EMI
All electromagnetic interference (EMI) sources, from outside or inside of the switch and application
system, adversely affect the switch in the following ways:
x
A conduction pattern of capacitance coupling.
x
Inductance coupling.
x
Electromagnetic wave radiation.
x
Common impedance (including the grounding system) coupling.
To prevent EMI, perform the following tasks:
x
If AC power is used, use a single-phase three-wire power receptacle with protection earth (PE)
to filter interference from the power grid.
x
Keep the switch far away from radio transmitting stations, radar stations, and high-frequency
devices.
x
Use electromagnetic shielding, for example, shielded interface cables, when necessary.
Laser safety
WARNING!
x
The switch is a Class 1 laser device.
x
Do not stare into any fiber port when the switch has power. The laser light emitted from the optical
fiber might hurt your eyes.
Installation tools
No installation tools are provided with the switch. Prepare the following tools yourself:
x
Phillips screwdriver.
x
ESD wrist strap.
x
Marker.
