CAUTION FOR USE ONLY WITH AIR OR COMPATIBLE GASES!
CONTACT FACTORY FOR USE WITH GASES, OTHER THAN AIR AND NITROGEN.

Important notes for installation:
Cables must be fitted through 1/2” NPT cable gland or Atex/IECEX conduit (not supplied with instrument).
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
