Connections and Wiring

Wiring Guidelines

The Integrated Controllers use a 12 VDC-compliant power supply to provide power through the rear 2-pin 3.5 mm mini-Phoenix PWR connector, or through the 4-pin 3.5 mm mini-Phoenix (female) captive-wire connector used for data communication and power transfer. Use the power requirements referenced in the product’s Specifications table to determine the power draw.

The incoming PWR and GND cable from the power supply must be connected to the corresponding locations within the PWR connector.

Use only one power source for the device at a time. Using both the 2-pin mini- Phoenix PWR connector and the 4-pin mini-Phoenix AXLink connector at the same time may cause permanent damage to the device.

Apply power to the device only after installation is complete.

Wiring length guidelines

Refer to the following table for the wiring length information used with the NI-3101:

Wiring Guidelines - NI-3101 @ 900 mA

Wire size	Maximum wiring length
18 AWG	120.41 feet (39.70 meters)
20 AWG	76.45 feet (23.30 meters)
22 AWG	49.36 feet (15.04meters)
24 AWG	30.08 feet (9.17 meters)

Preparing captive wires

You will need a wire stripper and flat-blade screwdriver to prepare and connect the captive wires.

Never pre-tin wires for compression-type connections.

1.Strip 0.25 inch (6.35 mm) of insulation off all wires.

2.Insert each wire into the appropriate opening on the connector (according to the wiring diagrams and connector types described in this section).

3.Tighten the screws to secure the wire in the connector. Do not tighten the screws excessively. Doing so may strip the threads and damage the connector.
