Re: Battery Connection

Neel,
You need to first consult the robot section of the manual, and the Tips and Guidlines document. There is some great info in both of these. Download them and keep them on your computer, you will need to refer to them often.

The KOP has several crimp terminals for #6 wire and a bag (in the Burndy Bag) of screw clamp lug terminals. Find the clamp type terminals, they are silver in color and have a screw, a collar and a tab with a mounting hole. The bag may say KP4AC on it. You can use a utility knife to remove about 3/8" of the insultaion from the #6 wire attached to the Anderson 50 amp quick disconnect connectors. Don't use a slicing motion when removing the insulation. Simply lay the blade on the wire and gently rock the blade until it meets the wire inside. Repeat until you have a separation around the entire wire. If you gently bend the wire at the cut you should see the bare wire inside. Lay the wire down on the workbench and place your knife parallel to the wire and pointing towards the cut end of the wire. Gently push the blade of your knife parallel to the wire until you cut through the insulation. This will allow you to remove the insulation. Insert the stripped wire into the open terminal opposite the tab and between the clamp and the tab. The wire should not be touching the screw. See attached picture. Tighten the screw to clamp the wire. You can complete the connection with solder if you wish. Heat up the collar of the clamp until solder melts and starts to flow when placed at tab end of the terminal. Only allow enough solder to flow to wet the wire and the terminal but not so much that you see solder flowing under the wire insulation. When cool, insulate with heatshrink tubing or electrical tape. When you attach to the battery, I use an external tooth star washer between the KP4 tab and the battery terminal. When you tighten the mounting hardware, the star washer prevents the two terminals from moving against eah other. Insulate with elctrical tape or heatshrink so that no metal is exposed.
Referring to the electrical wiring diagram, connect the other end as shown to the Rockwell block and 120 amp circuit breaker. Then connect the other breaker panels as needed using the diagram as a guide.
A rule of thumb for wiring is to make everything only as long as absolutely needed. We trim the wiring for the battery side down to just a few inches. Every inch of wire relates to loss. The more wire you use the less amount of power will be delivered to your motors and the RC.
