    Installation Instructions

    Installing wires, first loosen the screw counter clockwise

    • Prepare complete installation tools, materials and cable. Please matching suitable cable.
    • 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
    • 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
    • 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.
    • Warning: to prevent accidents (high pressure or high temperature), non professionals can not engage in loading and unloading operations.
    • Be very careful when installing the batteries, especially flooded lead-acid battery. Please wear eye protection, and have fresh water available to wash and clean any contact with battery acid.
    • Keep the battery away from any metal objects, which may cause short circuit of the battery.
    • The controller requires at least 150mm to 300mm of clearance above and below for proper air flow, ventilation heat dissipation fan is highly recommended if mounted in a sealed enclosure.
