result in electric shock, fire, erroneous operation, and damage to or deterioration of the product.
Completely turn off the power supply before loading or unloading the module.
Not doing so could result in electric shock or damage to the product.
Make sure all modules are loaded correctly and securely.
Not doing so could cause a malfunction, failure or drop.
Make sure I/O and extension connector are installed correctly.
Poor connection could cause an input or output failure.
When install the PLC option card in environment of much vibration, be sure to insulate the
