Remove the two screws on the controller, and then begin the wiring operation. In order to
guarantee installation safety, we recommend the following wiring order; however, you can
choose not to follow this order and no damage will be incurred to the controller.
1.
Connecting to external temperature sampling interface.
2.
Connecting communication cable.
3.
Connecting power cable.
WARNING! RISK OF ELECTRIC SHOCK!
We strongly recommend that fuses or breakers be
connected at the photovoltaic array side, load side and battery side so as to avoid electric
shock during wiring operation or faulty operations, and make sure the fuses and breakers
are in open state before wiring.
WARNING! DANGER OF HIGH VOLTAGE!
Photovoltaic arrays may product a very high open-
circuit voltage. Open the breaker or fuse before wiring, and be very careful during the wiring
process.
WARNING! RISK OF EXPLOSION!
Once the battery’s positive and negative terminals
or leads that connect to the two terminals get short-circuited, a fire or explosion will occur.
Always be careful in operation. First connect the battery, then the load, and finally the solar
panel. When wiring, follow the order of first ‘+’ and then ‘
-
‘.

Power on. After connecting all power wires solidly and reliably, check whether wiring is
correct and if the positive and negative poles are reversely connected. After confirming that
no faults exist, first close the fuse or breaker of the battery, then see whether the LED
indicators light up and the LCD screen displays information. If the LCD screen fails to display
information, open the fuse breaker immediately and recheck if all connections are correctly
done. If the battery functions normally, connect the solar panel. If sunlight is intense
