I have installed a new PRS 96x48 between yesterday and today. It was a good experience. I am stuck now because I seem to be missing the blue connectors in the control box. Also I am a bit confused about the connection, whether their is 2 connections going to power supply, one from the control box and one from the VFD. I am from the Caribbean and this is first machine on the island so there is no machine nearby for me to have a look at.
