Attach End Plates (PFP–M) to both ends (as shown below) when connecting
CPUs, Expansion I/O Units, or Analog Timer Units to a DIN Rail. It is also
recommended that a Spacer (PFP–S) be installed between a CPU and Ex-
pansion I/O Unit when they are mounted horizontally.

Mounting screws are included with CPUs, Expansion I/O Units, and Analog
Timer Units. They must be purchased separately for I/O Link Units.
Applicable connecting cable will vary according to which Units are connected
and whether they are mounted horizontally or vertically. All Expansion I/O
Units except the C16P and C4K use C20P–CN501 cable (5 cm) for horizon-
tal mounting and C20P–CN411 cable (40 cm) for vertical mounting. The
C16P and C4K cannot be mounted vertically. The C16P can use either of the
above–mentioned cables for horizontal mounting. The C4K can use only
C4K–CN501 cable (5 cm). For connecting I/O Link Units, use C20P–CN711
cable (70 cm).
CAUTION:
Always be sure to use only the cable that is included with the Unit. Using the
wrong cable (such as the C20 I/O Connecting Cable or I/O Link Connecting
Cable) for connecting Expansion I/O Units can cause serious damage to the
Units.
