overload present.

7.	OVERLOAD SHUTDOWN	This message informs the operator that the load has been
		transferred to bypass due to an inverter overload.

8.	OUTPUT SWITCH OPEN	This is a status alarm. The output switch must be selected
		‘CLOSED’ at all times except when operating on the Maintenance
		bypass supply.

9.	BYPASS SWITCH OPEN	This is a status alarm. The bypass input switch must be closed all
		the times.

10.	BATTERY C.B. OPEN	This is a status indication only. Note that if the UPS is operating
		with the Battery circuit breaker open, and the mains power fails,
		then the UPS output will also fail together with load power, since
		the inverter has no battery backup.

11.	BATTERY: FUSE FAIL	This problem should be rectified as soon as possible. If the mains
		power fails then the UPS output will also fail together with load
		power, since there is no battery backup.

12.	BATTERY: TEST FAILED	The system has carried out a test of the battery. If this alarm is not
		accompanied by a [BATTERY C.B. OPEN] or [BATTERY: FUSE FAIL]
		message then a full check of the Battery bank is required.

13.	DC BUS: UNDERVOLTAGE	When the inverter is operating on the battery this message is
		displayed on the condition when battery voltage has fallen below a
		preset value. If the input a.c. power cannot be restored, you should
		shut down your loads.
