AMX NetLinx Integrated Controllers NI-700/900 - Manual (Page 20)

Connections and Wiring
16 NI-700 & NI-900 Hardware Reference Guide
The AXlink port can be used to supply power to downstream AXlink-compatible devices as long as both
the power required is LESS THAN 2 Amps total and the external power supply feeding the NI unit has
the necessary power capability.
Wiring Guidelines
The Integrated Controllers use a 12 VDC-compliant power supply to provide power to the Controller
through the rear 2-pin 3.5 mm mini-Phoenix PWR connector. Use the power requirements information
described 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 tables for the wiring length information used with your particular NetLinx
Integrated Controller:
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.

This unit should only have one source of incoming power.
Using more than one source of power to the Controller can result in damage to the
internal components and a possible burn out.
Apply power to the unit only after installation is complete.
