5500 PSU Replacement PT 65-B

[DeliciousBurrito]

Hi, replacing the PSU in an s5500 with a PT 65-B and had a question about this connector. In the old unit this cable was reversed, but it will only seem to fit this way in the new one. Just want to be sure I have it correctly before installing it.

That connector is for the AC line in. The connector on the board may be marked with one pin L and the other pin N. The black wire should be L ine in, the white wire should be N eutral. Plugging it in backwards - it should be OK. JUST BE AWARE ! - if 2 machines are in arms length of each other and the line and neutrals are swapped/backwards from each other - you risk the chance that one chassis will be hot in reference to the other (or anything that is made of metal and connected to the AC outlet )
You can verify if there is a problem with a DVM (meter) check for AC voltage between the 2 devices on any metal surface to see if you read any AC voltage. PM me if you are concerned. Most power supplies are setup for 110/220 VAC and this should not be a problem, just be aware. (220 VAC has 2 hot lines, no neutral. So the supply would be OK hooked up either way)

These days this is not much of a problem anymore, most appliances have the ground lug and household outlets have them too. Most small appliances and power units are isolated so no ground plug, just the 2 wire plugs. Much safer.

Thanks for all the information! It just took more pressure than what I thought to get it to snap I to place. Turned the machine on and everything works fine! Only thing left to do is see if the button lights are burnt out or if there is a setting I need to change. The change button works but that seems to be the only one that lights up.

Has to have credits on the machine for the other buttons to light up
