American Power Conversion 5000VA 5U, 208VAC user manual The UPS is overloaded

PROBLEM AND POSSIBLE	SOLUTION
CAUSE
THE OVERLOAD LED IS ILLUMINATED AND THE UPS EMITS A SUSTAINED ALARM TONE
The UPS is overloaded.	The connected equipment exceeds the specified “maximum load” as defined in
	Specifications at the APC web site, www.apc.com.
	The alarm remains on until the overload is removed. Disconnect nonessential equip-
	ment from the UPS to eliminate the overload.
	The UPS continues to supply power as long as it is online and the circuit breaker
	does not trip; the UPS will not provide power from batteries in the event of a utility
	voltage interruption.
	If a continuous overload occurs while the UPS is on battery, the unit turns off output
	in order to protect the UPS from possible damage.

short beep is emitted every two
seconds to indicate the battery is
disconnected.
Weak battery.	Allow the battery to recharge for 24 hours. Then, perform a self-test. If the problem
	persists after recharging, replace the battery.
Failure of a battery self-test.	The UPS emits short beeps for one minute and the replace battery LED illuminates.
	The UPS repeats the alarm every five hours. Perform the self-test procedure after the
	battery has charged for 24 hours to confirm the replace battery condition. The alarm
	stops and the LED clears if the battery passes the self-test.
