must
be
connected
to
a
known,
reliable
earth
ground
at
all
times
during
installation
and
service.
Refer
to
the
National
Electrical
Code
(NEC)
and
state/local
codes
for
details
on
grounding
requirements.
A
6
AWG
copper
ground

shall
be
used
to
connect
the

to
earth
ground.
•
This

Determining ONT Enclosure Location
The
SFU
ONT
can
be
mounted
outdoors
or
indoors.
In
either
case,
use
the
requirements
below
when
mounting
the
SFU
ONT:
• Proper
airflow
in
and
around
the
equipment
must
be
maintained
at
its
final
mounted
location.
Siding
and
other
building
material
should
not
be
installed
around
the
outside
of
the
enclosure
to
prevent
excessive
heat
buildup
and
ultimate
product
failure.
• The
unit
should
be
mounted
within
proximity
of
the
AC
electrical
power
meter
where
the
Multi
‐
Ground
Neutral
(MGN)
is
easily
accessible.
• The
unit
should
be
mounted
away
from
down
spouts,
permanent
water
sprinklers,
or
other
water
sources.
• Consideration
should
be
given
to
proper
clearances
for
opening
of
the
swinging
SFU
ONT
covers.
The
height
of
the
mounting
can
vary,
however
it
is
recommended
that
the
enclosure
be
installed
at
a
vertical
distance
of
approximately
four
feet
(1.2
meters)
from
grade.
This
height
lends
to
ease
of
installation/repair.
Naturally,
this
mounting
is
dependent
on
the
height
of
the
customer
provided
inside
wire
and/or
length
or
location
of
the
buried
fiber
drop,
which
is
assumed
to
enter
the
SFU
ONT
from
the
ground
upwards.
The
enclosure
is
mounted
vertically.
If
at
all
possible,
the
enclosure
should
be
surface
mounted
on
a
flat
surface.
