CJ-series PLCs CJ-series FL-net Units can be mounted to either a CJ-series CPU Rack or a
CJ-series Expansion Rack. Mount the Units to any of the positions shown in
the following diagram, and secure with the slider on the top and bottom of the
Unit. Up to four FL-net Units can be mounted to a single PLC. If an FL-net Unit
is mounted in combination with other CPU Bus Units (e.g., Controller Link
Units), the maximum total number of CPU Bus Units that can be mounted is
16.
Note The current consumption of the CJ1W-FLN22 FL-net Unit is 370 mA maxi-
mum. Make sure that the total current consumption of all Units mounted to the
CPU Rack or Expansion Rack to which the FL-net Unit is mounted does not
exceed the capacity of the Power Supply Unit.

3-6-1 Basic Installation Precautions
• Take the greatest care when installing the Ethernet System, being sure to
follow ISO 8802-3 specifications. You must obtain a copy of these specifi-
cations and be sure you understand them before attempting to install an
Ethernet System. Unless you are already experienced in installing com-
munications systems, we strongly recommend that you employ a profes-
sional to install your system.
• Do not install Ethernet equipment near sources of noise. If noise-prone
environments are unavoidable, be sure to take adequate measures
against noise interference, such as installing network components in
grounded metal cases, using optical links in the system, etc.
