4.6 Check Site Wiring Fault indicator - 100, 120 Vac versions Once loads are connected to the UPS and the UPS is turned on, the Site Wiring Fault indicator at the UPS's rear panel should be checked. It will illuminate when the UPS is plugged into an improperly wired wall outlet. Wiring faults detected include missing ground, hot-neutral polarity reversal and overloaded neutral circuit. Note: If the UPS indicates a site wiring fault, a qualified electrician should be summoned to correct the building wiring. 4.7 Switch on load equipment If load equipment switches are left on, the UPS's I/Testpushbutton can be used as master system on/off switch. 4.8 Switch on the UPS The UPS and your loads will become energized when the I/Test pushbutton is held pressed for a second. Once powered, the UPS will initiate a battery test. During the test, the UPS will operate the load from power derived from the battery. This test function ensures that the UPS is working properly and that its battery does not require replacement. In the event the batteries are too weak to support the load during the test, the UPS will immediately return to on-line operation (the load will not be affected). The test is completed when the On Line indicator ceases to blink. Note: If the red Load indicator is illuminated, the UPS is overloaded. Unplug equipment that does not require backing up, such as a printer, and restart the UPS. If the Replace Battery indicator illuminates, recharge the UPS overnight and retest.

Once the UPS is energized, pressing the button will initiate a battery test. This will force the UPS to operate on-battery for a brief time during which the UPS determines the strength of the battery. When the UPS is on-battery, this button may be pressed to silence the utility failure audible warning. 5.1.2 Power standby pushbutton When held pressed for a second, this control will deenergize the UPS and all protected loads. However, operation of the UPS's battery charger is unaffected by this control. 5.1.3 On Line indicator Illumination of the On Line indicator means that the load is being supplied conditioned power derived from the utility service. The indicator blinks during the battery test. 5.1.4 On Battery indicator Illumination of the On Battery indicator means that load has been transferred to power derived from the UPS's battery and that utility voltage is not within normal limits. 5.1.5 Smart Boost indicator Illumination of SmartBoost indicator means that the SmartBoost circuitry has been engaged to compensate for unacceptably low line voltage. The UPS is capable of operating in this mode continuously without draining charge from the battery. 5.1.6 Replace Battery indicator Illumination of the Replace Battery indicator means that the automatic battery test has found that the battery is weak and requires replacement. The indicator is extinguished following a successful battery test. Page 1. 5.0 Operatio. 5.2 Battery capacity bar graph 100% 80% 60% 40% 20% Low battery when blinking The battery capacity bar graph continuously displays the state of battery charge. In the above example, the display shows that 100% of rated battery capacity is available. Where power quality is fair, the UPS will be able to maintain the battery at 100% of rated capacity. In the event of an extended utility failure, the capacity shown will decrease at a rate dependent on the load drawn from the UPS. Large computer loads will cause the battery capacity indication to fall at a faster rate. When low battery conditions are reached, the bottom-most bar will blink. Once normal line voltages are restored, the UPS will recharge the battery and the capacity bar graph will show an increasing number of illuminated bars. 5.3 Output power bar graph Overload 85% 67% 50% 33% 17% The output power bar graph displays the power drawn from the UPS as a percentage of the UPS's full rated capacity. This example shows that the load equipment is drawing between 67% and 85% of the UPS's rated capacity. If this were a 1250VA UPS running a computer load, then the above would correspond to between 840 VA and 1060 VA (590 Watts and 740 Watts at 0.7 power factor). This is a typical installation. When the UPS is loaded such that five bars are illuminated, thoroughly test your complete system to be sure the UPS will not become overloaded. A thorough test includes running backup tape drives, disk drives, etc. If the UPS becomes overloaded, the overload bar will illuminate and the UPS will sound an alarm.
