								Reports an On Battery state as long as the
On Battery		On Battery	Alarm	NO	NO	NO	YES	battery CB is closed, Input Undervoltage
								alarm exists, and the status bit ON UPS is
								set.
								Battery charge current is 50% above the
								Battery Charge Current Limit for longer than
								5 seconds. The load will be transferred to
Battery		Battery						Bypass. If Bypass is not available the UPS
			Fault	YES	YES	NO	YES	will attempt to run from the battery. If both
Overcharge		Overchg
								battery and bypass are not available, a full
								system shutdown will be initiated. This fault
								will inhibit start-up. Contact Liebert Global

								The bypass frequency is outside the ± 5%
								of the system rating. If the load is on
								bypass the static switch will be shut down
								and power will be lost to the load. If the load
Byp Freq		Bypass						is on UPS, transfer to bypass will be

								fault persists check the bypass source for
								the cause of the frequency irregularity.
								Contact Liebert Global services if you have
								questions.
								With the load on Static Bypass the system
								has determined that at least one phase of
								the Bypass has exceeded the KVA, KW, or
								RMS current vs. Time overload spec. The
Byp ovld		Bypass						Static Bypass switch will be turned of and
		OverLoad	Fault	YES	YES	NO	YES	the system will be shut down. Power to the
Shutdown
		Shutdown						load will be turned off. Remove the excess
								load from the UPS and attempt to re-start. If
								the load is below the rating of the UPS and
								it will not re-start, contact Liebert Global
								Services.
								The power conductors on the bypass line
								are not wired to the UPS in the required
								sequence. This alarm should appear only
Byp Phase		Bypass Phase	Fault	NO	NO	NO	YES	during initial start-up or after a repair to the
Rot Error		Rotation Error						source power system. Disconnect power
								from the bypass line and correct the wiring.
								Liebert Global Services must be present
								during initial start-up of your UPS System.
								The system has detected a failed IGBT.
