3.4. Electrical connection
Make sure that the characteristics of the available power supply correspond to those of your dryer, indicated
on its identification plate, and that the cable section and other line accessories can supply the necessary
power.
The machine leaves the factory with the complete electrical installation, and therefore you will only have to
remove the cover on the back of the dryer and connect each of the terminals to the three phases L1, L2, L3,
neutral N and the ground connection to the connection terminals or the general switch.
A circuit breaker and differential switch MUST be inserted between the wiring and the mains, and the
sensitivity of the differential switch must be 300 mA. Higher sensitivity, for example 30 mA, common in
domestic installations may cause operating anomalies in the machine.
Connect the three phases, neutral on the connection terminals or general switch and the protection cable to
earth on the electrical components panel according to the following table (section in mm2).
Correct earthing is essential to guarantee the safety of users and correct operation.
(1) A supplement is necessary for 60 Hz.
