[Startup and Maintenance Precautions]
WARNING
● Do not touch any terminal while the programmable controller'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, performing forced output, or running or stopping the programmable
controller while the system is running, 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 programmable controller from two or more peripherals at the same
time. (such as from an engineering tool and a GOT) Doing so may cause destruction or malfunction of
the programmable controller program.
● Use the battery for memory backup in conformance to the user's manual (Hardware) of the CPU
module used.
- Use the battery for the specified purpose only.
- Connect the battery correctly.
- Do not charge, disassemble, heat, put in fire, short-circuit, connect reversely, solder, 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 the user's manual
(Hardware) of the CPU module used.
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.
[Startup and Maintenance Precautions]
CAUTION
● Do not disassemble or modify the programmable controller. Doing so may cause fire, equipment
failures, or malfunctions.
For repair, consult 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.
Doing so 500 times or more may cause malfunction.
● Turn off the power to the programmable controller before connecting or disconnecting any extension
cable. Failure to do so may cause device failures or malfunctions.
● Turn off the power to the programmable controller 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
● Do not use the chemicals for cleaning.
● If there is the possibility of touching the programmable controller inside a control panel in
maintenance, make sure to discharge to avoid the influence of static electricity.
● Since there are risks such as burn injuries, please do not touch the surface of the equipment with bare
hands when it is operating in an environment which exceeds ambient temperature of 50.
