Safety Instructions
IMPORTANT, RETAIN FOR FUTURE REFERENCE: READ CAREFULLY
- Risk of Fire, Explosion and Burns: Working in the vicinity of lead acid batteries is dangerous. Explosive gases can develop during normal battery operation. Ensure there is enough ventilation to release the gases. Do not smoke when in the vicinity of the battery under charge.
- Ensure the red cable is connected to the positive terminal and the black cable is connected to the negative terminal if using clamps to connect to your battery. Connecting to the wrong terminals may damage the unit.
- Check the manufacturer's data for your battery and ensure the maximum voltage of the profile you select does not exceed the recommended maximum charge voltage.
- Confirm that the plugs are tightly connected to avoid excessive heating from a loose connection.
- Be careful not to short-circuit the battery connections. Accidental shorting of the terminals or wiring can result in sparks, causing personal injury or a fire hazard. It is recommended to cover the panel with a soft cloth during installation of the regulator to block all incoming light. This will ensure that no damage is caused to the solar panel or battery if the wires are accidentally short-circuited.
- The battery box should not be used by children or persons with reduced physical, sensory or mental capabilities, or lack of experience and knowledge, unless they are supervised or have been instructed on how to use the appliance by a person responsible for their safety.
- Do not alter or disassemble the battery box under any circumstances. Incorrect handling or reassembly may result in a risk of electric shock or fire and may void the unit warranty.
- This product is designed to operate in ambient temperatures between -10°C and 60°C. Do not operate outside of this temperature range. Do not use this product to charge a frozen battery. Discontinue use if the battery becomes excessively warm.

Function Overview
Using Your Battery Box
Main Power Switch: Turn the main power switch clockwise to the 'ON' position. This connects the battery to the inputs/outputs. The switch must remain ON while the battery box is in use for charging or discharging.
Voltmeter: The voltmeter displays the voltage of the battery used in the battery box. Note: This display should not be used to get an accurate reading of lithium batteries; a shunt is recommended for accurate lithium battery voltage readings.
Diagrams show the Main Power Switch (labeled ON/OFF) and the Voltmeter display (showing '8.8.8.').
