2.2.4 Electromagnetic Requirement
This jamming sources, no matter from device or exterior application system, exert
influences on devices through capacitance coupling, inductance coupling,
electromagnetic wave radiation, common impedance (including grounding system)
and conducting wire (power wire, cable and output wire). Pay attention to the
following points:
Adopt effective anti power grid interference measures to the power supply
system.
It is better for the switch not to work with the grounding device or anti-lightning
device of the electrical device.
Keep away from the strong power radio transmission station, radar
transmission station, and high-frequency current device.
Adopt necessary electromagnetic shield mode.
2.2.5 Anti-lightning
SM2300-28TC-AC makes a lot of consideration in anti-lightning and necessary
measures are adopted. But when the lightning strength exceeds a certain tolerance,
it will still damage the switch to reach better anti-lightning effect.
The user is recommended to do the following:
Ensure the PGND of the chassis is well grounded using the protective ground
wire.
Ensure that the ground touch point of the AC power socket is well grounded.
The power arrester can be added in the front of the power input end, which can
greatly enhance the anti-lightning capability of the power.
To reach better anti-lightning effect, for the outdoor signal line connected by
the SM2300-28TC-AC interface switch module, the user can add the special
lightning arrester device in the front of the signal line input en
d.
