ATTENTIONElectrostatic Discharges
Under dry condition, excessive electrostatic discharges 
may occur. Make sure to remove electrostatic 
discharges by touching a grounded metal piece before 
touching your controller system modules.
ATTENTIONCleaning
Never use chemicals such as thinner because they melt, 
deform or discolor PCB boards.
ATTENTIONPrecautions for use of power
 Run your PLC system only after the I/O devices and 
motor devices have started. (For example, first power 
on in the PROG mode,...
