Determination of installation location: The controller shall be installed in a place with
sufficient air flow through the radiators of the controller and a minimum clearance of
150 mm from the upper and lower edges of the controller to ensure natural thermal
convection. Please see Figure 2-1: Mounting
CAUTION: If the controller is to be installed in an enclosed box, it is
important to ensure reliable heat dissipation through the box.
Step 2：Connect the system in the order of ❶battery ❷ load ❸PV array in

the reverse order❸❷❶.
CAUTION: While wiring the controller do not close the circuit breaker or
fuse and make sure that the leads of "+" and "-" poles are connected
correctly.
CAUTION: A fuse which current is 1.25 to 2 times the rated current of the
controller, must be installed on the battery side with a distance from the
battery not greater than 150 mm.
CAUTION: If the controller is to be used in an area with frequent lightning
strikes or unattended area, it must install an external surge arrester.
CAUTION: If an inverter is to be connected to the system, connect the
