3.0 Installation 3.7 Test for proper operation - continued cord. Observe that your equipment operates normally during both transfer from utility power to UPS power and back again. Repeat this test four or five times to ensure proper operation. See the 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 the UPS, the UPS’s rear panel circuit breaker may trip. This is called an overload situation. Once the circuit breaker trips, the UPS 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 immediately shut down and cease to power the load. In this case, the UPS will emit a loud tone to alert you of the overload. If this occurs during your test, turn off the UPS and decide which equipment will be left unprotected by the UPS. The circuit breaker may be reset (press button) when the overload is removed. Page 12
