Battery temperature is
too high and charging
stops.
The battery is not
connected. Or, the
battery has been
remarkably degraded.
Ambient temperature of
the UPS may be too
high. Check the
ambient temperature of
the UPS. If the
temperature is over 40
degrees C, lower the
ambient temperature.
Turn off all power
switches of this unit
and connected devices,
and turn on the power
of this unit only again. If
the temperature is 40
degrees C or lower, this
unit might be out of
order. Please contact
the shop of purchase..
Connect the battery. If
this message appears
while the battery is
being connected,
replace the battery.
Select an item
corresponding to
"The contents of the
UPS fault" among the
displayed messages
and follow the
instructions.
Turn OFF the power
switches of all devices
connected to the unit,
reduce the number of
connected devices, and
turn the power switch
back ON again.
Note: The connection
capacity can be
monitored with
“Measure-ments”-“Load
Meter”.
There are too many
connected devices and
the rated capacity is
exceeded
Commercial power is
being output directly in
Bypass Mode.
Note 1: During normal operation the messages of the either normal mode, AVR mode, or ECO
mode are displayed by turns. During battery mode the messages of the battery mode
are displayed by turns.
If 100% of rated capacity is exceeded under commercial operations, the bypass
operation starts in 5 minutes. If 115% is exceeded, the operation immediately stops.
If 105% of rated capacity is exceeded under backup operations, the output stops in 30
seconds. If 125% is exceeded, the output immediately stops.
Note 2: Not dependent on the state
Note 3: For details, see "■ The contents of the UPS fault".
