Those are correct. I just pulled the cover off my
(working) 1000 M-Series
that has a later model supply (5061-6630 date code 2601) but has the same
motherboard as yours (5061-1371). J1, J2, and J5 are as above --
Preregulator (5061-3457), Inverter (5061-3454), and Control (5061-6627). I
have the power fail option, so J3 is the Battery Charge card (5061-1348)
and J4 is the Battery Backup card (5061-1349).
Ok, thanks! I just tried mine again, it's a dud so I am going to have to
figure it out. First step was to see if the rectifier had any voltage so
I disconnected the + side and checked it with a voltmeter. With 120v
plugged in I saw 200v DC which is probably not too far off. That seems
to go to the inverter card, which I don't know what it's doing with that.
Is there a block schematic of what does what on this PS?
