Metering, Monitoring, Alarms, And Controls - Toshiba G9000 Specifications

Guide Specification – 3-Phase Static Uninterruptible Power Supply
If the bypass source is beyond the conditions stated below, interrupted transfer shall be
made upon detection of a fault condition.
Bypass voltage greater than + 10%, -10% from the UPS rated output voltage.
Bypass frequency greater than + 1 Hz from the UPS rated output frequency.
5.4.2 Overload Capacity in Bypass:
Continuous duty
Overload duty
5.4.3 Retry function:
When an internal warning has been detected, power flow will automatically switch from
the main circuit (inverter) to the bypass circuit without interruption to the load. If the
internal warning is cleared, UPS will automatically switch the power flow from the
