Storing
the
uninterruptible
power
supply
and
batteries
If
you
store
the
uninterruptible
power
supply
for
a
long
period,
recharge
the
battery
every
6
months
by
connecting
the
uninterruptible
power
supply
to
a
power
outlet.
The
batteries
charge
to
90%
capacity
in
approximately
3
hours.
However,
you
should
charge
the
batteries
for
24
hours
after
long-term
storage.
Check
the
battery
recharge
date
on
the
shipping
carton
label.
If
the
date
has
expired
and
the
batteries
were
never
recharged,
do
not
use
the
uninterruptible
power
supply.
Contact
your
technical-support
representative.
Replacing
the
electronics
module
(for
trained
service
technician
only)
The
electronics
module
can
be
hot-swapped
for
replacement
without
losing
power
to
the
connected
devices.
The
uninterruptible
power
supply
automatically
switches
to
Bypass
mode.
Battery
mode
is
not
available;
however,
the
utility
power
continues
to
be
passively
filtered
by
the
uninterruptible
power
supply.
To
replace
the
electronics
module,
complete
the
following
steps:
1.
Disconnect
the
extended
battery
module
cable,
the
remote
emergency
power-off
cable,
and
the
DB9-to-RJ-45
cable,
if
installed.
2.
If
the
uninterruptible
power
supply
is
installed
in
a
rack,
remove
the
uninterruptible
power
supply
from
the
rack
and
set
it
on
a
level
surface.
3.
To
remove
the
uninterruptible
power
supply
bezel,
grasp
the
left
and
right
sides
of
the
bezel
and
pull
it
off.
4.
Remove
the
two
screws
on
the
left
of
the
electronics
module.
Firmly
grasp
the
module
and
pull
it
out
of
the
bay.
Note:
To
prevent
power
loss
to
the
connected
devices,
follow
step
5
closely.
5.
While
inserting
the
new
electronics
module,
press
and
hold
the
Alarm
reset
button
for
approximately
five
seconds
or
until
the
front
panel
LEDs
are
lit
individually.
Note:
If
the
five
load
level
LEDs
are
flashing,
the
electronics
module
might
not
be
seated
correctly.
Remove
and
reinsert
the
module
as
described
in
this
step.
