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

NOTE:

 In Sync Disabled state, if the Bypass

operation is allowed, the UPS synchronizes only
when it is operating on Bypass mode.

If Enabled, unsynchronized transfers to the Bypass
are allowed.

If Disabled, unsynchronized transfers to the Bypass
are not allowed.

NOTE:

 The Qualify Bypass setting may overrule the
