2. Connect
the
DC
power
cable
to
the
48
Vdc
connector
on
the
DRU
(see
Figure
16).
3. Locate
the
AC
power
cord
which
is
provided
with
the
AC/DC
power
converter.
Use
only
the
AC
power
cord
provided
with
the
power
converter
or
an
equivalent
UL/CUL
listed
and
certified
3-conductor,
18
AWG
cord
terminated
in
a
molded-on
plug
cap
rated
125
V,
15
A
with
a
maximum
length
of
6
feet
(1.8
m).
Note:
The
AC/DC
converter
is
intended
to
be
used
with
a
3-wire
grounding
type
plug
which
has
a
grounding
pin.
Equipment
grounding
is
to
ensure
safe
operation.
Do
not
defeat
the
grounding
means.
Verify
converter
is
reliably
grounded
when
installed.
4. Connect
the
receptacle
end
of
the
power
cord
to
the
AC
connector
on
the
AC/DC
converter
(see
Figure
17).
5. Route
the
plug
end
of
the
power
cord
to
the
specified
AC
outlet
(per
the
system
design)
and
connect
plug
to
outlet.
Warning:
Be
sure
to
check
the
nameplate
rating
of
the
AC/DC
converter
to
avoid
overloading
circuits
which
may
cause
damage
to
over-current
protection
devices
and
supply
wiring.
6. Verify
that
the
STATUS
LED
on
the
DRU
turns
red
or
blinking
red.
This
indicates
that
the
DRU
is
powered
but
not
receiving
a
forward
path
optical
signal.
Note:
Early
versions
of
the
DRU
use
a
steady
red
LED
to
indicate
all
major
fault
conditions
including
no
optical
signal
received.
Later
versions
of
the
DRU
use
a
blinking
red
LED
to
indicate
no
optical
signal
received.
7. Dress
and
secure
both
power
cables
per
standard
industry
practice.
8. When
the
installation
of
the
DRU
is
completed,
refer
to
Section
4
of
the
Digivance
ICS
Installation
and
Operation
Manual
(ADCP-75-110)
for
the
