Step 2Prepare for Wiring
The first step it to get power to your inverters. Use caution as you will be working with electricity although you should just be dealing with low voltage. Safety first!
See Step 1 for information selecting parts.
1. Power Supply
Point A in Figure:
With the 12V DC power supply unplugged, prepare it by cutting off the small DC connector on the output. If you're extra handy with things and have a jack/plug that fits the 12V connector, you could solder in a connector like I did so you could replace the power supply easily. I found the connector on an old set of computer speakers. Separate the two wires of the output and use a multi meter to check which wire is positive and which is ground. Mark this wire for later and unplug the power supply.
NOTE: If installing this in a camper or place where 12V DC is already available, you can skip the power supply. DEFINITELY use an inline fuse in this situation though to protect your power source and wiring.
2. Fuse (optional but recommended)
If you are installing an inline fuse, connect it inline on the positive DC wire, near the power supply. It is best to put this close to the power supply before the switch for the most safety. This is useful if you get a short so wires don't melt or catch on fire. Most power supplies include a fuse in them but an extra one won't hurt and it may also save your power supply from damage. Choose a fuse slightly higher than the maximum current you expect your setup to use.
3. Switch (optional but recommended)
A switch is useful if you want to be able to easily turn the under-cabinet lighting on and off. I used a lamp switch a friend had. Make sure it is rated appropriately. If your power outlet is on a switch you can just use that instead. You can also just plug and unplug the power supply but you probably don't want to do that all the time as things may wear out and it would be inconvenient.
4. Inverter
Point B in Figure:
Cut off any cabling, switches, and plugs going to your inverter's INPUT, noting which cable is black or connected to the black wire. This is your ground. Do NOT cut off the cables going from the inverter to the lamps.
