Wiring Requirements
ATTENTION
Safety First!
Be sure to disconnect the power cord before installing and/or wiring your device.
Wiring Caution!
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.
Temperature Caution!
Be careful when handling the device. When plugged in, the device’s internal components
generate heat, and consequently the casing may feel hot to the touch.
You should also pay attention to the following items:
! 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.
! Use the type of signal transmitted through a wire to determine which wires should be kept
separate. The rule of thumb is that wiring that shares similar electrical characteristics can be
bundled together.
! Keep input wiring and output wiring separate.
! Where necessary, it is advisable to label the wiring to all devices in the system.
Connecting the Power
Connect the 12-48 VDC power line with NPort W2004’s power jack. When the power is supplied
properly, 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.
Connecting to the Network
Connect one end of the Ethernet cable to NPort W2004’s 10/100M Ethernet port and the other end
of the cable to the Ethernet network. If the cable is properly connected, NPort W2004 will indicate
a valid connection to the Ethernet in the following ways:
! The Ethernet LED maintains a solid green color when connected to a 100 Mbps Ethernet
network.
! The Ethernet LED maintains a solid orange color when connected to a 10 Mbps Ethernet
network.
! The Ethernet LED will flash when Ethernet packets are being transmitted or received.
