2-3 Expansion I/O Unit or Expansion Unit
This section describes the connection of Expansion I/O Units or Expansion Units to a CP1E CPU Unit.
• Expansion I/O Units and Expansion Units cannot be connected to E10/14/20 or N14/20 CPU Units.
• A total of up to three Expansion I/O Units and Expansion Units can be connected to an E30/40,
N30/40/60 or NA20 CPU Unit.

Connection cables for the Expansion I/O Units and Expansion Units are used to connect the Units.
The length can be extended by using a CP1W-CN811 I/O Connecting Cable (length: 800 mm).
Leave approximately 10mm of space between the CPU Unit and the Exapansion I/O Units or Expan-
sion Units.
