MW 12V DC power supply question

[Steveareno]

I have an MW (Mean Well) 120 Volt input power supply with a 12 Volt DC output. Its model number is LPV-60-12. It has brown and blue wires on the input side. My question is: Which wire is the positive wire and which wire is the negative wire?

Please help me.

Thank you,

Steveareno
