Connect the battery to the charge regulator-plus and minus. 2. Connect the photovoltaic module to the regulator-plus and minus. 3. Connect the consumer to the regulator-plus and minus. NOTE: The reverse order applies when deinstalling, an improper sequence order can damage the controller. Safety Instructions: 1. Make sure your battery has enough voltage for the controller to recognize the battery type before first installation. 2. The battery cable should be as short as possible to minimize loss. 3. The regulator is only suitable for lead acid batteries: OPEN,AGM,GEL, it is not suited for nickel metal hydride, lithium ions or other batteries. 4. The charge regulator is only suitable for regulating solar modules. Never connect another charging source to the charge regulator. Notice: 1. Please allow slight deviation of measurement due to manual measurement. 2. Due to different producing batches, product details might be a little different.
