Electrical Connection Of The Dispenser; Supply Of Pump And Vacuum Pump Electric Motors In The Dispenser - tatsuno OCEAN TOWER Series Installation And User Manual

Fuel Dispensers TATSUNO EUROPE ‐ Installation and User Manual , revision 10, January 2022
3.5. 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
2
4 mm 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.)
3.5.1. 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.
