Yes, the negative terminal is always the ground terminal which is also connected to the case.

Subject: [ap-gto] Mean Well power supply question

A week or two ago, Roland stated that the Mean Well works fine with A-P
mounts. I bought a 15V model, and have a question.

The AC line input ground terminal is connected to the metal case, as it
should be. The + and - DC output terminals are isolated from the case.

The power connector on my AP1200 connects the negative wire to the metal
mount case.

QUESTION: Does the Mean Well power supply work OK with the negative DC
terminal connected to ground (case) through the AP12o00 power cable?

I assume it does, but I'd just like confirmation before I connect it.

Thanks.
