1. Mount the Compact FieldPoint Backplane
You can mount the cFP-BP-xbackplane 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-xbackplane 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.
