What It Means
The DC disconnect circuit breaker is open. If
bypass voltage is within tolerance (see
Glossary), the unit transfers to static bypass
operation. If not, the unit transfers to standby
and does not supply output voltage.
The battery monitor test has found that the
battery pack is near low runtime capacity or
that the battery pack may have a problem.
The unit's status does not change, but when
the unit operates on battery, runtime will be
seriously reduced.
The battery monitor test has found that
battery capacity is reduced (typically below
80%). The unit's status does not change, but
the unit will not be able to operate as long on
battery (it will have reduced runtime).
The bypass frequency is out of tolerance (too
high, low, or unstable). The unit may transfer
to battery or standby operation; it cannot
operate in static bypass.
The bypass voltage was momentarily out of
tolerance (see the Glossary). The unit may
transfer to battery or standby operation; it
cannot operate in static bypass.
The bypass voltage is out of tolerance (too
high or low). The unit may transfer to battery
or standby operation; it cannot operate in
static bypass.
Failure in charge regulation. The unit
transfers to battery until the "Low DC
shutdown" alarm; then, it transfers to standby
and does not supply output voltage.
The external service bypass switch is in the
line position. The unit is in standby and does
not supply output voltage. However, the
loads may be receiving power from the
external manual bypass.
At the DC disconnect, you must first
turn the precharge/discharge switch to
the precharge position and hold it until
the LED turns off. Precharge is very
important to prevent damage to your
equipment. After precharge, switch the
DC disconnect circuit breaker on.
Phone BEST's Worldwide Service to
schedule battery maintenance.
See Section 205 to display the
parameters. Then, change the "Battery
monitor reset" parameter to "ON." This
will clear the Battery Monitor Warning .
Next, do a battery monitor test (see
Section 302). If the alarm starts again,
phone BEST's Worldwide Service to
schedule battery maintenance.
Ask an electrician to make sure that the
correct input frequency is being supplied
to the UPS. If so, phone BEST's
Worldwide Service.
Ask an electrician to make sure that the
correct input voltage is being supplied to
the UPS. If so, and if this voltage is
within the range accepted by the UPS,
phone BEST's Worldwide Service.
