5.1 Installation Notes
Batteries can produce flammable gases. Avoid making sparks, using fire or any naked
flame. Make sure that the battery room is ventilated.
Avoid touching or short circuiting wires or terminals. Be aware that the voltages on
special terminals or wires can be as much as twice the battery voltage. Use isolated tools,
stand on dry ground, and keep your hands dry.
Prevent water from entering the internal controller, outdoor installation should avoid
direct sunlight and rain penetration.
(1)Do not open the controller sheet metal case, only the terminal cover may be removed by
a technical professional for installation.
(2)Before wiring installation and adjustment of controller, Always disconnect the solar
modules and insurance or circuit breaker of battery terminal.
(3)Only to comply with the range of the battery charge controller.
(4)Batteries store a large amount of energy, never short circuit a battery under all
circumstances. We strongly recommend connecting a fuse directly to the battery to avoid any
short circuit at the battery wiring.
(5)
(6)Uses insulated tools and avoid placing metal objects near the batteries.
(7)Be very careful when working with batteries. Wear eye protection. Have fresh water
available to wash and clean any contact with battery acid.

(10)After installation check that all connections are tight line, avoid heat accumulation
caused by virtual access danger.
(11)Multiple same models of controllers can be installed in parallel on the same battery bank
to achieve higher charging current. Each controller must have its own solar module(s).
(12)Select the system cables according to 5A/mm² or less current density.
Please read all instructions and precautions in the manual before installing.
It is recommended to remove the acrylic protective film covering the LCD
screen before installation.
5.2 Battery cables and battery fuse
Cable strain relief must be provided, close to battery and PV connectors.
In order to utilize the full capacity of the product, battery cables with sufficient cross section
and a fuse of sufficient current rating should be used.
!
2.Please consult local regulations regarding maximum allowed current carrying capacity
of cables.
