Attach the alligator clip to the rack.Figure 2 Attaching an ESD wrist strap(1) ESD wrist strap (2) Lock(3) Alligator clipEMIAll electromagnetic interference (EMI) sources, from outside or inside of the device and applicationsystem, adversely affect the device in the following ways:• A conduction pattern of capacitance coupling.• Inductance coupling.• Electromagnetic wave radiation.• Common impedance (including the grounding system) coupling.To prevent EMI, use the following guidelines:• If AC power is used, use a single-phase three-wire power receptacle with protection earth (PE)to filter interference from the power grid.• Keep the device far away from radio transmitting stations, radar stations, and high-frequencydevices.• Use electromagnetic shielding, for example, shielded interface cables, when necessary.• To prevent signal ports from getting damaged by overvoltage or overcurrent caused by lightningstrikes, route interface cables only indoors. If part of the network cable of an Ethernet port mustbe routed outdoors, install a network signal lightning arrester for the port.Lightning protectionTo better protect the device from lightning, follow these guidelines:• Make sure the grounding cable of the chassis is reliably grounded.• Make sure the grounding terminal of the AC power receptacle is reliably grounded.
