0 1
V0 - V1 - V2 voltage values, three-phase voltages are converted into zero, positive and
negative components. The voltages V0 - V1 - V2 refer to zero, positive and negative
component voltages, respectively. The use of these voltages for short-circuit calculations
increases efficiency.
The display of voltages, phase angles and frequency is shown below.

Thermal Overload

Device protects system within the specified current and time values for the thermal
overload(ANSI 49). The temperature value indicates the temperature sensor data on the
motherboard.
The display of the thermal overload protection is as follows.
