2.5 Wiring Earth Ground
To ensure the system will not be damaged by noise or any electrical shock,
we suggest you to make exact connection with JetNet 4508 V2 series with
Earth Grounding.
On the bottom side of JetNet 4508 V2 series, there is one earth ground
screw. Loosen the earth ground screw by screw drive; then tighten the
screw after earth ground wire is well connected.
Without the exact system chassis grounding, the communication may
intereferred by the external noise, such as lighting, fast electrical filed
transient or electrostatic discharge.
