Need help regarding isolator wiring configuration.

Hello everyone. I just bought and received a Topaz Ultra Isolator. Am I wrong in thinking so or is it already wired for balanced power? It looks odd in both the configuration and using both brown and red wiring jackets (which from what I understand usually are both used for hot wires), and the jumper from the third terminal to the second is odd to me. I'm not really educated enough in this matter to know what's going on here and there's not really a detailed wiring configuration like one seen on other models, only a single picture on the side that I've included.

The unit's input is a 6-20r input plug which needs to be replaced with a 20 amp iec inlet (due to the plugs being reversed on the 6-20r I have no idea if the hot and neutral wiring would be reversed as well compared to a usual 20 amp plug, but I'm assuming not?), and I wish to replace the outlets as well, but I want to make sure of everything before tackling this.
