Important notes for installation:
• Cables must be fitted through 1/2” NPT cable gland or Atex/IECEx conduit (not supplied withinstrument).
• Make sure after cabling to close tight cover and cable gland, in order to keep IP66 rating (IP65 with option OPV, pressure reliev valve).
• Open cover only after de-energising instrument.
• Attention: check local safety rules and warnings on unit and manual for a correct use of the instrument in hazardous area.
*Operating ambient temperature is defined also according to the options and pressure instrument choosed.
