2. Operating Instruction：
(1). Make sure the input voltage is 100V~240VAC。
(2). Make sure LED Indicator is in stand-by mode: (Green Lights up constantly)。
(3). Make sure if 12V * 2 pcs Lead-Acid battery (50AH is standard or follow supplier’s proposal)
(4). Batteries should be placed levelly as the Picture, and avoid a big angle slope or upside down placing.
(5). Make sure the output plug of charger connecting to batteries’compactly.
3. LED Indicator Description：
Green Orange Status description Max Range
Stand-by model Until battery connected the charger
In charging
Over Temperature Protection
Max charging time depends on the Battery
capacity
Until temperature return to normal
Full charged Until battery disconnected the charger
Charging-inhibition Until battery disconnected the charger
:LEDoff :Ledblink(1Sec)
4. Troubles Shooting：
(1). If no stand-by（Green）light indicates：
•Make sure the AC power source is normal, and plug in the charger。
(2). If no charging（Orange）light indicates：
•To check Battery polarities are connected correctly and the connection of Plug is compactly.
(3). If charging-inhibition（Orange）light is blinking：
•To obviate the status as protection specification, maybe batteries are damaged or out of life.
5. Caution：
(1). Avoid charging in a high-temperature or hermetical environment, over 45℃.
(2). If any cracking of Battery housing, please do not use it.( charge or discharge )
(3). Do not expose Charger to water, wet, dusty environment or close to inflammable stuff.
