  • Page 3: Safety Precautions

    • If the WIL-101-ORP is installed within a control panel, the ambient temperature of the unit – not the ambient temperature of the control panel – must be kept to under 50 . Otherwise the life of electronic parts (especially electrolytic capacitors) of the unit will be shortened.

  • Page 4: Wiring Precautions

    • Do not leave wire remnants in the instrument, as they could cause a fire or a malfunction. • Use a solderless terminal with an insulation sleeve in which the M3 screw fits when wiring the WIL-101-ORP. • Tighten the terminal screw using the specified torque. If excessive force is applied to the screw when tightening, the terminal screw may be damaged.
