Installation steps:
Step1: Determine 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 minimum clearance of 150mm from the
upper and lower edges to ensure natural thermal convection.
CAUTION: Ensure that the controller is able to dissipate heat if it's installed in a closed
area.
Step2: Wiring❶❷❸
Connect the system in the order of❶Starter batteryBATT2 →❷BATT1
in accordance with the above diagram and disconnect the system in the reverse
order❸❷❶.
CAUTION:The BATT1 and BATT2 must be set as same voltage level, and other situations are not supported for the
moment.
CAUTION: Follow the above instruction for wiring. Otherwise, it may cause the BATT2 system voltage identification
error.
CAUTION: While wiring the controller do not
turn on the breaker or fuse and make sure that the
leads of "+" and "-" poles.
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 150mm
CAUTION: If an inverter is to be connected to
the system, connect the inverter directly to the
battery, not to the load side of the controller.
Step3：Grounding❹
DR N series is a common-negative controller, where all the negative terminals of PV array and battery can be grounded
simultaneously, or any one of them will be
grounded. However, according to the practical application, all the negative terminals of PV array and battery 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 the human body due to the electrification of the shell.
CAUTION:For common-negative systems, such as a motorhome, it is recommended to use a common-negative
controller, but if in the common-negative system, some common-negative equipment is used, and the positive electrode is
grounded, the controller may be damaged.
Step4: Connect the remote temperature sensor cable❺
Temperature sensor
Connect the remote temperature sensor cable to the port ❹ and place the other end close to the battery.
(Model:RT-MF58R47K3.81A)
CAUTION: If the remote temperature sensor is not connected to the controller, the default setting for battery
charging or discharging temperature is 25 ℃ without temperature compensation.
