31Grounding Terminal Connection - MandatoryAny person that gets in contact with 2N® Helios may carry an electrostatic charge ofseveral thousands of Volts. Drawing one‟s finger near to the 2N® Helios metal panelmay result in spark discharge. The purpose of the grounding terminal is to protect theproduct against this discharge. The terminal carries the charge from the panel to theground directly, not through the 2N® Helios circuits.Where no grounding cable is available, it is possible to connect the grounding terminalwith any of the telephone line terminals*). In some telephone systems one lineterminal is directly connected with the ground, the others carry current to the groundthrough overvoltage protection.Note This connection eliminates direct connection of the line conductor onto thepanel because there is a protective element between the panel and thegrounding terminal.
