The po
wer monitoring device is designed for operation with the following measuring voltages:
Rated voltage
• 57.5/100...400/690V(IEC)
• 57.5/100...347/600V(UL)
NOTICE
Observe limit values
The maximum limits giv
en in t
he technical data or on the rating plate must not be exceeded
even at startup or when testing the device.
