Shielded cable*1
*1: The cables connected to the input terminals should be cables or shielded twisted pair cables which can be
connected to temperature sensors, and should be kept separate from other power cables and cables which
may generate noise.
*2: If there is much noise, please connect the terminal FE to the ground terminal.
*3: Please connect FE on a power supply module and the temperature measurement input terminal FE to the
system ground, and then ground the system ground or connect the system ground to a distribution box.
*4: Please do not wire the terminal .
