Progressive Dynamics charger PD4045
I am trying to wire up PD4045 "Mighty Mini" in a 10' utility trailer/workshop. I have the AC side figured out. On the 12 V side....there are 12 wires coming off the fuse bar. 2 red are for 30 amp...

The power center's ground bus should be bonded to the vehicle chassis directly. From what pictures I can see online, I think PD intended this to be done via the mounting screw adjacent to the ground bus bar, which goes through a little angle iron thingy on the back side that also connects to the ground bus bar. If it's not being bolted to some metal framework in the trailer, a ground strap or wire of some sort should be run (probably to a terminal on the bus bar) to bond the AC ground to the trailer chassis.
Note that the safety ground from the power center should go directly to the vehicle chassis, not to the battery negative terminal. It needs to be properly bonded even if the battery is removed or disconnected. There's no need to connect the AC ground to the battery directly in any way. (For that matter, the DC negative connection of the power center doesn't need to connect directly to the battery, either; it can go to a good chassis ground, leaving just one connection at the battery negative, that to the chassis.)
