2 - ELECTRICAL SYSTEMS - CONNECTIONS - CONFIGURATIONS
The machine is designed to operate under a single-phase voltage of 230 V AC (+5-10V)
It is protected with two T 6,3 A fuses on both phases.
A safety transformer supplies power to very-low voltage components (24 V DC), while the cooling unit and
the Flourescent lamp are powered with the mains voltage.
With regard to the safety transformer:
The primary winding is protected with a T 800 mA fuse
The secondary winding 25 V is protected with the following fuses:: T 1 A – T 4 A
The slide-out compartment door is fitted with a bipolar safety switch.
The switch is located on the front panel of the power supply unit, and when opening the compartment it
disconnects the power from all parts that can be accessed for normal maintenance and cleaning operations.
The only parts that stay energised are those protected by suitable covers carrying a plate with the warning
"Disconnect power before removing the cover”; to clear the voltage the power the power supply cable
must be disconnected from power outlet
or in the case of connection to a dedicated power board, it should
be set to OFF
The power cable can be supplied as standard feature and chosen
among the following types:
HO5 RN – F copper with a 3 x 1.5 mm
2
section
1) HO5 VV – F ,, ,, ,, ,,
2) HO7 RN – F ,, ,, ,, ,,
In all configurations the cable is fitted with a SCHUKO plug
permanently fixed to the cable
NOTE :
In the event of replacement cables of exactly the same
characteristics must be used.
Since the “SFERA” vending machine is approved by an
electrical safety certification institute (IMQ), replacements
with non-original components are not permitted.
Otherwise the electrical safety certificate and the warranty will
be void.
ACTUATION BOARD AND CONNECTIONS
(Electrical compartment open)
flourescente lamp is located vertically on the righthand side inside the cabinet; the starter is fitted
inside the lamp holder. (see page 12)
The ballast is located inside the power supply
compartment.
The CPU board controls also the 24 V actuations by
means of TRIACs and Darlington switches, while the
lamp and the cooling unit are controlled by a relay
card located inside the power supply compartment.
(see page 12)
Some versions are provided with monitoring of the
selected product fall into the dispensing
compartment by means of a card with
receiver/transmitter diodes (infrared).
If during a selection the barrier is not interrupted it
means that a product is finished or jammed, in this
case the system will further attempt releasing the
product with small rotations; if also this fails the
selection is disabled and the customer is entitled to a
new selection.
