[Wiring Precautions]
• Plug the bus connection cable by inserting it into the connector of the connected module until it
"clicks".
After plugging, check that it has been inserted snugly.
Not doing so can cause a malfunction due to a contact fault.
• Plug the communication cable into the connector of the connected module and tighten the
mounting and terminal screws in the specified torque range.
Undertightening can cause a short circuit or malfunction.
Overtightening can cause a short circuit or malfunction due to the damage of the screws or
module.
[Test Operation Precautions]
• Before performing test operation (bit device on/off, word device's present value changing,
timer/counter's set value and present value changing, buffer memory's present value changing)
for a user-created monitor screen, system monitoring, special module monitoring or ladder
monitoring, read the manual carefully to fully understand how to operate the equipment.
During test operation, never change the data of the devices which are used to perform
significant operation for the system.
False output or malfunction can cause an accident.
[Startup/Maintenance Precautions]
• When power is on, do not touch the terminals.
Doing so can cause an electric shock or malfunction.
• Before starting cleaning or terminal screw retightening, always switch off the power externally in
all phases.
Not switching the power off in all phases can cause a module failure or malfunction.
Undertightening can cause a short circuit or malfunction.
Overtightening can cause a short circuit or malfunction due to the damage of the screws or
module.
• Do not disassemble or modify the module.
Doing so can cause a failure, malfunction, injury or fire.
• Do not touch the conductive and electronic parts of the module directly.
Doing so can cause a module malfunction or failure.
