Thanks to all for the input.
Sure enough, my 5245L has "H96" on the back, and there is a little sticker above the AC input that says "50-400 Hz", covering up the chassis stenciling which surely said "50-60 Hz".
There are two solid red wires from one capacitor terminal; one goes to S4 on the back panel (120/240 VAC selector switch) and the other goes to the fan.
Sounds to me like if I don't intend on using this in an airplane, I can eliminate the capacitor and run a single red wire from the fan to S4...agree?
?
