Ex

are
used
in
the
dispenser
distribution
boxes.
These
bushings
have
a
cable
diameter
range
(D

)
of
7.0
mm
to
13.0
mm
(M20)
and
11.0
mm
to
17.0
mm
(M25)
.
It
is
forbidden
to
use
cables
that
have
a
diameter
outside
of
the
permitted
bushing
range!
NOTICE

>LPG
Each
LPG
dispenser
must
be
secured
with
an
electrical
device
equipped
with
the
STOP
function
according
to
category

The

must
be
familiar
with
the
device
function.
NOTICE
Pulse
overvoltage
may
occur
in
any
line
due
to
the
strike
of
lightning
up
to
the
distance
of
several
kilometres
or
due
to
any
industrial
activity.
The
size
of
pulses
formed
by
lightning
induction
is
sufficient
to
a
total
damage
of
electrical
equipment.
For
these
reasons
the
overvoltage
protection
is
used
which
diverts
energy
of
the
overvoltage
pulse
to
the
grounding
wire,
thus
protecting
the
device.
The
dispenser
manufacturer
recommends
protecting
the
main
switchboard
(or
the
secondary
switchboard)
supplying
the
dispensers,
electronic
devices
(computer,
payment
terminal,
etc.)
and
data
lines
by
overvoltage
protection
and
lightning
arresters.
The
manufacturer
is
not
responsible
for
damage
caused
by
insufficient
protection
of
cable
connections!
NOTICE
For
trouble
‐
free
operation
of
dispensers,
it
is
necessary
to
consistently
separate
signal
cables
from
power
supply
cables.
When
power
cables
are
in
the
vicinity
of
signal
cables,
the
interference
and
undesirable
parasitic
phenomena
occur
that
can
cause
problems
with
controlling
the
dispensers
or
even
destruction
of
electronic
devices
placed
in
dispensers
and
in
the
booth.
Therefore,
any
intersection
or
joint
routing
(in
one
harness)
of
signal
and
power
cables
must
be
avoided.
This
can
be
solved
so
that
power
and
signal
cables
have
their
own
"channels"
(storage,
metal
pipes).
The
manufacturer
is
not
responsible
for
damage
caused
by
improperly
performed
cable
connections!
