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

Dust-proof
Dust on the switch surface will cause electrostatic adsorption, poor contact of
the metal contacts. Although the device itself has done some measures in
anti-static, but when the static electricity exceeds a certain intensity, it will still
cause fatal damage to the electronic components on the internal circuit board.
In order to prevent static electricity from affecting the normal operation of the
equipment, please note the following:
Regular dust, keep the indoor air clean;
Make sure the equipment is well grounded to ensure smooth transfer of static
electricity
Electromagnetic interference
Electromagnetic interference have an impact on the device capacitance,
inductance and other electronic components by capacitive, inductive coupling,
impedance coupling and other conductive, in order to reduce the adverse
effects caused by electromagnetic interference, please note the following
：
Power supply system to take the necessary anti-grid interference measures;
Switches should be far away from high-frequency high-power, high-current
devices, such as wireless transmitters;
If necessary, take electromagnetic shielding measures
Lightning protection
When a lightning strike occurs, a strong current will be generated in an instant
cause fatal damage to electronic equipment. To achieve better lightning
protection, please note the following
：
Make sure the rack and the ground to maintain good contact;
Make sure the power outlet is in good contact with the earth;
Reasonable wiring, to avoid the internal sense ray;
Outdoor wiring, it is recommended to use the signal lightning protection device
