How Many times have you looked at the front of a Fanuc Power supply A06B-6087 and wondered what something is, or been in the process of working on a unit and just couldn’t remember which port is input and which is output? Now you don’t have to wonder.

Some people just don’t have the time to rummage through a 600-700 page manual to find the answers they are looking for, so we decided to put it together for you.

 

Using the image at the top of the page, we will break down each section by number:
