Hi, I am not quite sure of what kind of set-up you are saying you have when you say it says line ground natural? If you have a 115/230 volt power supply, this should be very easy to tie into. Look at the wiring diagram on the new unit real good and locate the 2- hot wires that should say line one or L-! and L-2. Your 230 volt wires will connect one to each side of those 2 connections, and will have a ground wire that grounds to a metal lug or screw on the unit. Look over the diagram for field wiring connections for high voltage and this will tell you where you need to hook your 230 volt wires and ground to. If this new unit is 208/230 volts, you should have connections like I have said either L-1 or t-1 and L-2 or T-2 that you will tie in your 230 volts to. Just look over the diagram and you will see where the beginning of the 2 hot wires come into the unit. There should be either 2 good sized black hot wires that are for your incoming hot wires to connect to, or they are already connected to the contactor, and you will need to connect yours to the line side of the contactor. I see what you are saying now, that they are only showing you 1- 115 volt connection to the new unit so you will have only 115 volts to run it. You want to know where the other 115 volt conductor hooks up for 230 volts. This is why you need to look at the schematic and wiring diagram that shows both of the 208/230 volt connections on this new unit so you can connect both hot wires to it. I can't pull up a picture of this on the Internet, but it will show you on the schematic on where they connect. This line ground neutral connection sounds as though its not for a hot wire, but for your ground, or if you happen to have a neutral wire that is being used for a ground. Please keep looking for the 2- line in connections as this is what you will need to find and where both 115 volt wires connect. They are your line voltage wires, so they need to connect to the load voltage hot wires at the L-1 and L-2 connections of this unit. This should be fairly laid out for you, but sounds like they have made it difficult? Look for what I have said and the schematic drawing and you will find the connections. Please don't forget to rate me as I know you will be kind. I will be checking back with you as I keep all of your information on file so I can look you back up if I need to. You can contact me by my user name below if you need me also. I wish you the best and follow my instructions and I know you will get it right.
Sincerely,
