Safety Information
Safety Requirements
Before you begin installing the device, read through the following safety
guidelines to prevent personal injury or property damage.
Seek assistance from a trained professional installer, especially if it is your
first time to install this device.
Choose your installation site carefully, noting the location of electric power
and circuit lines and ensuring that there are no obstructions.
Do not attempt to service or open the device by yourself. Bring it to a qual-
ified personnel or service center for repairs.
Electrostatic Discharge Requirements
Follow the steps below to protect components from electrostatic discharge:
1.
Wear an ESD wrist strap when installing the device.
2.
Handle the power adapter by its edge and do not touch any component or
printed circuit boards.
Temperature/Humidity Requirements
Make sure to keep the temperature and humidity of the installation location at
an optimal level. Very high temperatures may cause poor insulation, power
leakage, mechanical property changes, and metal component corrosion. Very
high temperatures will also accelerate insulation aging, which will greatly
degrade reliability and even severely shorten operation life.
Under over-low humidity environments, insulation spacers may shrink, result-
ing in loosening of mounting screws. Extremely low humidity may also cause
static electricity, which will damage the circuit.
Anti-Interference Requirements
Possible interference sources, whether from external equipment or device
application system, will affect the device by the conducting modes of captive
coupling, inductance coupling, electric magnetic wave radiation, public resis-
tance (including grounding system) coupling, cable (including power cable,
signal cable, transmission cable), and more and so on).
Take measures to efficiently prevent the power supply system from power
grid interference.
Do not install the device close to any electrical grounding device or light-
ning protection system. Place the device’s own grounding and lightning
