Description
No AC input.
Operation stopped.
There is AC input.
Power switch is OFF.
Power switch is ON.
Operating normally.
Self-diagnostic test in progress.
Auto battery test in progress.
In Battery Mode due to power
failure or AC input error.
Output will stop if Battery
Mode continues.
(Same as above.)
Battery level is low, so output
will soon stop.
Battery is dead,
so output stopped.
(This is displayed only for
a few seconds.)
AC input voltage is too high
(over).
AC input frequency is too
high (over).
AC input voltage is too low
(under).
AC input frequency is too
low (under).
There are too many connected
devices and the rated capacity is
exceeded. If this state continues
for as long as or longer than the
times described below,
commercial power continues
to be supplied through bypass
operation (Note 1).
or ・When connection capacity is
at 100% or higher: Bypass
operation begins after 10 seconds
・When connection capacity is
at 120% or higher: Output stops
after 1 minute (Go to No.12)
・When connection capacity is
at 140% or higher: Output stops
after 10 seconds (Go to No.12)
Output stopped due to
or
exceeded connection capacity.

(Same as above.)
Charge the battery.
Use within the AC input
voltage/frequency range
described in the specifications.
→ See Page 90
(Same as above.)
Reduce the number of connected
devices until the display appears
as in status No. 3.
Turn OFF the power switches of
all devices connected to the unit,
