Electrical connection
Attention: always respect the safety regulations!
Carry out a lightning risk assessment. We recommend installing a type 3/class III surge protective device (SPD) in
accordance with EN/IEC 61643-11 to ensure disconnection in the event of lightning and surges.
Check that the mains voltage is the same as that on the motor data plate.
Carry out the wiring and verification of line protections while referring to the Safety Booklet enclosed with the product and
the design of the electrical system and/or equipment.
