Equipment Rack Ground Bonding

The Importance of Electronic Equipment Grounding

Electronic equipment can be sensitive to stray currents, electromagnetic interference, electrostatic discharge and other electrical disturbances “noise”.  To prevent electrical disturbances from affecting computers and other electrical equipment two entirely different and separate grounding systems are required.  The power distribution system must be grounded and the computer equipment and enclosures should be connected to a grounding grid or common bonding network. 

The goals of the grounding system within a data center are to equalize electrical potentials and to create a low impedance path to ground.  You want a grounding system that directs damaging currants away from the equipment.  TIA-607-C requires each rack to bond directly to the grounding grid or common bonding network, directing current away from sensitive electronics.
