  • Page 5: Important Notices On Safety

     FI-915 is designed to draw gases under the atmospheric pressure. If excessive pressure is applied to the gas inlet (GAS IN) and outlet (GAS OUT) of FI-915, measured gases may leak out from its inside and may cause dangerous conditions. Be sure that excessive pressure is not applied to FI-915 while used.

  • Page 6: Precautions

    FI-915 cannot be measured.  Do not use FI-915 near a device that significantly disturbs the waveform of power supply such as electric welder. Also, do not use a power supply of the same system as a device that significantly disturbs the waveform of power supply.

    (A restart may be required to recover from the momentary blackout for 50 msec or more.) To ensure continuous operation and activation, install a UPS outside FI-915. (2) Do not make the power supply line in parallel with another high-voltage/high-current line.

  • Page 17: Protective Grounding

    "b" contact. 3-3-3. Protective grounding For stable operation of FI-915 and safety, it must be connected to a grounding terminal. The grounding wire should be thick and short as much as possible to minimize grounding resistance. Use the EARTH terminal (terminal 3) of the external terminal plate to ground FI-915.

    (8) For safety, to provide a flame arrestor for line, install it into each line of the GAS IN and GAS OUT. CAUTION  FI-915 requires appropriate tubing works (selection of materials and other works) depending on types of sample gas and installation conditions. For questions about tubing works, please contact the distributor .
