Undervoltage Test

The undervoltage test follows the overvoltage test and the
inverter issues the adjacent display message for
5 seconds.
During the test sequence, the voltage limit applied is
shown in the display of the inverter. The voltage limit is
increased successively until the shut‑down threshold is
reached and the inverter disconnects from the power
distribution grid.
Once the inverter has disconnected from the power distribution grid, the display successively shows
each of the following values one after the other for 10 seconds:

• Disconnection value,

• Calibration value,

• Reaction time.

The change between the first and second display takes places every 2.5 seconds.
