Always wear an ESD wrist strap. Make sure the wrist strap makes skin contact and is reliably
grounded when installing the transceiver module.
The ESD wrist strap is not provided with the device. Order it yourself.
To attach an ESD wrist strap:
1.
Wear the wrist strap on your wrist.
2.
Lock the wrist strap tight around your wrist to maintain good contact with the skin.
3.
Secure the wrist strap lock and the alligator clip lock together.
4.
Attach the alligator clip to the rack.
5.
Make sure the rack is reliably grounded.

EMI
All electromagnetic interference (EMI) sources, from outside or inside of the device and application
system, 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, perform the following tasks:
•
If AC power is used, use a single-phase three-wire power receptacle with protection earth (PE) to
filter interference from the power grid.
