Autosampler Node Wiring

Grabbing the white connector, pull the battery connector from the solar charge controller

Disconnect the plugs for the autosampler battery

• Be sure to also disconnect the connector that plugs into the battery port of the sampler

Unscrew conduit and release to open up more space to work with

Unscrew existing wires using 260 / 1.5 x 40 flathead screwdriver

Cut and strip each wire

Use a wire cutter to trim existing wire and remove old copper strands

Strip the 18-gage wire about 1/4"

Cut 20-gage wire approximately 6 inches. Repeat until you have five new wires.

Strip each wire approximately 1/4". Do this on both ends of each wire

On only one side of each wire, crimp on a wire ferrule

Crimp a splice connector to the other end of the wire

• Be sure the color of the connector is lined up the the same color dot on the crimping tool

Place the other end of the splice connector over 18-gage wire. Then crimp to secure the connection

• Here, we connect 18-gage brown to 20-gage green; and the rest to matching colors

Although these wires are in pairs, strip each wire individually, approximately 1/4"

Pull the wires through

Reattach the conduit to provide strain relief and prevent wires from being dragged down

Insert the wires and screw down using 260 / 1.5 x 40 flathead screwdriver until tight

• Hand tight is just right. Be careful not to over-tighten and crush the wire ferrules

The battery connectors go in the fifth and sixth positions from the left

Using a 260/2.5 x 50 flathead screwdriver, insert each wire into the respective position shown

Using velcro, re-secure the relay board to the side of the enclosure

Using velcro, attach the battery to the inside of the enclosure door

• Be sure to clean the surfaces beforehand.
• Be sure the soft side is attached to the enclosure.

In case the wiring of an ultrasonic sensor comes loose, here is the wiring.

First reconnect the batteries.

• Remember to plug in the other connector into the autosampler

Secure solar charge controller to the side of the enclosure using velcro

Plug in the solar panel last
