USER’S MANUAL
Section 4: BASIC OPERATION & INSTALLATION 60
It
is
essential
that
the
third
“grounding”
pin
not
be
defeated
on
the
power
cord
and
that
the
power
cord
be
connected
to
a
properly
grounded
receptacle.
If
a
grounded
receptacle
is
not
available,
a
qualified
electrical
contractor,
familiar
with
the
regulations
in
your
area,
should
be
contracted
to
provide
one.

IMPORTANT!
As with any piece of modern electronic gear, it is advisable that precautions be taken to
prevent damage caused by power surges. Standard line surge protectors can be used to
offer some degree of protection. It is the user’s responsibility to ensure protection
adequate for their conditions is provided (see above).
e
WARNING!
This equipment is designed to be operated from a power source that includes a third
“grounding” connection in addition to the power leads.
Do not defeat this safety feature. In addition to creating a potentially hazardous situation,
defeating this safety ground will prevent the internal line noise filter from functioning.
w
IMPORTANT SAFETY INFORMATION!
If fuse replacement is required, please note: For continued protection
against fire, replace fuse only with same type and value. See the DETAILED
TECHNICAL INFORMATION section for information and cautions.

ISDN Lightning Protection
The
single
biggest
source
of
failures
of
Telecom
equipment
is
due
to
damage
related
to
lightning.
Some
failures
are
catastrophic
failures,
while
some
are
due
to
the
cumulative
damage
that
can
occur
over
the
course
of
several
years.
For
this
reason,
we
also
recommend
that
in
addition
to
AC
(mains)
power
protection
(see
above),
that
a
quality
telephone
line
s
‐
stage
surge
protector
be
employed
at
the
back
panel
of
the
Zephyr
Xstream.
The
ground
terminal
of
this
device
should
be
connected
directly
to
the
Zephyr
Xstream
chassis,
and
the
protector
connected
to
the
Xstream’s
ISDN
Interface
jack
with
as
short
a
cable
as
possible
(under
8
inches).
This
approach
is
particularly
well
suited
to
situations
where
you
expect
nearby
strikes,
such
as
when
you
are
located
near
a
tower.
