Handling precautions
When installing the PROFINET IO Controller Unit on the PLC system, observe
the following handling precautions.
• Always turn OFF the power supply to the PLC before mounting or
dismounting a Unit or connecting or disconnecting cables.
• Provide separate conduits or ducts for the I/O lines and network cables to
prevent noise from high-tension lines or power lines.
• When wiring leave the label on top of the Unit attached. Removing the label
prior to wiring may result in malfunction if foreign matter enters the Unit.
• Remove the label after completing the wiring to ensure proper air
circulation. Leaving the label attached may result in malfunction.

Mounting the CJ1W-PNT21
The PROFINET IO Controller Unit can be mounted to any slot in either a CJ-
series CPU Rack, or Expansion Rack. The CJ-series PLC supports up to 3
Expansion Racks, in addition to the CPU Rack.
The figure below shows the number and the positions of the slots to which
PROFINET IO Controller Units can be mounted. The CJ1W-PNT21 can be
mounted using the sliders on the top and bottom of the Unit. In a single CJ1
PLC system, up to 16 PROFINET IO Controller Units can be mounted. If the
CJ1W-PNT21 is mounted in combination with other CPU Bus Units (e.g.,
Ethernet Units), the maximum number of CPU Bus Units that can be mounted
is 16.

Note
The maximum current consumption of the CJ1W-PNT21 PROFINET IO Controller Unit
is 420 mA. Make sure that the total current consumption of all the Units connected to
the same CPU Backplane or Expansion Backplane does not exceed the output capacity
of the Power Supply Unit.
