Legrand PDU User Guide 45
The following procedure illustrates a DPX2 sensor cable with three head connectors. Your sensor cable may
have fewer head connectors.
Warning: If there are free head connectors between a DPX2 sensor cable's RJ-12 connector and the final
attached DPX2 sensor package, the sensor packages following the free head connector(s) on the same
cable do NOT work properly. Therefore, always occupy all head connectors prior to the final sensor
package with a DPX2 sensor package.
To connect DPX2 to the Legrand PDU:
1. Connect a DPX2 sensor package to the first head connector of the DPX2 sensor cable.
2. Connect remaining DPX2 sensor packages to the second and then the third head connector.
Tip: If the number of sensors you are connecting is less than the number of head connectors on your
sensor cable, connect them to the first one or first two head connectors to ensure that there are NO free
head connectors prior to the final DPX2 sensor package attached.
3. Use an RJ-12 to RJ-45 adapter to connect the DPX2 sensor package(s) to the Legrand PDU.
a. Connect the adapter's RJ-12 connector to the DPX2 sensor cable.
b. Connect the adapter's RJ-45 connector to the RJ-45 SENSOR port of the Legrand PDU.
OR you can directly connect the DPX2 sensor package to a DX sensor chain without using any RJ-12 to
RJ-45 adapter. See
Connecting a DPX2 Sensor Package to DX2, DX or DPX3
(on page 46).
