    • Always turn off the power supply before wiring to prevent electric shock.
    • Avoid touching terminals while power is supplied.
    • Use specified crimp terminal sizes (M3.5 screws) and tighten to 1.2 N.m.
    • Ensure proper wiring with adequate rating and twisted wires for reduced electromagnetic interference.
    • Cable used for power connection must have a cross-section of 1mm or greater and insulation capacity of at least 1.5kV.
    • Standard power supply cables are recommended for better anti-noise effect.
    • The equipment is built-in type; terminals may not be accessible after installation.
    • Prevent metal pieces or clippings from entering the product.
    • Install a circuit breaker or mains switch between the power source and supply terminal for easy ON/OFF function.
    • Operate and store the instrument within the specified ambient temperature and humidity ranges.
