ELECTRICAL
CONNECTION
OF
THE
DISPENSER
For
electrical
connection
of
TATSUNO
EUROPE
dispensers,
it
is
necessary
to
perform
protection
against
touch
voltage
according
to
an
international
standard
HD
60364
‐
4
‐
41:2017,
and
applicable
electrical
cables
must
be
then
routed
to
each
dispenser.
It
is
necessary
that
all
dispensers
at
the
fuel
station
are
interconnected
by
a
grounding
wire
and
connected
to
the
grounding
system.
As
a
grounding
wire
you
can
use
a
yellow
‐
green
cable
with
a
section
of
at
least
4
mm
2
or
a
special
grounding
strap.
The
grounding
wire
must
be
connected
to
a
central
grounding
terminal
of
the
dispenser
located
on
the
foundation
(bolt
M10)
marked
with
a
mark
for
grounding.
CAUTION
Only
cables
complying
with
the
requirements
of
European
standard
EN
13617
‐
1:2012
may
be
used
as
supply
cables.
The
essential
properties
of
these
cables
include
resistance
to
oils,
gasoline,
and
gasoline
vapour
(according
to
HD21
13S1).
Examples
of
electrical
wiring
are
given
in
IN041
–
Connection
plans.
NOTE
For
easy
installation
(cable
termination
in
a
distribution
box),
it
is
necessary
that
the
ends
of
all
cables
entering
the
dispenser
are
of
a
sufficient
length
–
each
end
at
least
3
m
above
ground.
In
terms
of
used
voltage
and
function
the
cables
may
be
divided
into
power
(supply)
and
signal
cables.
Power
cables:
supply
of
pump
and
vacuum
pump
electric
motors
located
in
the
dispenser
supply
of
counters,
switching
circuits
and
heating
switching
of
pumps
located
outside
the
dispenser
(pressure
version
of
the
dispenser/module)
Signal
cables:
communication
line
additional
service
and
safety
lines
(STOP
signal,
pulse
outputs,
motor
blocking,
level
gauges,
etc.)

SUPPLY
OF
PUMP
AND
VACUUM
PUMP
ELECTRIC
MOTORS
IN
THE
DISPENSER
The
supply
of
pump
electric
motors
and
vacuum
pump
electric
motors
for
all
types
of
dispensers
is
carried
out
with
the
help
of
a
4
‐
wire
H05VV5
‐
F
4x1.5
cable
(see
Table
14)
which
is
fed
from
the
main
switchboard
in
the
booth
to
each
dispenser
to
the
power
supply
box,
see
document
IN041
‐
Foundation
plans
I.
The
cable
is
connected
to
the
fuses
and
the
switch
in
the
switchboard.
Switching
of
individual
pump
motors
and
vacuum
pump
motors
is
performed
via
contactors
inside
the
dispenser.
All
TATSUNO
EUROPE
dispensers
for
gasoline
and
diesel
delivery
in
a
suction
version
are
equipped
with
contactors
and
each
motor
is
protected
by
thermal
jet
protection
in
the
dispenser.
Pump
motors
and
vacuum
pump
motors
switching
is
performed
so
that
at
any
moment
a
maximum
of
two
pump
motors
and
possibly
two
vacuum
pump
motors
are
connected
to
the
power
supply
cable.
