3.3 Wiring details 3.3.1 Power supply Please read the safety information and the wiring notes before proceeding with the installation of the controller. The controller provides switching power supply with multiple isolation and internal PTC • Nominal voltage 100 - 240V~ (-15% +10%) Frequency 50/60Hz • Power consumption 1.6 W max 3.3.2 PV control unit A For L-J-K-S-T thermocouple type • Connect the wires with the polarity as shown • Always use compensation cable of the correct type for the thermocouple used • The shield, if present, must be connected to a proper earth B For Pt100 temperature sensor • If a 3 wire system is used, always use cables of the same diameter (1 mm 2 min.) (line 20 W/lead maximum resistance) • when using a 2 wire system, always use cables of the same diameter 1mm 2 (AWG 18) and link terminals 5 and 6 C For DT (2xRTD Pt100) Special When the distance between the controller and the sensor and the sensor is 15 m, using a cable of 1mm 2 (AWG 18) diameter, produces an error on the measure of 1°C R1 + R2 must be
