• Always turn ON power to the PLC before turning ON power to the control system. If the PLC
power supply is turned ON after the control power supply, temporary errors may result in control
system signals because the output terminals on DC Output Units and other Units will momentarily
turn ON when power is turned ON to the PLC.
• Install external breakers and take other safety measures against short-circuiting in external wiring.
Insufficient safety measures against short-circuiting may result in burning.
