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.

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.

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.

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 NPort IA5150/5250’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 NPort IA5150/5250 Series
Grounding and wire routing helps 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.
