24 Vdc External Sensor Power Source
The 24 Vdc Sensor Power source on the PXC Compact should only be used to supply
power to sensors. No accessories of any kind can be powered by this connector.
For powering actuators, use either the 24V ACTUATORS connector on the Service
Box or an external power supply.

Shield Termination

Terminating shield on the enclosure is the preferred method. The "-" termination next
to the 24 Vdc sensor power termination may be used as either a ground for the power
or as a cable shield connection. "-" is not connected to earth ground.
