The variable frequency drive “VFD” should be mounted in an area not subject to damp or moist air, like an equipment room or pantry or even a closet or a salon cabinet! There are a lot of options as to where this unit can be mounted because it’s just wiring runs! Real simple! If you have to mount it in the engine room or some other area subject to damp air, obtain an approved electrical enclosure to mount it in.
Connect the provided #6 wiring leads from the thruster to terminals 1, 2, 3 inside the VFD on the right as well as the ground to the green ground terminal. The terminals on the left receive the #6 wiring leads 1 and 2 will be 240vac and ground to their respective terminals from the generator through the provided circuit breaker and enclosure. Joysticks, on/off switch and rudder sensor connectors are located on the bottom of the VFD as well as the entry grommets for the generator and thruster wiring!
