The output of the UPS is stopping.
If an input power supply returns,
the UPS will become the stopping

the stopping (No.3) even if an input
power supply returns, check
whether or not the input breaker
has tripped. If the breaker has
tripped, reset it. If the UPS still
does not become the stopping

which you purchased the UPS or a
maintenance company.
When the UPS stopped since the

electric discharge of a battery was
completed, the UPS will return to
the normal operation (No.1)
automatically if an input power
