Step 2 Unplug the solar panels from the power connection and remove the solar power cable from the hole in the node enclosure.

Step 3 screw the wires of the voltage transformer to a terminal block
• Connect the wires to the terminal block AFTER feeding the wire through the hole in the node enclosure.
• Make sure the wires are connected to the terminal block in the correct order. Observe the solar panel wires to verify which way is correct.

Step 4 Plug the line power terminal block into the pcb board
• At this point you should be done! Close up the node and figure out how to elegantly connect the waterproof transformer casing to the node so that it does not get ripped off. One option might be duct taping the transformer to the top of the node (under the solar panel)
