Please comply with all warnings and operating
instructions in this manual strictly. Save this
manual properly and read carefully the following
instructions before installing the unit. Do not
operate this unit before reading through all
safety information and operating instructions
carefully.
When Using battery
Danger of High Voltage：
The high voltage power supply offer the equipment power, wet object contact high voltage power
supply directly or indirectly , can cause fatal danger.
Using a special tool :
Working in high voltage and ac power, be sure to use a special tool instead of individual tools.
1.Safety Precaution

4
Static‐free：
Static electricity would damage veneer on the electrostatic sensitive components, before touching the
plug‐in, circuit board or chips, be sure to use correct electrostatic prevention measures.
Disconnect the power supply in operation:
When operate the power supply, you must first cut off power supply, power operation is prohibited.
Dc short circuit dangerous：
Power system provides dc regulated power supply. Dc short circuit could cause fatal damage to the
equipment.
While Charging
CAUTION：
The temperature range over which the battery can be charged is 0°C to 45°C. Charging the battery at
temperatures outside of this range may cause the battery to become hot or to break. Charging the
battery outside of this temperature range may also harm the performance of the battery or reduce the
battery’s life expectancy.
When Discharging the Battery
DANGER：
Do not discharge the battery using any device except for the specified device. When the battery is used
in devices aside from the specified device it may damage the performance of the battery or reduce its
life expectancy, and if the device causes an abnormal current to flow, it may cause the battery to
become hot and cause serious injury.
CAUTION：
The temperature range over which the battery can be discharged is -20°C to 60°C. Use of the battery
outside of this temperature range may damage the performance of the battery or may reduce its life
expectancy.
