Grounding the Industrial PoE Switch
CAUTION
Be sure to disconnect the Industrial PoE Switch from the DC power source before
installing and wiring the device.
Wiring
considerations
The following wiring considerations are recommended:
• Signal lines must not be directly connected to outdoor wiring.
• Use separate paths or conduits to route wiring for power and device data cables. To avoid
interference, wires with different signal characteristics route separately. If power wiring and
device data cables must cross make sure that the wires are perpendicular at the
intersection point.
• Use the type of signal transmitted through a wire to determine which wires should be kept
separate. The rule of thumb is wiring that shares similar electrical characteristics can be
bundled together.
• Keep input and output wiring separated.
CAUTION
The Industrial PoE Switch is intended to be grounded to a well-grounded mounting
surface such as a metal plate. Install the grounding wire prior to connecting any other
device to the Industrial PoE Switch.

grounding
Grounding the Industrial PoE Switch helps limit the effects of noise due to electromagnetic
interference (EMI) via proper grounding. Always run the ground connection from the ground
screw to a grounding surface before connecting the Industrial PoE Switch to a DC power
source. See Figure 7.
