bypass mode to inverter mode is
0–20 ms. Set this parameter
based on the output interruption
time acceptable to loads.
Max. BPM
transfer times
Cross currents occur during the
transfer between bypass mode
and inverter mode, which
impacts the system. This
parameter specifies the number
of transfers between bypass
mode and inverter mode within 1
hour, which ensures system
security.
