Statics,
Interference
Lightning
and
Surge
Protection
This
product
adopts
TVS
plate
lightning
protection
technology
to
avoid
damage
caused
by
pulse
signal
that
is
below
3000W,
like
instantaneous
lighting
stroke,
surging,
etc.
According
to
the
actual
outdoor
situation,
necessary
protection
measures
must
be
taken,
besides
ensuring
the
electrical
safety.
! The
distance
between
signal
transmission
wires
and
High-­‐voltage
equipment
or
high-­‐voltage
cable
is
at
least
50m.
! Outdoor
wiring
should
better
be
routed
under
eaves
as
much
as
possible.
! In
the
open
field,
wiring
should
be
buried
underground
in
sealed
steel
pipe,
and
the
steel-­‐pipe
should
be
one-­‐point
grounding.
Overhead
routing
method
is
forbidden.
! In
strong
thunderstorm
area
or
high
induction
voltage
areas
(such
as
high-­‐voltage
transformer
substation),
high
power
lightning
protection
apparatus
and
lightning
conductor
are
necessary
to
be
added.
! The
design
of
lightning
protection
and
grounding
of
the
outdoor
devices
and
cables
should
be
considered
together
with
the
lightning
protection
demand
of
buildings.
It
also
must
conform
to
the
related
national
standards
and
industrial
standards.
! The
system
should
be
equipotential
grounded.
The
grounding
equipment
must
conform
to
the
demands
of
system
anti-­‐jamming
and
electrical
safety
both
and
it
must
not
appear
short
circuit
or
mixed
circuit
with
the
zero
conductor
of
strong
grid.
When
the
system
is
grounded
alone,
the
resistance
should
be
no
more
than
4Ω.
The
sectional
area
of
the
grounding
cable
should
be
no
less
than
25mm2.
For
grounding
instructions,
please
refer
to
the
Installation
Manual
of
Speed
Dome.
