Grounding - Samsung RRH-2WB Installation Manual

3.3 Grounding

Grounding is required for protecting complex electronic or electric systems such as power
system, communication system, and control system from lightning, over-current, over-
voltage, and electric noise. Thus, the systems can operate properly and protect human life
from electrical shock. Ground equipment minimizes the electrical potential of the
electronic device to that of the ground, which is zero electrical potential, so that it can
prevent the device from occurring electrification.

The purposes of the ground construction are as follows:

To prevent human life and the system from over-current, over-voltage, and lightning

To provide a discharge path for surge voltage generated by lightning and power switch

To protect the system from static electricity

To eliminate or minimize the high-frequency potential in the system housing

To provide a conductor for the balance and stability of high-frequency current

To stabilize the potential of the circuit against the ground
Connecting Ground Cable
In cabling, the connection of cables without the connection to the ground cable
may cause the damage of the equipment or the bodily injury of the worker.
Connect the ground cable first.
