Connections and Wiring
12
NI-3101-SIG Signature Series NetLinx Integrated Controller
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.
Wiring length guidelines
Refer to the following table for the wiring length information used with the NI-3101:
Preparing captive wires
You will need a wire stripper and flat-blade screwdriver to prepare and connect the captive wires.
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.
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.
