I'm trying to power an Arduino project via AC using meanwell AC/DC supply IRM-20-12

I've taken the device from meanwell_irm_v7.lbr

When I connect the PSU to my Arduino Pro Mini, Eagle CAD is reporting Output and Supply PINS mixed. I've seen similar questions and replies indicating that the device in incorrect and should use pwr pins. I'd be surprised that the library is at v7 with this sort of error. Am I connecting it up wrong? See attached pdf (for some reason I can't attach a sch file - this is my first post)

Can someone help?

You can check the power supply for the correct polarity easy enough.

finding errors in the Eagle libraries is a common event, common enough

that I won't use a component until I've verified the pinouts from a

data sheet or the actual part.  Once corrected, I put the part in my

custom library, 00john.lbr.  The zeros make the library appear as the

first one in the sort.

Apart from Neons answer: Help pin.

Further down you find explanations about the directions on pins.

For the ERC to work the direction of pins must be given correctly.

Supply pins of devices (Vcc, Vdd, GND) are set as PWR because they are

"Inputs for power".

Devices which "give" power (like a battery) have direction SUP

Make the directions visible by activating the layer "PINS" in *.sch.
