General
Safety
Precautions
CAUTION!
Wet
conditions
increase
the
potential
for
receiving
an
electrical
shock
when
installing
or
using
electrically
powered
equipment.
To
prevent
electrical
shock,
never
install
or
use
electrical
equipment
in
a
wet
location
or
during
a
lightning
storm.
CAUTION!
This
system
is
a
RF
Transmitter
and
continuously
emits
RF
energy.
Maintain
a
minimum
8
‐
inch
(20
cm)
clearance
from
the
antenna
while
the
system
is
operating.
Whenever
possible,
shut
down
the
RAN
before
servicing
the
antenna.
NOTE:
RAUs
are
suitable
for
use
in
environmental
air
space
in
accordance
with
Section
300
‐
22(c)
of
the
National
Electrical
Code,
and
Sections
2
‐
128,
12
‐
010(3)
and
12
‐
100
of
the
Canadian
Electrical
Code,
Part
1,
CSA
C22.1.
CAUTION!
Install
RAUs
in
indoor
locations
only.
Do
not
connect
an
antenna
installed
in
an
outdoor
location
to
a
RAU,
unless
it
is
in
an
approved
AOC
weatherproof
NEMA4
housing.
CAUTION!
Attach
all
RAUs
securely
to
a
stationary
object
(that
is,
a
wall,
pole,
or
ceiling
brackets).
To
mount
a
RAU
securely
to
a
wall,
ceiling
bracket,
or
pole,
use
#6
diameter
fasteners
in
the
four
slotted
mounting
holes.
CAUTION!
Do
the
following
to
maintain
proper
ventilation:
•
Keep
at
least
76
mm
(3
‐
inch)
clearance
around
the
RAU.
•
Do
not
stack
RAUs
on
top
of
each
other.
•
Always
mount
the
RAU
with
the
solid
face
(containing
the
mounting
holes)
against
the
mounting
surface.
NOTE:
You
can
place
the
RAU,
without
its
fastening
hardware,
on
a
flat
surface,
such
as
a
shelf,
desk,
cabinet,
or
any
other
horizontal
surface
that
allows
stable
placement,
with
the
mounting
base
facing
down
to
the
mounting
surface.
CAUTION!
If
installing
the
RAU
on
a
flat
surface,
the
surface
must
be
able
to
hold
a
minimum
7
‐
pound
load
securely.
Do the following, in the order presented, to mount the RAUs and antennas:
1
Mount all MRAU and SRAUs in the locations marked on the floor plans.
2
Install the passive antennas according to the manufacturer’s installation instructions.
NOTE:
It
is
common
practice
to
install
passive
antennas
below
the
ceiling.
If
you
install
a
passive
antenna
above
the
ceiling,
when
estimating
the
antenna
coverage
area,
account
for
additional
loss
due
to
the
ceiling
material.
