Note 1: The supply voltage (i.e., 100 to 240 VAC or 24 VAC/VDC) depends on the model. Be sure to specify the required
             type when ordering.
         2: The Controller is equipped with multiple sensor input. Temperature input or analog input can be selected with the
              input type setting switch. There is basic insulation between power supply and input terminals, power supply and
              output terminals, and input and output terminals.
         3: Do not use an inverter output as the power supply. (Refer to Safety Precautions for All E5[]R Models.)
