Lightning Protection Grounding
The lightning protection system is an independent system consisting of a lightning
rod, conductor and connection joint with the grounding system. The grounding
system usually is shared with the power reference grounding, and green and
yellow ground cable grounding. Lightning protection grounding is a building
requirement,notaspecicrequirementoftheChassisSwitch.
Electromagnetic Compliance Grounding
This refers to the grounding in compliance with CS-6306R electromagnetic
compatibility requirements, including shielded grounding, lter grounds, noise, and
interference control and level reference. The overall grounding requirements are
the sum total of the above. Ground resistance value should be less than 1 ohm.
The CS-6306R provides chassis grounding post in the lower front chassis, marked
as “GND”. Chassis protection grounding should be properly connected to the rack
grounding connector.
The ground cabling procedures are listed below:
Step 1 Remove the nuts from the front chassis grounding posts.
Step 2 Wrap one end of the green and yellow grounding cable to the grounding
posts.
Step 3 Attachthegroundingpostnutandtightenwell.
Step 4 Attach the other end of the grounding cable to the rack grounding
connector.
The grounding cable should be made of a good conductor, and the
diameter should be determined by the possible maximum current
that may pass through. Bare conductor cabling is forbidden.
Ground resistance value: The combined grounding resistance
should be less than 1 ohm.
