Keep 15 cm (5.9’’) minimum distance between sensor lines and 230 Vac power lines. ELECTRICAL CONNECTION The wiring of the temperature sensor must be in accordance with the overall wiring circuit diagram. The terminals are not polarized. Thus, connecting the wires in reverse will not result in any malfunction. Fig. 2. SF00, SF10, SF20 wiring
