2、Make sure that the equipment is well grounded to ensure
the smooth transfer of static electricity.
interference
Electromagnetic interference will affect the electronic components
such as capacitors and inductors inside the device by means of
capacitive coupling, inductive coupling, impedance coupling, etc.
To reduce the adverse effects caused by electromagnetic
interference, please pay attention to the following:
1、The power supply system takes necessary measures
against grid interference;
2、The switch should be away from high-frequency, high-
power, high-current equipment, such as wireless transmitters;
3、Take electromagnetic shielding measures when necessary.
lightning protection needs
When a lightning strike occurs, a strong current is generated in an
instant, and the air in the discharge path is instantaneously heated
to 20,000 degrees Celsius, and an instantaneous large current is
enough to cause fatal damage to the electronic device. For better
lightning protection, please note the following:
