An Over Voltage Alarm occurs if the Any L-N voltage is greater than this threshold register at any time and is
given in tenths of a volt (1200 = 120�0 Volts)� Default is 200�0 VAC

An Under Voltage Alarm occurs if the Any L-N voltage is less than this threshold register at any time and is
given in tenths of a volt (1200 = 120�0 Volts) Default is 60�0 Volts�

Under Voltage Alarm Threshold Main
Frequency is measured from the phase A voltage input� Range is 40�0-70�0Hz:
This register will read as
0xFFFF if frequencies outside of this range or if sufficient voltage is not present on phase A for an accurate
determination.
