I got the Prostar Inverter F1500-G0185T3C, and i need to connect it to a 3ph AC motor (380 V ac), i will also make a small panel to turn power on and off, also i need to add control signal (4-20 mA) so i can change the speed for the motor.

What breakers or contactors or other electronic parts do i need, and regarding having such control signal what do i exactly need?

Any tips or guides, are also welcomed!
Many thanks,

Dear Sir,

Thanks for using a Prostar inverter.

Please see the following answer to you:

The current of the breaker of contactor for you to switch on or off the power to our 18.5kw inverter is 60A. If you want to use change the speed of motor by analog input to the inverter, you can use a potentiometer, just connecting it with the terminal +10V, ANI and GND. If you want to change the speed by 4~20mA signal input to the inverter, you need to contact the signal source terminal with inverter terminal AN2 and GND. Hope you clear.

Any other questions, please feel free to contact me.

Best regards,
