1. SAFETY INSTRUCTIONS Thanks for choosing our product, please read carefully the following user manual and the safety instructions before installing the unit or using the unit! Keep this manual for future reference. CAUTION – The batteries should be match with the voltage and current of this product to operate ...
2. INSTALLATION Unpacking and Inspection Before installation, please inspect the unit. Be sure that nothing inside the package is damaged. You should have received the following items inside of package: Charger Unit Manual Mounting bracket x 2 M5 screws x 3 M10 expansion bolts x 4 U bracket DC cable...
Mounting the Unit WARNING!! Remember that this battery charger is heavy so please be careful when removing it from the package. SUITABLE FOR MOUNTING ON CONCRETE OR OTHER NON-COMBUSTIBLE SURFACE ONLY. 1) Choose mounting location Select an appropriate mounting location. Do not mount the battery charger on flammable construction materials.
AC input power source. This will ensure the unit can be securely disconnected during maintenance and fully protected from over current of AC input. The recommended spec of AC breaker is 100A. WARNING! All wiring must be performed by a qualified personnel.
CAUTION: Important Be sure to connect AC wires with correct polarity. If wires are connected reversely, it may cause utility short-circuited. Battery Connection CAUTION: For safety operation and regulation compliance, it’s requested to install a separate DC over-current protector or disconnect device between battery and battery charger. It may not be requested to have a disconnect device in some applications, however, it’s still requested to have over-current protection installed.

WARNING: Shock Hazard Installation must be performed with care due to high battery voltage in series. CAUTION!! Do not place anything between the flat part of the Battery Charger terminal and the ring terminal. Otherwise, overheating may occur. CAUTION!! Do not apply anti-oxidant substance on the terminals before terminals are connected tightly.
3. OPERATION Power ON/OFF Once the unit has been properly installed and the batteries are connected well, simply press On/Off switch to turn on the unit. Operation and Display Panel The operation and display panel, shown in below chart, is on the front panel of the unit. It includes a LCD display, four touchable function keys and RGB LED Bar, indicating the operating status and input/output power information.
LCD Display The LCD display information will be switched in turns by pressing “ ” “ ” button. The selectable information is switched as the following table in order.
