NPort IA and IAW5000A-I/O
Connecting the Hardware
ATTENTION
Before connecting the hardware, follow these important wiring safety precautions:
Disconnect power source
Do not install or wire this unit or any attached devices with the power connected. Disconnect the power
before installation by removing the power cord before installing and/or wiring your unit.
Follow maximum current ratings
Calculate the maximum possible current in each power wire and common wire. Observe all electrical codes
dictating the maximum current allowable for each wire size.
If the current goes above the maximum ratings, the wiring could overheat, causing serious damage to your
equipment.
Use caution - unit may get hot
The unit will generate heat during operation, and the casing may be too hot to the touch. Take care when
handling the unit. Be sure to leave enough space for ventilation.
The following guidelines will help ensure trouble-free signal communication with the NPort.
•
Use separate paths to route wiring for power and devices to avoid interference. Do not run signal or
communication wiring and power wiring in the same wire conduit. The rule of thumb is that wiring that
shares similar electrical characteristics can be bundled together.
•
If power wiring and device wiring paths must cross, make sure the wires are perpendicular at the
intersection point.
•
Keep input wiring and output wiring separate.
•
Label all wiring to each device in the system for easier testing and troubleshooting
Connecting to the Network
Use the supplied Ethernet cable to connect the NPort to your Ethernet network. If the cable is properly
connected, the NPort will indicate a valid connection to the Ethernet as follows:
•
A green Ethernet LED indicates a valid connection to a 100 Mbps Ethernet network.
•
An orange Ethernet LED indicates a valid connection to a 10 Mbps Ethernet network.
•
A flashing Ethernet LED indicates that Ethernet packets are being transmitted or received.
Connecting the Power
The unit can be powered by connecting a power source to the terminal block.
1. We recommend using 24 to 16 AWG wire. Strip 9 to 10 mm of insulation off the end of the wire before
inserting it into the terminal block hole.
2. The power input range is from 12 to 48 VDC.
To remove the wire from the terminal block, use a flathead screwdriver to push the orange slot next to the
terminal block hole, and then pull the wire out.
Note that the unit does not have an on/off switch. It automatically turns on when it receives power. The
PWR LED on the front panel will glow to indicate that the unit is receiving power. There are two DC power
inputs for redundancy.
