Important Safeguards and Warnings
This chapter describes the contents covering proper handling of the access controller, hazard
prevention, and prevention of property damage. Read these contents carefully before using the
access controller, comply with them when using, and keep them well for future reference.
Operation Requirement
 Do not expose the access controller to direct sunlight or heat source.
 Do not install the access controller in a humid or dusty area.
 Install the access controller horizontally at stable places to prevent it from falling.
 Do not drip or splash liquids onto the access controller; do not put on the access controller
anything filled with liquids.
 Install the access controller at well-ventilated places and do not block its ventilation
opening.
 Operate the access controller within rated input and output range.
 Do not disassemble the access controller by yourself.
 Transport, use and store the access controller under allowed humidity and temperature.
 For the access controller with a temperature monitoring unit:
Install the temperature monitoring unit in a windless indoor environment, and maintain 
the indoor ambient temperature at 15°C to 32°C .
Warm up the temperature monitoring unit for more than 20 minutes after power-on to 
enable the temperature monitoring unit to reach thermal equilibrium.
Electrical Safety
 Improper battery use might result in fire or explosion.
 When replacing battery, make sure that the same model is used.
 Use recommended power cables in the region under their rated specification.
 Use the power adapter provided with the access controller; otherwise, it might result in
injury and device damage.
 The power supply should conform to the Safety Extra Low Voltage (SELV) requirements,
and supply power with rated voltage that conforms to Limited Power Source in IEC60950-1.
Please note that the power supply requirement is subject to the device label.
 Connect the device (I-type structure) to the power socket with earthing.
 The appliance coupler is a disconnection device. When using the coupler, keep the angle
for easy operation.
