grounded. However, according to the practical application, all the negative terminals
of PV array, battery and load can also be ungrounded, but the grounding terminal on
its shell must be grounded, which may effectively shield the electromagnetic
interference from the outside, and prevent some electric shock to human body due to
the electrification of the shell.
CAUTION: For common-negative system, such as motorhome, it is
recommended to use a common-negative controller; but if in the
common-negative system, some common-positive equipment are used,
and the positive electrode is grounded, the controller may be damaged.
Step 4：Connect accessories
 Connect the remote temperature sensor cable
Temperature Sensor
（Model:RT-MF58R47K3.81A）
Connect the remote temperature sensor cable to the interface ① and place the other
end close to the battery.
CAUTION: If the remote temperature sensor is not connected to the
controller,, the default setting for battery charging or discharging
temperature is 25 ° C without temperature compensation.
 Connect the accessories for RS485 communication
Refer to chaper4 "Control Parameters Setting".
Step 5：Powered on the controller
Closing the battery fuse will switch on the controller. Then check the status of the
battery indicator (the controller is operating normally when the indicator is lit in green).
Close the fuse and circuit breaker of the load and PV array. Then the system will be
operating in the preprogrammed mode.
CAUTION: If the controller is not operating properly or the battery indicator
on the controller shows an abnormality, please refer to 5.2
