Troubleshooting
UPS Running on AC Power with Audible Alarm
NOTE
This case is transitory. If the overload condition persists indefinitely, it is
always followed by an overload shutdown (see “Case 10 (Normal or Abnormal)
— Overload or EPO Shutdown”) and then, if the AC input is gone or
out-of-spec for a sufficient time, the UPS switches to Sleep mode (see “Case 15
(Normal or Abnormal) — UPS Off or Asleep”). The duration of the overload
warning is inversely related to the degree of overload: the greater the
overload, the shorter the duration of the warning, and vice versa.
Action
1. Power-off the protected equipment, one-by-one, until the UPS returns
to normal operation.
2. Move the input connections of the equipment that was powered-off in
step 1 to another power source.
NOTE
For information on adjusting the load size, refer to “Sizing the Load”. Call HP
Service if you need assistance in resizing the load.
