4Motion Installation Manual, Ver.3.5 - Alvarion

Chapter 2 - Safety and PrecautionsESD Precautions2.2 ESD PrecautionsThe BTS includes devices that may be damaged by accidental introduction of ground or foreign voltages.Electrostatic discharge on a component at a voltage exceeding 600 Volts may damage the component,even if mounted on a board.All electronic components used in 4Motion are subject to ESD electrostatic discharges. Electrostaticdischarges at voltage ratings below 4000V are not normally detected or perceived in any other form bythe persons causing the actual discharges.For example, the natural movements of a person wearing synthetic clothing may generate electrostaticvoltages exceeding 10,000V.Components are damaged by an electrical break in the ultra-thin insulating layer in the integratedcircuits (measuring typically 0.0001 mm). The damage may be serious and cause an immediate functionfailure, or remain latent and occur at a later time (even after several years).4Motion Installation Manual15
