For installation safety, we recommend a wiring sequence as follows; however, wiring in other sequence instead of this one
will not damage the controller.
1) Note that the battery fuse shall be installed as close as possible to the battery terminal. The
Note
recommended distance is not more than 150mm.
2) The battery temperature is 25°C (fixed value) when the controller is not collected to a remote temperature
sensor.
