Power Supply And Motor - V2 HEAVY2 Manual De Instrucciones

9 - POWER SUPPLY AND MOTOR

The control unit must be powered by an electric wire protected
by a differential magnetothermic switch in compliance with
current legislation.
The control unit can drive a 230V/400V three-phase motor with
delta connection.
The power needed depends on the kind of motor used and can
be one of three kinds:
• 400V three phase
• 230V three phase
• 230V single phase
The following layouts show how the power and cables on the
motor should be connected and how the voltage selection
connector in each case should be set up.

before the motor.
