The power input is filtered internally on the RXi2-UP IPC. Directly after the power connector
Frame GND and Power
–
are hard connected. When using a power supply with a supply
reference to PE ground, connect the +24 V to power plus and the GND to power minus.
ATTENTION
Never use a power supply generating a -24 V output if the positive supply is related to PE
ground. It will be shortened if any external device is connected to the RXi2-UP IPC.
ATTENTION
The power input is secured with one 10 A fuse. If the input power exceeds the limits, the
fuse will be blown to protect all circuitry within the RXi2-UP IPC. Contact Emerson for a
suitable replacement.

CFast Connector
Located on the front of the RXi2-UP IPC is a CFast Type 1 flash connector. CFast is a variant
of a CompactFlash that supports a higher maximum transfer rate than current Compact
Flashcards. Standard CFast cards can be used for the storage of data or the operating
system. The device is connected to a standard SATA port of the COM Express module and is
hotplug capable with standard OS.
