Installation Precautions
Note
：
To avoid improper use of equipment damage and personal injury, please
observe the following precautions
Installation safety precautions
The power should be kept off during the installation, while wearing anti-static wrist, and to
ensure well touch between anti-static wrist and skin to avoid potential safety hazard;
The switch just work normally when it is powered by the correct power supply. Make sure
that the power supply voltage matches the voltage indicated by the switch
Before powering on the switch, make sure that the power circuit is not overloaded, which
may affect the normal operation of the switch and even cause unnecessary damage
To avoid the risk of electric shock, do not open the case while the switch is working. Do
not open the case even when it is not powered
Before cleaning the switch, unplug the switch from the power cord and do not wipe it with
wet cloth. Do not wash it with liquid
Temperature and humidity
To ensure the long-term stability working of the switch , please maintain a certain
temperature and humidity environment. High or low humidity easily lead to leakage of
insulation materials, deformation and even the corrosion of metal parts, the temperature
is too high will accelerate the aging process of insulating materials, seriously affecting
the service life of equipment. The normal operation of this series of switches and storage
temperature / humidity are as follows
