Building Instructions

Step 1

Unscrew the black, ribbed collar at the bottom of the e-stop button. Once this comes off, remove the metal plate at the bottom of the button as well.

Step 2

To place the button through the contact block, make sure that the red switch on the contact block is in the leftmost position.

Step 3

Put the bottom end of the button through the hole in the enclosure. Replace the metal plate on the inside of the enclosure and screw it into place with the black collar, as shown in the image below.

Step 4

Attach the contact block and turn the block’s red switch to the rightmost side in order to lock the button into place. The final assembly should look like the picture below.

Step 5

Drill holes into the black bottom half of the controller, as shown in the image.

  • NOTE: - Use a 1/4" drill bit to pre-drill a smaller hole to prevent the plastic from splitting, and then make it bigger using a 5/16” drill bit.

Step 6

Now it is time to connect the power cable wires to the female barrel jack adapter. After separating the black and red wires, cut a few inches of the red wire off (this is how you will connect the positive wire across the switch).

Step 7

The switch infrastructure uses ring terminals. Thus, strip about 3/8” of one end of the red wire and use a crimping tool to attach a red ring terminal to the stripped end. In the same way, attach a red ring terminal to the red wire still attached to the black wire.

Step 8

Strip about 1/4” of the other end of the red piece of wire and the longer end of the black wire. The barrel jack adapters use screw terminals, so loosen the screws, push the stripped wires inside the corresponding terminals, and tighten the screws. Since screw terminals have the potential to come loose, adding a dab of hot glue to each connection ensures the wires will not slip out.

Step 9

Hot glue the female barrel jack adapter to the bottom of the enclosure so that the smaller end fits through the drilled hole. Next, thread the remaining cable through the other drilled hole.

Step 10

Loosen the screws of the e-stop switch and place the ring terminals inside so that the screws go through the terminals. Then, tighten the screws and ensure that the terminals are not moving at all. After steps 6-10, you should have an e-stop that looks like the picture below.

Step 11

Secure the bottom and top halves of the enclosure using the screws that came with it.

Step 12

Finally, attach the male barrel jack adapter to the exposed end of the power wire cable. Follow the same directions as in step 8. The male barrel jack attachment should look like the following picture.
