Protection Features
1.Thermal Self-Protection: When the internal temperature of the charger exceeds 80℃, the charging current will reduce automatically. If exceeds 85℃, the charger will shutdown protectively, there is no current output in this case. When the internal temperature drops to 80℃, it will resume charging automatically.
2. Short-circuit Protection: when the charger encounters unexpected short circuit across the output, charging will automatically stop. By cutting AC power for 10 seconds, the charger can be re-set and will start normally(with the output circuit corrected)
3. High and Low Voltage Protection: when the input AC Voltage is higher or lower than the rated input voltage range, the charger will shutdown protectively, but resume working after the voltage is normal again.
Inter-lock Function
When it discharges, the internal electrical relay connects the blue and red wire, and outputs battery voltage. During the charging, the blue wire disconnects the internal connection, and no voltage outputs.
Note: Do not let the current on green wire flow over 2A
Choice of Charging Curve (curve 1~10)
1. The LED will flash red several times when AC is first connected, then
the LED will flash green once. The number of red flashes denotes the present curve. E.g. If the red flashes three times, it means the present curve is curve 3.
2. To choose another curve, please cut off the power supply first, then unpeel the
label, pressing the button while connecting the power. If you want to choose curve 3, release the button after the 3rd LED Flash. Now the selected curve (e.g. curve 3) will be recorded in memory. If you want the charger to work with the selected curve (e.g. curve 3), cut off the power and reconnect it.

Installation & Safety Instructions
Our charger has been designed to provide safety and reliability. It is important to observe the following precautions and installation instructions in order to avoid damage to persons and to the battery charger. For further reference keep the instruction in a proper place.
1. Fix the battery charger to a stable surface with the holes inserted on the mounting tabs. In case of installation on a vehicle, it is advisable to use anti-vibration supports.
 |
2. Preferably the charger should be installed in the vertical position with radiator fins vertical. A space of 10cm above ground should be vacated, to ensure it is ventilated. Never install in the vertical position with fins facing down. Refer to drawing below:
3. Ensure all heat dissipating parts are not obstructed to avoid overheating. Do not put the battery charger near any heat sources. Make sure that free space around the battery charger is sufficient to provide adequate ventilation and easy access to cable sockets.
4. For safety and electromagnetic compatibility the battery charger has a 3-prong plug that will only plug into a proper grounded outlet
5. To avoid damaging the power cord, do not put anything on it or place it where it will be walked on. If the cord becomes damaged or frayed, replace it immediately.
6. If you are using an extension cord or power strip, make sure that the total of the amperes required by all the equipment on the extension is less than the extension’s rating.
7. Verify that the selected charging curve is suitable for the type of battery to be recharged.
8. In order to avoid voltage drop, the output cables must be as short as possible, and the diameter must be adequate for the output current.
9. Do not try to service the battery charger yourself. Opening the cover may expose you to shock or other hazards.
