NXA-PDU-1508-8 Power Distribution Unit
MASTER Connector
The 3.5mm 4-pin captive-wire AxLink connector labelled “MASTER” provides AxLink connectivity between
the PDU and the NetLinx Master (see FIG. 7).
TEMP Connector
The 3.5mm 2-pin captive-wire connector labelled “TEMP” (see FIG. 7) provides the option to connect a
Remote Temperature Sensor (RTS). The NXA-PDU-1508-8 comes with one ENV-VST-TSO Temperature
Sensor (FG2050-22).
Connect either wire from the RTS to either pin on the TEMP connector (FIG. 8).
Preparing Captive Wires
1.
Strip 0.25 inch (6.35 mm) of wire 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. Turn the flat-head screws clockwise to secure the wires in the connector.
AxLink Data and Power Connections
Connect the AxLink device’s AxLink connector to one of the AxLink connectors (1-8) on the rear panel of the
PDU for data and 12 VDC power as shown in FIG. 9.
This connector is always ON.

The NXA-PDU-1508-8 is also compatible with the ENV-VST-TSF Indoor Flush Mount
Temperature Sensor (FG2050-21 - not included).
Do not over-torque the screws; doing so can bend the seating pins and damage the
connector.

If the PDU is connected to a NetLinx Master that is self-powered (powered by a
stand-alone power supply other than the PDU, or the DVX-2100HD which features an
internal power supply), do not use the AxLink Power connection between the PDU
and the NetLinx Master.
