NPort 6000 Series User’s Manual Getting Started

You should also heed the following guidelines:

y Use separate paths to route wiring for power and devices. If power wiring and device wiring

paths must cross, make sure the wires are perpendicular at the intersection point.

NOTE: Do not run signal or communication wiring and power wiring in the same wire conduit.

To avoid interference, wires with different signal characteristics should be routed separately.

y The type of signal transmitted through a wire should determine which wires should be kept

separate. The rule of thumb is that wires sharing similar electrical characteristics may be

bundled together.

y Keep input wiring and output wiring separate.

y It is good practice to label the wiring to all devices in the system.

Connecting the NPort 6600-32/16/8-48V’s Power

To connect the NPort 6600-32/16/8-48V’s power cord with its terminal block, follow the steps

given below:

V+ V-

1. Loosen the screws on the V+ and V- terminals of the NPort

6600-32/16/8-48V’s terminal block.

2. Connect the power cord’s 48 VDC wire to the terminal block’s V+

terminal, and the power cord’s DC Power Ground wire to the terminal

block’s V- terminal, and then tighten the terminal block screws. (Note:

The NPort 6600-32/16/8-48V can still operate even if the DC 48V and DC

Power Ground are reversed.)

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.

NOTE

You should use 8 kg-cm of screw torque and 22-14 AWG of suitable electric wire to connect the

NPort 6600-32/16/8-48V’s power cord to its terminal block.

Grounding the NPort 6600-32/16/8-48V

Grounding and wire routing help limit the effects of noise due to electromagnetic interference

(EMI). Run the ground connection from the ground screw to the grounding surface prior to

connecting devices.

V+ V-

The Shielded Ground (sometimes called Protected Ground) contact is the

second contact from the right of the 5-pin power terminal block connector

located on the rear panel of the NPort 6600-32/16/8-48V. Connect the SG wire

to the Earth ground.

ATTENTION

This product is intended to be mounted to a well-grounded mounting surface such as a metal

panel.
