You need a power cord that connects into an outlet. Connect the power cord to the white and black cords. The green wire is for grounding it.

I'm not familiar with proper electrical code, but I think the white wire is usually a neutral/negative, or "return wire". It'll need to be spliced with the other neutral wires coming from your power source. Your black wire is your active/positive, or "supply wire." Of course, this'll need to be spliced into the lead wire coming from the power source. And the green wire is your ground.

If you're going to be splicing directly into a live source, like an attic light, outlet, etc., you should definitely test all of the lead wires first with a voltage reader. Because if someone wired it backwards when your home was being constructed, you wouldn't find out until you wired your fan backwards, powered it up, noticed it wasn't working, and went to touch it. And that's a rough way to have to find out.

If you're not comfortable with matching wires, splicing wires, etc., then you should definitely get someone with experience to wire it for you. If done improperly you could possibly start a fire, or worse, electrocute yourself. I used to install digital audio/video systems in public buildings (conference rooms, auditoriums, schools, churches, etc.) and many times while they were under construction or being renovated. There have been several times that I accidentally grabbed a live wire while at the same time grounding myself to metal rafters. It hurts, really bad. So just be careful if you decide to do it yourself.

120VAC fan will not work with batteries.....you'll let the factory smoke out of the fan.

To wire a cord to it use this.....
Black = Line(hot)
White = Neutral
Green = Ground

DO NOT just twist the wires together and tape them....use wire nuts!!!!
If your not sure which prong on the plug goes where if the wires are not color coded..

The narrow flat blade is HOT
The wide, flat blade is Neutral
The round prong is Ground

you would connect this to an open wire ie. the wires that run to an outlet/light switch

or you can buy one of these and plug it in the wall, 110v 3 wire male plug
