CAUTION USE ONLY WITH AIR OR COMPATIBLE GAS!
CONTACT THE FACTORY FOR USE WITH GAS OTHER THAN AIR OR NITROGEN.
Important Notes for Installation:

• Cables must pass through 1/2” NPT Atex cable gland or Atex/IECEx conduit (not included with instrument).
• After connection, make sure to tighten the cable gland and the housing cover to continue to ensure IP66 sealing (IP 65 if with vent valve).
• Open the case only after having disconnected the power supply to the instrument.
• Warning: Check local regulations and warnings on the instrument and in the operating manual for correct use in classified areas.

* Operating ambient temperature is however also determined by the limits of the options and/or the measuring element.
