2: Installation Instructions
Installation
（
Installing wires, first loosen the screw counterclockwise
）
1
Ready Qi installation tools and materials, and cable. Please matching
suitable cable
2
ensure that the current density <4A/mm2 This will help reduce the line
pressure drop.
Check the installation site meets the relevant safety requirements, avoid
damp, dusty, flammable, explosive and corrosive gases
3
Install the controller fixed to the vertical plane, see Section V mounting aperture and hole spacing.
In order to ensure a good controller cooling conditions, the controller on the bottom of each
reserved 10cm space
4
As shown on the right wiring sequence: load, battery, solar
Battery plate is connected to the controller to be taken to ensure that the load, battery,
The polarity of the solar cell panel and controller
5
Before use: external temperature sensor probe into the left of the controller temperature probe
interface probe placed in similar battery temperature. (Line extension must be built-in devices of
the external temperature probe coextensive Otherwise, the controller will control parameters of the
temperature compensation of the error
6
Warning: In order to prevent accidents from occurring, install: non-professionals can not be
engaged in loading and unloading operations
