observe this may result in destruction of parts of the electronics.
Cable specification
• A normal device cable suffices if only the analog signal is used.
• A shielded cable is recommended for HART
®
communication. Observe grounding
concept of the plant.
• In the case of the DIN rail version, a shielded cable must be used if the sensor cable
length exceeds 30 m (98.4 ft). The use of shielded sensor cables is generally
recommended.
