50 amp connection to a Victron Multiplus 12/3000/120-50 120V

I purchased a Victron Multiplus 12/3000/120-50 120V and I am planning to install it in my Columbus 5th wheel with 50 amp shore power hook up, my question is with two conductors a neutral and a ground, how do I hook up the AC in?. Do I connect one conductor to the multi plus then use the AC out to one half of the breaker panel and the other conductor directly to the other half?.

Also, can I connect the Multi plus into the shore power without having any batteries connected? will the multi plus just allow the power to just pass through or will it damage the unit?

Welcome to the wonderful world of US 120/240V 50A Split Phase power. Yes, use either the L1 (black) or L2 (Red) and the Neutral and the ground to connect to AC In. The AC out is a little more complicated. You can really screw things up if you get it wrong.

Best advice I can give is that you contact a Victron installer in your area and let him advise you. There are life safety issues involved.
