Altitude
Products with this logo are only for safe use in areas below 2000m altitude
◼
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:
1.
Regular dust, keep the indoor air clean;
2.
Make sure the equipment is well grounded to ensure smooth transfer of static electricity
◼
Electromagnetic interference
Electromagnetic interference has 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
：
1.
Power supply system to take the necessary anti-grid interference measures;
2.
Switches should be far away from high-frequency high-power, high-current devices, such
as wireless transmitters;
3.
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
：
1.
Make sure the rack and the ground to maintain good contact;
2.
Make sure the power outlet is in good contact with the earth;
3.
Reasonable wiring, to avoid the internal sense ray;
4.
Outdoor wiring, it is recommended to use the signal lightning protection device
