RJ45 7499211122a connection

[rayhh27]

Hi,

I am intending to use the WE RJ45 7499211122a, however I cannot find any design guideline. My question is there are VC2+ and VC2- on the schematic below. Is it okay if I assume that the VC2+ is the 24V and the VC2- is the ground?
Here is the schematic


Thank you.
