Check the grid characteristics against the 
data indicated on the plate. The 
identification plate bearing the technical 
data, serial number and brand name is 
visibly positioned on the appliance. Do not 
remove this plate for any reason.
Perform the ground connection using a wire 
that is 20 mm longer than the other wires.

ALFA310LP: The appliance is provided 
with a three-core H07RN-F cable (3 x 2.5 
mm² referring to the cross section of the 
internal conductor).

ALFA310-1: The appliance is provided 
with a five-core H07RN-F cable (5 x 1.5 
mm² referring to the cross section of the 
internal conductor).

Connection modes:

•  220-240 V 1N~

3 x 2.5 mm² three-core cable.

•  380-415 V 2N~

4 x 2.5 mm² four-core cable.

•  380-415 V 3N~

The terminal indicated by 

symbol  

links 

up 

parts that are 

normally earthed. Connect the 
appliances appropriately using this 
terminal in order to make sure that 
they are equipotential.

If the phase voltage drops below 
190V~, the performance of the 
oven may suffer, not due to the 
product itself.

The values indicated above refer 
to the cross-section of the internal 
conductor.
