[Wiring Precautions]
!
CAUTION
•
When removing the cable from the module, do not pull the cable.
When disconnecting a cable without a terminal block, unscrew on the part that is connected to
the module.
Pulling the cable that is still connected to the module may cause malfunction or damage to the
module or cable.
•
Always ground the shielded cable for the programmable controller.
There is a risk of electric shock or malfunction.
•
Use applicable solderless terminals and tighten them with the specified torque.
If any solderless spade terminal is used, it may be disconnected when the terminal screw comes
loose, resulting in failure.
•
When wiring, be sure to verify the rated voltage of the product as well as the terminal layout. Fire
or failure may result if incorrect voltage is input or incorrect wiring is performed.
[Startup/Maintenance Precautions]
!
CAUTION
•
Do not disassemble or modify the module.
Doing so could cause failure, malfunction, injury or fire.
•
Switch all phases of the external power supply off when mounting or removing the module.
Not doing so may cause failure or malfunction of the module.
In the system where a CPU module supporting the online module change is used and on the
MELSECNET/H remote I/O stations, modules can be replaced online (during energizing).
However, there are some restrictions on replaceable modules and the replacement procedures
are predetermined for each module.
For details, refer to the chapter of the online module change in this manual.
•
Do not install/remove the module to/from the base unit, or the terminal block to/from
the module more than 50 times after the first use of the product. (IEC 61131-2 compliant)
Failure to do so may cause malfunction.
•
Do not touch the connector while the power is on.
Doing so may cause malfunction.
•
Switch all phases of the external power supply off when cleaning or retightening the terminal
screws and module fixing screws.
Not doing so may cause failure or malfunction of the module.
If the screws are loose, it may cause the module to fallout, short circuits, or malfunction.
If the screws are tightened too much, it may cause damages to the screws and/or the module,
resulting in the module falling out, short circuits or malfunction.
•
Always make sure to touch the grounded metal to discharge the electricity charged in the body,
etc., before touching the module.
Failure to do so may cause a failure or malfunctions of the module.
