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)
- When 110% or higher: Bypass
operation begins after 5 minutes
(Go to No.19)
- When 150% or higher: Output
stops immediately (Go to No.20)
Reduce the number of
connected devices until the
display appears as in status
No. 3
Note 1: In bypass operation, commercial power is output directly.
Output stops when a power failure (AC input OFF) occurs in bypass operation.
Note 2: The displays and operations vary according to the status.
