70).Installation Instructions

  • Controller Fixed

1)The controller should be installed well-ventilated place,

avoid direct sunlight,high temperature and do not

Install in location where water can enter the controller.

2)Please select correct screw to fix the controller on the

wall or other platform. Screw M4 or M5,Screw cap

diameter less than 10mm.

3)Please reserve enough space between the wall and

controller,to allow for cooling and cable connection.

4)The mounting holes distance is 155.8mm*63mm,

diameter of the hole is 5mm.

The suggestion of using

  • The controller could detect the temperature of environment to adjust the voltage of charging, so that the controller should be closed to battery as near as possible.
  • Recommend system current density of cables less than 3A/mm㎡ .
  • Try to use the multi strand copper wire in order to connecting with the terminal firmly. Loose power connection and/or corroded wires may result in resistive connections that melt the wires insulation, burn surrounding materials or even cause fire.
  • The battery should be full charged each month. Or the battery will be destroyed.
