Cause Action
・ The UPS
cannot be
powered on.
・ Power is not
output to the
secondary side
(connected
device side).
・ No response
even when the
power switch is
pressed.
None OFF ON AC input error-VH The input voltage or frequency is low
or high.
Select [Measurement] - [Input and
Output] and check the
voltage/frequency of the input power
supply.
AC input error-VL
AC input error-FH
AC input error-FL
None OFF ON Remote signal stopped The remote ON/OFF terminal has a
short-circuit or the setting for "Remote
ON/OFF Logic" on the LCD menu is
changed to "OFF when opened".
Refer to "6 Using the contact I/O
functions".
Unable to back
up
None ON ON bE Undercharged Connect the UPS to commercial power
and charge it for 4 hours or longer.
The connected
devices stop
when a power
outage occurs.
2-second

ON ON Fault-E10
(Battery Replace
LED lit)
Battery deterioration is detected. Hold down the "ESC" switch for 0.5
seconds or longer to stop the buzzer.
Replace the battery.
Get an optional replacement battery,
and you can replace the battery on
your own.
An error occurs
in power
recovery after a
power outage.

ON OFF Fault-E12 An abnormal battery temperature is
detected.
Wait until the battery temperature
drops.
The sound of the
fan became
annoying (the
rotation speed
increased).
None Undefined
(Note 3)
Undefined
(Note 3)
Undefined (Note 3) The fan operates in high-speed mode
in any of the following states.
1) When in backup operation
2) When AVR (automatic voltage
regulator) is running
Wait until the condition for running in
high-speed mode is released.
・ Clicking noise
occurs.
・
Clicking noise
is originating
from the UPS,
though a
power outage
does not occur.
None ON ON AVR mode The input power is fluctuating
frequently or noise that can distort the
wave form of the input power is
contained.
Check the environment in which the
UPS is installed.
(Such as whether a thin extension
cable is used and whether the UPS
and a device with large power
consumption are connected to the
same commercial power supply outlet.)
Note 1: Commercial power is output as-is during bypass operation. When the mode cannot shift to bypass
operation, or when a power outage (AC input turned OFF) occurs during bypass operation, output stops.
Note 2: A maximum of two types of messages may be displayed alternately on the LCD.
Note 3: The output (charging, LCD display message) is different depending on the situation.
