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 ra
tings
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 feel hot to the touch. Take care when handling
unit. Be sure to leave adequate 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
