2.5.3 Grounding the Device
Electromagnetic Interference (EMI) affects the transmission performance of a device.
By properly grounding the device to earth ground through a drain wire, you can setup
the best possible noise immunity and emissions.
Figure 2.8 Grounding Connection
Note! Routing communications and power wiring through the same conduit
may cause signal interference. To avoid interference and signal degra-
dation, route power and communications wires through separate con-
duits.
Caution! Do not disconnect modules or cabling unless the power is first switched
off.
The device only supports the voltage outlined in the type plate. Do not
use any other power components except those specifically designated
for the switch device.
Caution! Before connecting the device properly ground the device. Lack of a
proper grounding setup may result in a safety risk and could be hazard-
ous.
Caution! Do not service equipment or cables during periods of lightning activity.
Caution! Do not block air ventilation holes.
