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

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)

 

A flourescente lamp is located vertically on the right-
hand 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.
