UPS
Care
and
Storage
This section explains UPS care
and
maintenance
including preventive maintenance, battery care,
and
UPS storage.
Preventive
Maintenance
The best preventive maintenance measure is to
keep the area
around
the UPS clean
and
rela-
tively
dust
free. If the atmosphere is very dusty,
clean the outside of the system periodically
with
a
vacuum
cleaner.
Battery
Life
By
keeping
the
UPS
at
an
ambient temperature
of 25°C (77°F), the full battery life can be
achieved providing that battery usage is
not
abnormal.
Battery
Recharging
If the UPS
ON/OFF
Switch is left
in
the
ON
position, the UPS automatically recharges the
battery
when
power
returns after a
power
failure. Complete recharging
can
take
up
to
24
hours
when
the battery is
used
for a long period
of time. However, most charging is done in less
than
8 hours.
Storing
the
UPS
If
you
are going to store the UPS unplugged,
tum
the UPS
ON
/OFF Switch OFF. If
you
store
the UPS for a long period, recharge the battery
every six months by plugging the UPS into a
power
outlet
and
turning
the
UPS ON. Charg-
ing
takes 8 to
12
hours. If
you
continue to store
the
UPS,
turn
the UPS OFF after charging.
