Cleanliness

Dust accumulated on the device can be attracted by static electricity and cause poor contact at metal contact points. Some measures have been taken to prevent static electricity, but excessive static electricity can cause severe damage to the electronic components on the internal circuit board. To avoid the effects of static electricity on device operation, please pay close attention to the following:

• Dust the device regularly and keep the indoor air clean.
• Ensure the device is properly grounded and that static electricity is discharged.

Electromagnetic Interference

Electronic components such as capacitors and inductors on the device can be affected by external interference, including conducted emissions through capacitive coupling, inductive coupling, and impedance coupling. To reduce interference, please ensure the following measures are taken:

- Use a power supply that effectively filters interference from the power grid.

• Keep the device away from high-frequency, high-current equipment, such as radio transmitting stations.
• Use electromagnetic shielding when necessary.

Lightning Protection

Extremely high voltage currents can be generated instantly when lightning occurs, and the air in the discharge path can be instantly heated to 20,000°C. Since this instantaneous current is strong enough to damage electronic devices, more effective lightning protection measures should be taken.

• Ensure the rack and device are properly grounded.
• Make sure the power socket has good contact with the ground.
• Maintain a proper cabling system to avoid induced lightning.
• Use a signal SPD (Surge Protective Device) when wiring outdoors.

Note: For detailed lightning protection measures, refer to section 3.1, Connect to Ground.
