Installation
1. Connect the accessories such as the temperature sensor. The 2-pin connector of the temperature
sensor cable connects to the temperature sensor port on the charger. Connect the other end with
an eyelet terminal to the battery negative terminal to measure the battery temperature.
2. Remove terminal cover before installing wires.
3. Connect the load cables (if applicable) to the charger matching the polarity as indicated by the
symbols on the charger. To avoid tension in the cables, connect the cables to the load first and
then connect them to the charge controller.
4. Connect the battery cables to the charger matching the polarity as indicated by the symbols on
the charger. Make sure a properly rated fuse is installed in line on the cable for the positive lead of
the battery.
5. Connect the PV array cables to the charger matching the polarity as indicated by the symbols on
the charger.
Note: Solar panels produce voltage and current whenever they are exposed to light. When
connected in a circuit, the amount of current produced by the solar panels is directly proportional
to the light intensity. Be careful when connecting the PV array cables to the charger terminals.
The connection of a properly rated fuse is optional but they add additional system safety. A
disconnect switch can be very convenient if need arises to disconnect the solar array to the
charger for maintenance and troubleshooting.
6. Add back terminal cover. Ensure wires or terminals are not exposed after installation.
7. Connect an 8AWG cable with a crimped eyelet terminal to the ground lug on the charge
controller and connect the other end to the chassis grounding point.
8. Make sure all the cables are securely attached to the charger terminals. If a disconnect switch is
present in line between the solar array and the charger, turn it on to supply power to the charge
controller.
Note: Install the provided rubber plugs on top of the wire terminal screws to avoid accidental
contact with the high voltage connections. Use insulated tools to remove them if needed.
9. Observe the operational indications like the LEDs, icons on LCD screen or the parameters on the
Bluetooth app for further information.
Grounding
The 40A and the 60A charge controllers are equipped with
an M6 size ground lug on the side of the heat sink. It is
recommended to use an 8AWG conductor with an eyelet
terminal for grounding the controller to the vehicle chassis in
case grounding is required.
CAUTION: For common-negative system, such as
motorhome, it is recommended to use a common
negative-type controller.
