FieldPoint cFP-2120
Mount the Compact FieldPoint Backplane
You can mount the cFP-BP- x backplane on a 35 mm DIN rail, on a panel, or in a
standard 19 in. rack. Before using any of these mounting methods, record the
serial number from the back of the backplane.
Each set of mounting instructions in this document includes an instruction to
connect the protective earth (PE) ground terminal on the cFP-BP- x backplane to
the system safety ground. The backplane PE ground terminal has the following
symbol stamped beside it: . Connect the backplane PE ground terminal to the
system safety ground using 14 AWG (1.6 mm) wire with a ring lug. Use the
5/16 in. panhead screw shipped with the backplane to secure the ring lug to
the backplane PE ground terminal.

Caution If you are using UL Recognized I\O modules with the
Compact FieldPoint system, you must install the entire system in a
suitably rated, UL Listed NEMA or IP enclosure.
Caution NI recommends that you use one of the mounting systems
described in this document. If you decide to use a custom mounting
solution, make sure that the screws you use are short enough to fit in
the holes in the backplane. The screw holes are 5 mm (0.2 in.) deep.
