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

Installation desk requirement
Regardless of whether the switch is installed in a rack or on another horizontal workbench,
be aware of the following:
Make sure the rack or workbench is stable, strong, and can withstand at least 5.5Kg
