Help with wiring a plug

[TravisW]

Hi guys,
I am an Electromechanical Engineering student interning for a company and I have a question regarding the wording in the image attached. My understanding is that "+28 VDC RTN" is what gets attached to the negative terminal of my power source and "ground" will just get attached to the outer casing of the plug itself. I have just never seen the "RTN" terminology used before so I wanted to clarify.
Thanks

Yeah, it is the ground for that power supply (well, it's the negative rail -- I'm assuming it's ground, but it might not be)

RTN is just short for Return
