For the supply circuit (terminals 31, 32) and switching outputs 41, 42, cables suitable for temperatures up to T = 110 °C (230 °F) may be used without restriction. Cables which are only
suitable for temperatures up to T = 80 °C (176 °F) restrict the temperature ranges. These restrictions also apply for the VR model (remote mount design) and the PROFIBUS PA model with
plug connector.
Important
The legibility of the display can be impaired at temperatures < 0 °C (< 32 °F) and > 55 °C (> 131 °F). The functionality
of the meter and the outputs remains unaffected by this. Please refer to the order information for ambient
temperatures < -20 °C (< -4 °F).
Please note the information in the section titled "Technical data for hazardous areas, transmitter".
