    Notes on Use Notes on Use Follow these precautions to ensure safe operation and to obtain the full benefits of the various func- tions. Operation and Installation environment. This instrument should be installed and operated indoors only, between 0 and 50°C and 80% RH or Do not allow the instrument less.
  • Page 10 Notes on Use To avoid damage to the instrument, protect it from physical shock when transporting and handling. Be especially careful to avoid physical shock from dropping. Do not obstruct the ventilation holes. Ventilation holes for heat radiation are provided on the top and rear panels of the instrument.
  • Page 11 Notes on Use Wiring • A qualified electrician shall perform the wir- ing to prevent electric shock. • Avoid live-line electrical work to prevent electric shock and accidents due to short- circuiting. • When tightening the screws, confirm that all screws are securely tightened. A loose screw may result in module errors, fire, or electric shock.
  • Page 12 Notes on Use • Connect the module to a power source that matches the rating in order to prevent fire. • Ensure that the power supply, input, and output are correctly wired according to the wiring dia- gram. (See the chapter on "Preparations" in the instructions manual for each module.) This will prevent fire, malfunction, and errors.
