3.7 Test for proper operation (continued)

following section covering Overloads if abnormal operation is encountered.

The power I/0 control switches power to your equipment. If you leave your equipment power switches on, the I/0 power control can be used as a master on/ off switch!

3.8 Overloads

If the total power requirement of your equipment is much greater than the capacity of your PowerCell, its rear panel circuit breaker may trip. This is called an overload situation. Once the circuit breaker trips, the PowerCell will attempt to operate the load using its internal power source. This may result in an unexpectedly short run time or, if the overload is severe, the UPS will immedi- ately shut down and cease to power the load. In this case, your PowerCell will emit a loud tone to alert you of the overload. If this occurs during your test, turn off the PowerCell and decide which equipment will be left unprotected by the UPS. The circuit breaker may be reset (press button) when the overload is removed.
