and reduce conduction and radiation interference generated by the
controller.
Precautions for peripheral device connection of the NICE3000
new
:
■
Do not install the capacitor or surge suppressor on the output side of the controller.
Otherwise, it may cause faults to the controller or damage to the capacitor and
surge suppressor.
■
Inputs/Outputs (main circuit) of the controller contain harmonics, which may
interfere with the communication device connected to the controller. Therefore,
■
