A:Answer There are instructions in the manual. There's a plate on the back above that hole. You remove that to get access to several screws. The non-plug end of the cable has little rings or maybe u-shaped connectors that go under the screws. Mine was a 3 wire install. In that case, you just hook the left and right connectors to the left and right screws, and the middle one goes in the middle. Left and right are interchangeable, so you don't have to worry about whether the cable is flipped around.
In my case, the cable had rings for connectors, so that meant removing each of the connector screws. Easiest to take all three out, then screw them back in one at a time.
NOTE: the cable should have a clamp with it. You want to put that in the hole--on the outside--and push the cable end through it and up toward the connector screws.
For me, the sequence that worked nicely was:
After removing the access plate...
1. Remove the connector screws
2. Put the cable clamp in place in the hole, but loose
3. Push the cable end through it and upward
4. Screw the connectors down
5. Tighten the clamp down
Screw the plate back on. It has to lie flat before you screw it down, so you have to fiddle with it a little. It goes in a little high then slides down in a small slot. If you have it right, it sits there nice and flat without holding it, and driving the screw back in is easy.
Plug the plug into the outlet etc.
The manual is very important for this part of the install. Wish I'd thought to take photos. Too late now.
