5.0 Operation

5.1 Display features

5.1.1 On / Test / Alarm disable pushbutton

The On / Test / Alarm disable pushbutton is used to control activation of the UPS and to

energize the load. 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.
