Since the voltage output (control output) is not electrically insulated from the internal wiring, one or other of
the control output terminals must be left unearthed when using an earthed thermocouple thermometer. (Con-
nection makes measurements unreliable due to sneak currents.)
To comply with EMC standards, the length of the cable connecting the analog input or universal TC/Pt input
sensor must be 30 m or less. If the cable is longer than 30 m, the EMC standards will not be satisfied.
