Handling Precautions
• If the sampling cycle is 10 ms, or if CT input or VT input is used, set the power
supply frequency for the region where the product will be used. If a different
power supply frequency is set, the specifications for analog input indication
accuracy may not be satisfied.
• It is not necessary to set the power supply frequency if the sampling cycle is
not 10 ms, or if CT input and VT input are not used.
