MOUNTING THE CIRCUIT BOX
The circuit box can be mounted using any of the following methods: Two round-head screws, industrial
adhesive, heavy-duty dual lock or double-sided tape (not included).
1. After cleaning the install area, place the box close to the battery so that the lugs can reach the
terminals. DO NOT attach it to the battery itself. Also make sure the box is located in a location
where it won’t be disturbed.
2. If needed, use plastic cable ties (not included) to secure the circuit box wires to the battery cable
or other secure area near the battery. This will keep the wires from being damaged or
interfering with any moving engine parts.
3. LED: The circuit box includes an LED on top. The LED will light after the lugs are attached to the
battery terminals and the solar panel is installed and receiving sunlight.
WARNING: Any solvents that may be harmful to plastic should not be used on or near the unit.
CONNECTING THE LUGS
Important: The positive (+) red wire MUST be connected to the positive (+) battery terminal and the
negative (-) black wire to the negative (-) battery terminal in order for the unit to work.
1. Connect the positive red wire first. After removing the nut from the bolt securing the battery
clamp to the positive battery terminal, slip the round metal lug at the end of the positive red
wire onto the bolt until it sits next to the clamp.
2. Slip a round washer (not included) on to the bolt until it sits next to the lug.
3. Replace the nut onto the bolt and tighten it until it secures the lug and washer against the
clamp. Do not over tighten.
Repeat 1-3 above to connect the negative black wire to the negative battery terminal.
WARNING: Do not hold the positive and negative lugs at the same time while the unit is active (receiving
sunlight). It may cause a slight electric shock.
MOUNTING THE SOLAR PANEL
The solar panel can be mounted using any of the following methods: Four round-head screws, industrial
adhesive, heavy-duty dual lock or double-sided tape (not included).
1. Mount the solar panel where it will have direct access to sunlight. It can be mounted
horizontally or vertically.
