So for future reference for anyone looking at this thread, here's my "it works!" post:

Here's the wiring diagram for US users:


I carefully wired everything up with a Nema 10-30 plug, typically sold for use as a three-prong clothes dryer replacement cable.

Double, triple, quadruple check proper continuity and wiring with a multimeter.

Shorted the 3 pins with an extra servo cable in order for the unit to turn on

Installed bullets on the DC output pins. Female EC5s wedge in between the PS blades/pins perfectly. Just cover the outside of the EC5 and the inner side of the PS pins with flux, stick in the EC5, and hold the tip of the soldering iron against the part where the bullet and pin meet, and melt solder all around. (I should have used this method for the AC pins too instead of trying to tin everything separately. Learn from my mistake.)

Turned off the dryer breaker, plugged in the power supply, flipped breaker on. Fans spooled up without an explosion! Fantastic!

Used the multimeter on AC setting to ensure I wouldn't get shocked by the metal case (since there's no real ground, only a neutral). Just touch one prong on the chassis of the PS and the other prong to a known ground. I used the center screw of a nearby AC outlet (confirmed ground by first testing with the 110v outlet). Safe to touch! Great!

Confirmed the DC power output was working, albeit a little high for the iCharger.

Then proceeded to follow the rest of steps from the original post by installing the resistor (tricky to find because it's covered with gray rubbery goo). I went with a 2k2 ohm resistor. I actually found this step pretty easy. Soldering PCBs just requires a quick touch of the soldering iron and since there was already solder on the board left over from the removal of the voltage adjustment potentiometer, it makes for quick work.

Retested everything with the multimeter, confirmed my DC output is under 50v (mine is at 48.5) and connected my charger.

I'm now charging my first set of batteries on my brand new iCharger 4010 Duo!
