obstruction.
Warning！
Before all devices are fully connected, be sure to disconnect the photovoltaic array end, battery
end, load end and other open (circuit breaker) or fuse.
Prevent water from entering controller.
Attention！
All electrical installations must comply with local and national electrical installation standards.
To ensure safe operation, proper grounding, proper conductor size and necessary short circuit
protection are required.
The connection cable must choose suitable specification, the connection is firm and the insulation is
good.
Check all wiring connections are tight after installation to avoid the risk of heat accumulation due to
virtual connections.
Dangerous！
Do not open the machine cover when the controller is live！
Dangerous！
Maintenance work shall be carried out by professional maintenance technicians.
The controller needs power off before maintenance. After power off, it can be removed after 5
minutes.

3.Installation instructions
3.1 Installation precautions
(1) Read the entire installation section and familiarize yourself with the installation steps before
installing
(2) Be very careful when installing battery, for installation of open lead-acid battery should wear a
protective lens once in contact with the battery acid, please rinse in time with clean water.

(3) Avoid placing metal objects near the battery to prevent short circuit of the battery.
(4) Battery charging may produce acid gas, ensure good ventilation around the environment
(5) Please install indoors and outdoors to avoid direct sunlight and rain infiltration.
(6) The connection point of virtual connection and the corroded wire may cause great heat to melt the
insulation layer of the wire, ignite the surrounding materials, and even cause fire. Therefore, it is
necessary to ensure that the connecting head is tightened, and the wire is better fixed with the tie
belt, so as to avoid the loose connecting head caused by the shaking of the wire during mobile
application.
(7) The installed battery should match the charging voltage of the controller and the recommended
charging current range.
Danger！
Explosion danger！Never install controller and battery in the same confined space！Do not install in
a confined space where battery gas may accumulate
3.2 Installation instructions
Step 1：Select installation site
Avoid installing controller in direct sunlight, high temperature and water easily, and ensure good
ventilation around the controller.
Step 2：Unpacking and inspection
