The PLC must be grounded (FE terminal).
Failure to do so could result in injury to personnel or causing it to malfunction.
Always use the power supply voltage listed in specifications. Using other voltage may damage the equipment or
present a risk of fire.
The wiring operation should be performed by a qualified personnel.
Failure to do so could result in fire, damage or electric shock.
3. Precautions when using the unit
Do not touch the terminals while the power is on. There is a risk of electric shock.
Appropriate emergency stop circuit, interlock circuitry and similar safety measures should be added to the PLC
system to ensure safety in the event of incorrect, missing or abnormal signals caused by broken signal lines,
momentary power interruptions or other causes. Do not share the power supply of relay output and interlock
circuitry because relay output might not work properly due to switching noise from interlock circuitry.
When performing program change, forced output, RUN, STOP, etc., while the unit is running, be sure to check
system safety carefully. Failure to do so could lead to damage to equipment.
Supply power according to the power–up order.
Failure to do so could lead to damage to equipment or malfunction.
4. Preventive maintenance
Do not connect the (+) and (-)
of the battery in reverse polarity. Do not recharge, disassemble, heat, place in
fire, or short circuit the battery. There is a risk of explosion or fire.
Do not attempt to disassemble, repair or modify any part of the PLC.
Electric shock, malfunction or failure may result.
Turn off power to the PLC before mounting or dismounting the module
Electric shock, malfunction or failure may result.
