Safety Symbols​

  • Warning: Situations that could cause major or fatal injury to the user.
  • Caution: Situations that may cause minor injury or device damage.

Design Precautions​

Warning​

  • Install a safety circuit to protect the entire control system in case of unexpected power shutdowns or PLC module malfunctions.
  • Use external circuits and switches to safeguard the system from mechanical damage (e.g., emergency stops, limit switches, interlocking circuits).
  • Ensure interlock circuits are configured in the scan program for data exchange or operations by external devices.

Caution​

  • Do not bundle input/output or communication cables with main power cables. Maintain a minimum distance of 100mm (3.94in) to avoid malfunctions.

Mounting Precautions​

Caution​

  • Use the PLC only in environments meeting the specified conditions in the manual. Deviation may cause electric shock, fire, or damage.
  • Ensure all modules are correctly installed. Loose or improper installation may lead to malfunction or failure.
  • Turn off the PLC power supply before mounting modules to prevent electric shock or damage.
  • Close the terminal cover after wiring and before powering on the PLC system.

Wiring Precautions​

Warning​

  • Verify the device’s rated voltage and circuit arrangement before wiring to avoid electric shock or damage.
  • Ensure the terminal cover is closed before turning on the PLC power.

Caution​

  • Tighten screws with standard torque to prevent short circuits, fires, or malfunctions.
  • Ground FG terminals with at least D-type (Class 3) grounding.
  • Prevent wiring debris from entering the module.

Test Run and Repair Precautions​

Warning​

  • Do not touch terminals while power is on to avoid electric shock or malfunctions.
  • Turn off power to the PLC and other systems before cleaning or tightening screws.

Caution​

  • Do not modify or dissociate the PCB from the module casing to prevent fire or malfunctions.
  • Maintain at least 30cm distance from radio, walkie-talkie, or cellphone devices to prevent interference.

Disposal Precautions​

Caution​

  • Dispose of the product according to your country’s regulations for industrial waste. Failure to do so may release toxic substances or cause explosions.
