Connecting The Power; Grounding The Nport Device Server - Moxa Technologies NPort 5000 Series User Manual

• You can use the type of signal transmitted through a wire to determine which wires should be kept
separate. The rule of thumb is that wires that shares similar electrical characteristics can be bundled
together.
Keep input wiring and output wiring separate.
•
• Where necessary, it is strongly advised that you label wires to all devices in the system.

Connecting the Power

Connect the power line with the NPort's power input. If the power is properly supplied, the "Ready" LED will
show a solid red color until the system is ready, at which time the "Ready" LED will change to a green color.

Grounding the NPort Device Server

Note: This section only applies if your NPort's power input is on a terminal block.
Grounding and wire routing help limit the effects of noise caused by electromagnetic interference (EMI). Run
the ground connection from the ground screw to the grounding surface before connecting the devices.
WARNING
NPorts with a power terminal block are intended to be mounted to a well-grounded mounting surface such
as a metal panel.
