Three Installation Instruction
3.1 Notes
1. Read the entire installation section and familiarize yourself with the installation steps
before installing。
2. Be very careful when installing the battery. Wear protective glasses for the installation
of lead-acid battery with openings。
3. Avoid placing metal objects near the battery to prevent short circuit of the battery。
4. The battery may produce acidic gas when charging, ensuring good ventilation around
the environment。
5. Please install indoors and outdoors to avoid direct sunlight and rain infiltration。
6. Phantom connections and corroded wires can cause excessive heat to melt the
insulation layer, ignite surrounding materials, and even cause a fire. Therefore, it is
important to ensure that the connectors are tightened and the wires are secured with a
binding band to avoid loose connections caused by the shaking of the wires when
moving applications。
7. The battery pack installed should match the charging voltage of the controller and the
recommended range of charging current。

space!Do not install in a confined space where battery gas can accumulate。
3.2 Installation
Step 1：choose installation place
Avoid installing JND-X controller in direct sunlight, high temperature and water prone places,
and ensure good ventilation around the controller。
Step 2：Unpacking and checking
(1)Check packing for breakage or deformation；
(2)Unpacking checking: one controller, one manual, one attachment, etc；
(3)Check appearance and accessories of the host are in good condition；
The above abnormal conditions, please contact the company。
Step 3: fixed controller
First, install the lug accessories to the reserved installation positions on both sides of
the top of the housing. Fix the controller to the installation platform or space bracket through
the lug with M5 screws (recommended). Reserve enough ventilation and heat dissipation
space around the installation。

3.3 Connect wires
Note：for installation safety, we recommend a wiring sequence；
Note：JND-X designed with a common negative electrode；
Warning：Do not connect the load end to the electrical equipment that exceeds the
surge power of the controller to prevent damage to the controller!
Warning: make sure all wires are fixed when you need to move them around. Virtual
connections can cause heat buildup, which can lead to fire
Step 1：first disconnect the controller switch(default before leaving factory is disconnect）
Step 2：connect battery
Check battery is in normal state，install as 3-2 showing，during the process, please
disconnect the air switch for wiring。
Warning：All switches must be disconnected in the process of wiring, pay attention
to the difference between positive and negative wires;The metal part of the cable terminal
should not be exposed too long to prevent short circuit fault caused by contact with the
housing after installation.
It is strictly forbidden to connect the battery with positive and negative conductor short
circuit, and it is strictly forbidden to connect the photovoltaic array to the battery terminal
post, please be careful to operate.
Step 3：connect PV, battery, loads

Note：Monitoring background supports PC upper computer, WIFI module and GPRS
module expansion to achieve APP cloud monitoring (optional), see PC upper computer and
APP operation manual for details；
Step 4：check connection
Check all wiring polarities are correct and terminals are locked；
Note：PV 1 is the main road, and pv 2 is the auxiliary road. PV 1 must be connected
to PV array first；
Step 5：Current order
Power on: turn off the battery switch, controller switch, photovoltaic switch (first
photovoltaic 1, then photovoltaic 2), load switch (please operate in strict accordance with
this order)；
After the battery and controller switch is turned on, the controller will start, and the
display screen and LED indicator will work. Please pay attention to the above information. If
the controller is not started, or the display screen and indicator on the controller are warning,
please stop the photovoltaic and load switch closing operation, refer to chapter 5 for
troubleshooting.Turn off the photovoltaic switch before turning off other switches。
Warning：Please switch on the power in strict accordance with step 5, otherwise
there will be the risk of burning down the controller。
3.4 Photovoltaic array requirements
Warning：1、Electric shock danger!Photovoltaic modules can generate high
voltages, so be careful not to shock when wiring.Please ensure that the solar panel voltage
in the system does not exceed the maximum input voltage range of the controller。
