Refer to the user's manual of the network system to use for a description of the network system safety precautions.
[DESIGN PRECAUTIONS] ! CAUTION Make sure to initialize the network system after changing parameters of the MELSEC-ST system or the network system. If unchanged data remain in the network system, this may cause malfunctions. Do not install the control wires or communication cables together with the main circuit or power wires. Keep a distance of 100 mm (3.94 inch) or more between them. Not doing so could result in malfunctions due to noise.
[INSTALLATION PRECAUTIONS] ! CAUTION Make sure to securely connect each cable connector. Failure to do so may cause malfunctions due to poor contact. DIN rail must be conductive; make sure to ground it prior to use. Failure to do so may cause electric shocks or malfunctions. Undertightening can cause a drop, short circuit or malfunction. Overtightening can cause a drop, short circuit or malfunction due to damage to the screw or module.
[STARTUP AND MAINTENANCE PRECAUTIONS] ! DANGER Do not touch the terminals while power is on. Doing so could cause shock or erroneous operation. Make sure to shut off all phases of the external power supply for the system before cleaning the module or tightening screws. Not doing so can cause the module to fail or malfunction. [STARTUP AND MAINTENANCE PRECAUTIONS] ! CAUTION Do not disassemble or modify the modules. Doing so could cause failure, erroneous operation, injury, or fire.
