Influence of common mode
voltage
When 600 Vrms is applied between the input terminal and case with the voltage input terminals shorted,
current input terminals open and external current sensor input terminals shorted.
Double the following values when the crest factor is set to 6 or 6A.
• At 50/60 Hz
–80 dB or more (±0.01% of range or less)
• Up to 100 kHz (reference value)
