Connecting the Hardware 
This section describes how to connect the NPort 5400 to serial devices for first time testing 
purposes. We cover Wiring RequirementsConnecting the PowerGrounding the NPort 5400

Wiring Requirements 
 
ATTENTION 
Safety First! 
Be sure to disconnect the power cord before installing and/or wiring your NPort 5400. 
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! 
Please take care when handling the NPort 5400. When plugged in, the NPort 5420/5430/5430I’s 
internal components generate heat, and consequently the casing may feel hot to the touch.
 
 
You should also heed the following: 
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
  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 wiring that shares similar electrical characteristics can 
be bundled together. 
y
  Keep input wiring and output wiring separate. 
y
  Where necessary, it is strongly advised that you label wiring to all devices in the system. 
Connecting the Power 
Connect the 12-48 VDC power line with the NPort 5400’s terminal block. 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 5400 
Grounding and wire routing helps limit the effects of noise caused by electromagnetic interference 
(EMI). Run the ground connection from the ground screw to the grounding surface prior to 
connecting devices.
