inductance coupling, electromagnetic wave radiation, and common
impedance (including the grounding system) coupling. To resist the
interference, make sure to:
The alternating power supply system is TN system. Adopt single-phase
three wire socket with protection ground wire to filter electricity power
interference by the device filter circuit.
Keep the device far from the strong power radio launchers, radar
launchers, and high frequency and high-current equipment.
Use electromagnetic shielding when necessary, such as you can use
shielded cable
Require you using interface cable indoors, not use it outdoors, to
prevent overvoltage and over electricity damaging the device by
thunder.
2.2.5
Lightning protection
Although the switch is designed to be lightning resistant, your device
can get damaged when excessive lightning is present. To protect your
device against lightning,
Use protective ground wire to connect to the earth ground.
Ensure the ground point of the power socket is well connected to the
earth ground.
Add a lightning arrester onto the front end of the power input to better
protect the power supply from lightning strikes.
2.2.6
Grounding requirements
Using a good grounding system to protect your switch against lightning
shocks, interferences, and ESD is essential to the operating reliability of your
switch.
2.2.7
Wiring cable requirements
Cables connect the device should be indoors, not wiring outdoors. When you
wiring indoors, you should pay attention to the followings:
Do not wiring cables in working area, so that it can avoid the cables to be
damaged or dropped from ceiling.
When you wiring cables, the cables should be straight, not curved, or
not twined.
