[Startup and Maintenance Precautions]
[Disposal Precautions]
CAUTION
● Do not disassemble or modify the module. Doing so may cause failure, malfunction, injury, or a fire.
● Shut off the external power supply (all phases) used in the system before mounting or removing a
module. Failure to do so may cause the module to fail or malfunction.
● After the first use of the product (module and display unit), do not connect/disconnect the product
more than 50 times (in accordance with IEC 61131-2). Exceeding the limit may cause malfunction.
● Tighten the connector screws within the specified torque range. Undertightening can cause drop of
the component or wire, short circuit, or malfunction. Overtightening can damage the screw and/or
module, resulting in drop, short circuit, or malfunction.
● Before handling the module, touch a conducting object such as a grounded metal to discharge the
static electricity from the human body. Failure to do so may cause the module to fail or malfunction.
● When performing online operations of the running module from an external device such as a personal
computer connected, read the relevant manuals carefully and ensure that the operation is safe before
proceeding.
● Before changing any setting of the module, read the relevant manuals carefully, ensure the safety,
and change the operating status of the CPU module to STOP.
Especially when operating the module in the network system, ensure the safety thoroughly because
controlled machines are likely to be moved inadvertently. Improper operation may damage machines
or cause accidents.
