[STARTUP AND MAINTENANCE PRECAUTIONS]
WARNING
● Do not touch any terminal while the PLC's power is on. Doing so may cause electric shock or
malfunctions.
● Before cleaning or retightening terminals, cut off all phases of the power supply externally. Failure to
do so in the power ON status may cause electric shock.
● Before modifying the program in operation, forcible output, running or stopping the PLC, read through
this manual carefully, and ensure complete safety. An operation error may damage the machinery or
cause accidents.
● Do not change the program in the PLC from two or more peripheral equipment devices at the same
time. (i. e. from an engineering tool and a GOT) Doing so may cause destruction or malfunction of the
PLC program.
[STARTUP AND MAINTENANCE PRECAUTIONS]
CAUTION
● Do not disassemble or modify the PLC. Doing so may cause fire, equipment failures, or malfunctions.
For repair, contact your local Mitsubishi Electric representative.
● Turn off the power to the PLC before connecting or disconnecting any extension cable. Failure to do
so may cause device failures or malfunctions.
● Turn off the power to the PLC before attaching or detaching the following devices. Failure to do so
may cause device failures or malfunctions.
- Peripheral devices, expansion board, expansion adapter, and connector conversion adapter
- Extension modules, bus conversion module, and connector conversion module
- Battery
● Before handling the module, touch a conducting object such as a grounded metal to discharge the
static electricity from the human body. Failure to do so may cause the module to fail or malfunction.
[OPERATION PRECAUTIONS]
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.
[DISPOSAL PRECAUTIONS]
