EMS Installation Question

When installing a Progressive Industries EMS-HW30C are there any negatives to completely removing the heavy shore power cable and just use romex from the plug to the input of the EMS and then wire in the existing romex to the output? It would make for a much easier and cleaner looking install not having to deal with that black cable.

I could remove the metal box as well and just set the EMS there could I not?

I would stick with the cable. It has several advantages: The biggest is it's very well protected. And I would attach the terminated wires to a terminal block with ring lugs and use that as my connection point. The terminal block could be mounted inside a weather proof junction box, Plastic not metal. On those ring lugs I would use heat shrink at the barrel ends to keep moisture out and corrosion at bay.

This will allow much easier access if you need to disconnect the system at some future point.

Good Luck
