Description Default SettingAvailable Settings
Synchronization Window [Sync Disabled] [±0.5 Hz] [±1.0 Hz] [±1.5 Hz]
[±2.0 Hz] [±2.5 Hz] [±3.0 Hz]
If ±3.0 Hz, on inverter operation the inverter tries to
synchronize with the Bypass when the Bypass
frequency is not more than 3 Hz from the nominal
output frequency; otherwise, the inverter goes to
nominal frequency. On Bypass mode, the sync
window is always ±3 Hz.
NOTE: In Sync Disabled state, if the Bypass
operation is allowed, the UPS synchronizes only
when it is operating on Bypass mode.
