Step 1: Determination of Installation Location and Heat-dissipation Space
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.

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.
