Special Conditions for Safe Use (“X”):
If the temperature sensor connected to the input circuit does not tolerate
an alternating tension of 500V for 60 seconds, the certified transducers
must be powered by galvanically-insulated equipment. Model 444RL
temperature transducers must be connected to associated electronic
equipment certified to EN 50.014/EN 50.020 standards.
