A Low Battery

(A)
The UPS has shut down because the battery
voltage is too low for the UPS to continue
operating on battery power. The battery
charge is low because the UPS was running
on battery power or because the DC switch
on one or more separate battery cabinets was
off.
Before this alarm sounded, you should have
received a Low Runtime alarm (D) to warn you
to shut down your equipment. Shortly after
acceptable AC input power returns, the UPS will
automatically restart and begin recharging the
batteries. Once the UPS restarts, you can restart
your equipment and resume normal operation.

The battery voltage is too high. There may
be a problem with the parameter settings,
batteries, or charging circuit.

The unit is running on battery power, but the
amount of time that it can continue to do this
is low.
Shut down your equipment and the UPS to
conserve battery power. When AC input power
returns, turn the FERRUPS on again. If you
leave the FERRUPS on after this alarm sounds,
it will soon sound alarm A and shut down, and it
will automatically restart when AC input power
returns.

Your equipment is drawing more power
(watts) than the UPS is designed to provide.
(See your model’s watt rating.) The unit will
shut down after 2 minutes.
The least important equipment should be
disconnected from the UPS. To determine how
much equipment needs to be disconnected, you
can shut off the equipment one device at a time
until the alarm stops.

The temperature inside the unit is too high. If
the temperature continues to rise, the UPS
will eventually shut down.
If the UPS has shut down, call Best Power’s
Worldwide Service or the nearest Best Power
office. If not, correct the cause of the high
temperature, and make sure nothing is blocking
the UPS vents. If you cannot correct the
problem, call Best Power’s Worldwide Service
or the nearest Best Power office.

(I)
You can start a User Test alarm by displaying
parameter (number 2 13) and pressing ¿.
There is a problem with the housekeeping
supply inside the UPS. If the green light on
the UPS front panel is blinking, the UPS has
switched to Line Condition mode, which
means it cannot operate on battery power. If
this happens, the UPS will not be able to
supply output power during a power outage.
To stop the User Test alarm, press any button on
the front panel.
Phone Best Power’s Worldwide Service or the
nearest Best Power office.
