contactors and thermal relays and the
wires section according to the motor and
supply voltage specs.
ATTENTION:
Wiring is not supplied.
The burners are produced with
connections suitable for power supply
380-400 V three-phase.
The burners with electric motors of an
output lower or equal to 3 kW can be
adapted to 220-230 V (please follow the
instructions on the backside); motors with
higher output can only work 380-400 V
three-phase. In case of request of burners
different from the above mentioned
standard, it is recommended to make
specific mention in the order.
Instructions: how to adapt electric
motors of an output lower or equal to 3
kW to 220-230 V power supply
It is possible to change the voltage of the
burner by operating as follows:
1. change the connection inside the
electric box of the motor, from star to delta
(see picture 1);
2. change the setting of the thermal relay,
referring to the absorption values indicated
in the motor nameplate. If necessary,
replace the thermal relay with another one
of suitable scale.This operation is not
possible on motors above 3 kW.
