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.
●
Use the battery for memory backup in conformance to this manual.
-
Use the battery for the specified purpose only.
-
Connect the battery correctly.
-
Do not charge, disassemble, heat, put in fire, short-circuit, connect reversely, weld, swallow or
burn the battery, or apply excessive forces (vibration, impact, drop, etc.) to the battery.
-
Do not store or use the battery at high temperatures or expose to direct sunlight.
-
Do not expose to water, bring near fire or touch liquid leakage or other contents directly.
-
When replacing the battery, make sure to use our specified product (FX3U-32BL).
-
When a battery error occurs ("BAT" LED is lit in red), follow the description in this manual.
Incorrect handling of the battery may cause heat excessive generation, bursting, ignition, liquid
leakage or deformation, and lead to injury, fire or failures and malfunction of facilities and other
equipment.
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.
●
After the first use of the SD memory card, do not insert/remove the memory card more than 500 times.
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 adapter and connector conversion adapter
-
Extension modules, bus conversion module, and connector conversion module
-
