The router does not provide an ESD wrist strap, prepare 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 grounding screw on the router.
EMI prevention
All electromagnetic interference (EMI) sources, from outside or inside of the router and application
system, adversely affect the router 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 router far away from radio transmitting stations, radar stations, and high-frequency
devices.
•
Use electromagnetic shielding, for example, shielded interface cables, when necessary.
Lightning protection
To enhance lightning protection for the router, follow these guidelines:
•
Make sure the router is reliably grounded.
•
Make sure the AC power outlet is reliably grounded.
•
Install a lightning protector at the power input end.
