Your power entry module will probably have 0.250” tabs with wires with spade terminals soldered to them, according to that photo. I would not buy that particular module but instead one without the silly wires, then crimp fully insulated (like these) quick disconnect terminals onto the wires from the splitter, after cutting off the plug and carefully stripping the jacket, then the wires. Going further, if there’s any exposed metal anywhere with the potential for any high voltage on it, I would cover it with a physical shield to prevent any accidents from fat fingers poking around with the unit plugged in.

But I’m known for going kind of overboard with high-voltage safety. Here’s something I did for someone else; that’s just the power entry cover and I did another over the power supply terminal block.
