit to a different wall out-
let (commercial power) located some distance away from the device consum-
ing a large amount of power.
This problem may occur also when you connect many devices to a plug strip
or extension cord connected to the UPS if it is a long or thin cable.
The unit does not start up when the input power supply voltage/frequency is ab-
normal. (The status indicator displays "H-", "-H", "L-", "-L", "HH" or "LL".) Check
the voltage and frequency of the input power supply.
A. Specifi cations Input Allowable voltage range, frequency see Page 63

The probable cause is noise that occurs inside the UPS.
Ground all devices connected to the UPS. Connect them to a wall outlet
(commercial power) for 3-pin plugs or connect their Grounding Terminal to the
Grounding Terminal of a wall outlet.
This problem may occur when power cords are long or placed closely or
when the UPS and devices to be backed up are placed closely. Rearrange
them.
If the UPS or devices connected to the UPS are contained in a metal rack, at-
tempt to ground the rack itself.
When the battery replacement lamp blinks: Judged as battery deterioration
by self-diagnosis test. Replace the battery as only the short backup operation
time is available.
