Install double safety mechanisms to ensure safety against incorrect signals that
may be produced by broken signal lines or momentary power interruptions.
When adding a new device to the network, make sure that the baud rate is the
same as other stations.
When adding a new SmartSlice I/O Unit to the Communication Unit, make
sure that the CJ1W-PNT21 PROFINET IO Controller Unit is powered
down, to prevent unexpected results when starting up the new station.
Use specified communication cables.
Do not extend connection distances beyond the ranges given in the specifications.
Always turn OFF the power supply to the personal computer, Slaves, and
Communication Units before attempting any of the following:
•
•
•

•
Be sure that all the mounting screws, terminal screws, Unit mounting screws, and
cable connector screws are tightened to the torque specified in the relevant
manuals. Incorrect tightening torque may result in malfunction.
Always use the power supply voltage specified in this manual.
Double-check all the wiring and connection of terminal blocks and connectors
before mounting the Units.
Take appropriate measures to prevent foreign objects from entering the unit when
mounting or wiring it. Failure to do so, may result in unit damage, electric shock or
fire.
Use crimp terminals for wiring. Do not connect bare stranded wires directly to
terminals.
Observe the following precautions when wiring the communication cable.

Take appropriate measures to ensure that the specified power with the rated
voltage and frequency is supplied in places where the power supply is unstable. An
incorrect supply power may result in malfunction.
Install external breakers and take other safety measures against short-circuits in
external wiring. Insufficient safety measures against short-circuits may result in
burning.
Double-check all the wiring and switch settings before turning ON the power supply.
When transporting or storing the product, cover the PCB’s with electrically
conductive materials to prevent LSI’s and IC’s from being damaged by static
electricity, and also keep the product within the specified storage temperature
range.
When transporting the Unit, use special packing boxes and protect it from being
exposed to excessive vibration or impacts during transportation.
Do not attempt to disassemble, repair, or modify any Units.
Do not remove the network cable during operation. Removing the network cable
result in communication failures.
Mounting or dismounting the CJ1W-PNT21 PROFINET IO Controller Unit,
Power Supply Units, I/O Units, CPU Units, or any other Units.
Assembling a Unit.
Setting DIP-switches or rotary switches.
Connecting or wiring the cables.
Connecting or disconnecting connectors.
Separate the communication cables from the power lines or high-tension lines.
Do not bend the communication cables.
Do not pull on the communication cables.
Do not place heavy objects on top of the communication cables.
Be sure to wire communication cable inside ducts.
Use appropriate communication cables.
