Example of combination of installation on DIN rail and direct installation
• The CPU module side can be installed on the DIN rail, and the extension modules extended by the extended extension
cable can be directly installed.
• The PLC can be installed on a 35 mm wide DIN46277 rail.
• The PLC can be easily moved and removed.
• The PLC installation height is the same as the DIN rail.
• The PLC can be installed directly in the enclosure with M4 screws.
For details on the procedures for installing on and detaching from DIN rail, refer to Page 77 Procedures for Installing on
and Detaching from DIN Rail. For mounting hole pitch, refer to Page 80 Hole pitches for direct mounting.
■Example of installation
*1 FX5-CNV-BC can only be installed directly.
5.3 Procedures for Installing on and Detaching from
DIN Rail
The CPU module can be installed on a DIN46277 rail (35 mm wide).
Preparation for installation
Connecting extension devices
Some extension devices must be mounted on the CPU module before the module is installed in the enclosure.
• Connect expansion adapters to the CPU module before mounting the PLC in the enclosure.
• Mount extension modules in the enclosure after mounting the CPU module in the enclosure.
• Expansion boards can be mounted on the CPU module after it is installed in the enclosure.
• Batteries can be replaced without dismounting the CPU module from the enclosure. However, if an expansion board is
used, the CPU module must be removed.
Affixing the dust proof sheet
The dust proof sheet should be affixed to the ventilation slits before beginning the installation and wiring work.
For the affixing procedure, refer to the instructions on the dust proof sheet.
Always remove the dust proof sheet when the installation and wiring work is completed.
