I would like to check if any one tested the following inverter in Saudi Arabia or any GCC country, we are providing solar solutions, and looking to expand to GCC countries.

The proposed model is:

Thank you

Hello guys  :038: . We would like to upgrade a conveyor in our plant, we would like to add a VFD to regulate its speed and make smooth changes in speed.
 :dft008: :008: :045:
The problem is that the conveyor is 180 meter away from the control room  :016: , and I know that the maximum distance between VFD and motor is 50m  :51: .

What do you suggest?  :55:
