Connections and Wiring
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.

Wiring a power connection

To use the 2-pin 3.5 mm mini-Phoenix connector with a 12 VDC-compliant power supply, the
incoming PWR and GND cables from the external source must be connected to their corresponding
locations on the connector (FIG. 2).

Wiring Guidelines - Indirect Power (via PoE)

Power-over-Ethernet (PoE) can be used to indirectly provide DC power to this 802.3af-compliant
device via the unused wire pairs in the UTP or STP Ethernet cable (RJ-45 pins 4, 5, 7, and 8).
PoE power is overridden if a direct power feed (via the rear 2-pin PWR connector) is detected.
Any 802.3af-compliant PoE switch (such as the NXA-ENET24 PoE) can automatically detect the
MAX device by its authenticated PoE signature and sense its required load before applying power
to the PoE Ethernet port on a target device.
PoE connections work with all existing Category (CAT) 3, 4, 5, 5e or 6 network
cabling (including patch cables and patch-panels, outlets, and other connecting
hardware) without requiring modification.

PoE - Special wiring instructions

Before beginning the connection from the PoE switch to the target MAX unit, follow these
instructions carefully:
When using PoE, you must FIRST ground the unit to provide ESD protection.
The length of the GND wire should not exceed 6 feet (1.83 meters).

Refer to the procedures outlined within the previous Preparing captive wires section on
page 5.
Install a single wire into the (-) GND side of the rear green 2-pin mini-Phoenix connector
(FIG. 3).
Connect this wire to a grounded source (FIG. 3). This GND wire provides the necessary
ESD protection to the unit. Only after this step has been completed, can you continue on
to the wiring of the PoE connection.
