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.
1 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 ind
ividual tools
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 electr
ostatic prevention measures.
Disconnect the power supply in operation:
When operate the power supply, you must first cut off power supply, power operatio

n is prohibited.
DC short circuit dangerous：
Power system provides dc regulated power supply. Dc short circuit could cause fata
l damage to the equipment.
2 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.
3When 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.
