Installation Guidelines

Ensure the module is installed in an environment free of aggressive or corrosive gases, as it is only suitable for non-aggressive gas media.
Mount the terminal on a standard 35 mm DIN rail in a position that minimizes external vibration.
Use appropriate pressure tubing compatible with the terminal's pressure connection ports to ensure a leak-free installation.
Maintain ambient conditions between 0 and +55 degC for optimal measurement accuracy.
Adhere to EMC standards EN 61000-6-2/EN 61000-6-4 by ensuring correct grounding of the mounting rail and cabling practices.
