500 times or more may cause malfunction.
● Turn off the power to the PLC before connecting or disconnecting any extension cable. Failure to do
so may cause equipment failures or malfunctions.
● Turn off the power to the PLC before attaching or detaching the following devices. Failure to do so
may cause equipment failures or malfunctions.
- Peripheral devices, expansion board, expansion adapter, and connector conversion adapter
- Extension modules, bus conversion module, and connector conversion module

CAUTION
● Construct an interlock circuit in the program so that the whole system always operates on the safe
side before executing the control (for data change) of the PLC in operation. Read the manual
thoroughly and ensure complete safety before executing other controls (for program change,
parameter change, forcible output and operation status change) of the PLC in operation. Otherwise,
the machine may be damaged and accidents may occur by erroneous operations.
CAUTION
● Please contact a certified electronic waste disposal company for the environmentally safe recycling
and disposal of your device.
