4. Make
power
connections
to
the
Total
Access
838.
a. Determine
which
fuse
pairs
are
to
supply
power
to
the
Total
Access
838.
b. Remove
the
fuses
from
the
A
and
B
slots
for
the
pair.
c. Connect
RET A
,
PWR A
,
RET B
,
and
PWR B
to
the
power
connector.
PWR
refers
to
respective
–48
VDC
or
±24
VDC
power
sources;
RET
refers
to
respective
returns.
NOTE
♦
A
readily
accessible
disconnect
device,
such
as
a
rackmount
fuse
and
alarm
panel
that
is
suitably
approved
and
rated,
should
be
incorporated
into
the
fixed
wiring.
♦
Connect
to
a
reliably
grounded
–48
VDC
or
±24
VDC
source
that
is
electrically
isolated
from
the
AC
source.
♦

or

WARNING
!
Installing
fuses
in
the
fuse
and
alarm
panel
at
this
stage
will
provide
power
to
the
Total
Access
838.
There
will
be
power
to
pins
and
connectors
on
the
rear
panel
and
inside
the
Total
Access
838.
Exercise
caution
to
avoid
electrical
shock.
5. Apply
power
and
check
voltages.
a. Install
appropriate
fuses
in
the
slots
of
the
fuse
and
alarm
panel
that
serves
the
Total
Access
838.
b. Using
a
voltmeter,
verify
that
the
operating
voltage
is
within
the
specifications
for
A
or
B
power
feeds.
For
more
information,
refer
to
Specifications.
6. Remove
the
protective
cover
from
the
alarm
wire
wrap
terminals.
7. Connect
the
AC ALM
(AC
alarm),
CRIT
(critical),
MAJOR
,
and
MINOR
alarm
leads
from
the
alarm
panel
to
the
Common
(
C
),
Normally
Open
(
NO
),
and
Normally
Closed
(
NC
)
wire
‐
wrap
terminals
on
the
Total
Access
838
rear
panel
as
required.
NOTE
The
AC
alarm
input
functions
as
follows.
All
voltages
described
below
are
measured
with
respect
to
the
return
(
RET
)
input
to
the
Total
Access
838.
♦
When
power
is
negative
(e.g.
–48V),
the
alarm
is
triggered
when
the
voltage
on
the
AC
alarm
pin
is
at
least
5V
above
the
potential
on
the
PWR
input.
For
example,
if
the
voltage
on
the
PWR
input
is
–54V,
then
the
alarm
will
trigger
if
the
voltage
on
the
AC
alarm
pin
is
between
–49V
and
0V
with
respect
to
RET
.
♦
When
power
is
positive
(e.g.
24V),
the
alarm
is
triggered
when
the
voltage
on
the
AC
alarm
pin
is
at
least
5V
above
the
RET
input.
For
example,
if
the
voltage
on
the
PWR
input
is
+24V,
then
the
alarm
will
trigger
if
the
voltage
on
the
AC
alarm
pin
is
between
5V
and
24V
with
respect
to
RET
.
