1. Mount the Compact FieldPoint Backplane
You can mount the cFP-BP-x backplane on a 35mm 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 Keep in mind these requirements for space and cabling
clearance:
• Allow at least 51 mm (2 in.) all around the backplane for air
circulation.
• Allow 38 mm (1.5 in.) below and 51 mm (2 in.) above the controller.

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.

2. Bolt or screw the panel-mount accessory to a panel.
3. Connect the PE ground terminal on the cFP-BP-x to safety ground.
Caution Disconnect power before removing the backplane from the
panel.
Mounting the Backplane on a DIN Rail
NI recommends DIN rail mounting for the cFP-BP-4 only. Use panel mounting or
rack mounting for the cFP-BP-8. The DIN rail mounting kit is NI part number
778614-01.
1. Fasten the DIN rail clip to the cFP-BP-4 using a number 2 Phillips screwdriver
and the 8-32 × 5/16 in. countersink screws shipped with the clip.
