Undervoltage Test
After the overvoltage test, the inverter performs the
undervoltage test. During the test sequence, the current
calibration value of the voltage limit applied is shown in
the display of the inverter.
The voltage limit is increased successively until the
disconnection threshold is reached and the inverter
disconnects from the mains.
Once the inverter has disconnected from the mains, the display successively shows the following
values one after the other:
• Disconnection value,
• Calibration value,
• Reaction time,
• Current line voltage.
