3.2.2 Heating rod selection
Output interface: heating load power is no more than 230V/4000W, resistance value isn’t less than 13 ohms.
Wall mount installation
NOTE: Wall-mounted installation is important! The wall or mounting frame on which the controller is installed must be able to bear the weight of the
controller to prevent personal injury and machine damage caused by the controller falling o!
The controller is required to be perpendicular to the mounting surface, If the installation angle deviates from the vertical direction by more than
45 degrees, it will cause poor heat dissipation of the controller, which may aect the power output of the controller.
3.2.3 Wall mounted installation
Choose any set of mounting holes, and install the controller vertically on the wall with expansion screws.
3.2.4 Remove the wiring cover
WARNING! Electric DANGER!
Before removing the wiring cover, please make sure that the controller is disconnected from all power sources, and let the controller stand for
more than 5 minutes to ensure that the residual power inside the controller is discharged to a safe level. Any live operation will put the operator
in a dangerous situation and may cause damage to the controller.
Remove the wiring cover as shown in the gure below.
3.2.5 Power cord connection
WARNING! Risk of electric shock!
The maximum open circuit voltage of the solar panel array should not exceed the maximum value of 350VDC specied by the controller.
Before installation, make sure that the solar panel and the cable are disconnected.
Follow the steps below to connect the terminals shown in the gure above:
● Before wiring, make sure that all the breakers are connected to the controller are in the o status.
● There is no breaker inside the controller.
WARNING! Note that the positive and negative poles of the solar panel cannot be reversed!
WARNING! Note that it must be ensured that the ground is wired correctly !
WARNING! Note that if you choose a heating load that exceeds the rated power, the controller will be damaged!
