Intermittent Alarm
Possible cause
A utility failure has
occurred and the UPS
is in Battery mode.
The UPS does not
recognize the internal
batteries.
The battery voltage is
lower than the batteries
disconnected level that is
defined for this UPS. This
might be because of a
blown fuse, intermittent
battery connection, or a
battery cable is
disconnected.
The battery time remain-
ing or battery capacity is
lower than the battery
low warning level that is
defined for this UPS.
The communication to
external devices stops
because the UPS has
entered a state where it
might abruptly stop
operating without further
notice unless utility power
returns.
A weak battery string was
detected during the last
battery test.
Remark / Action
The UPS is powering
the equipment with
battery power. Prepare
your equipment for
shutdown.
Make sure that all
batteries are correctly
connected. If the
condition persists,
contact your service
representative.
This warning is
approximate. The actual
time to shutdown might
vary depending on the
UPS load and presence
of an extended battery
module.
The alarm is issued
when the battery time
remaining reaches zero.
All connected devices
should have already
shut down gracefully.
This is a warning notice.
Replace the batteries
soon.
