OPERATION

The UPS loads may be controlled by the UPS power switch. Since the UPS powers up in the Inverter mode, a functional test is provided every time it is turned on (or the TEST Button is pushed). The battery charger operates with the power switch on or off.

If a low voltage condition (brownout), power outage or over-voltage occurs, the UPS will switch to the Inverter mode, and the AC Normal LED will go out. The Backup LED and Alarm will operate briefly after about 25 seconds, and then every 15 seconds. For long duration power outages, a Low Battery Warning is provided about two minutes prior to low battery shutdown. The LED and Alarm will operate every two seconds. At low battery shutdown the UPS will shut off automatically to protect the internal batteries form excessive discharge. All LED's, alarm and output power will be turned off. When commercial power returns, the UPS will return to the AC Normal mode; the Fault LED and Alarm will operate continuously. Press the Test Button to effect an inverter test and silence the alarm.

During normal AC mode function, the UPS will quietly protect the load from power surges, voltage spikes and noise interference. Commercial power outages are usually of a short duration; thus sounding of the alarm is delayed so as not to be a nuisance.

If the low voltage condition above can be corrected by the boost winding in all models except A300 and A425, the Boost LED will light, signifying the Boost mode is operative and the output voltage has been corrected.

SYSTEM BATTERIES

The internal batteries used in the MINUTEMAN ALLIANCE UPS UNITS are sealed maintenance- free, lead-acid batteries with electrolyte totally absorbed in the plates and separator material. For maximum battery like, temperature should be kept as cool as practical indoors, and at proper trickle charge voltage. Expected battery life is 3 to 6 years at 85ºF. For optimum performance, batteries should be replaced after about 3 years. Replacement batteries can be purchased from Para Systems or from your local distributor or dealer. If the UPS is to be stored, allow the batteries to fully charge for 24 hours; then store in a cool, dry location. For extended storage, recharge the UPS batteries for 24 hours every 4 months.

When the batteries are replaced, provide the used batteries to recycler for proper disposal and reclamation of the lead.

BATTERY/SYSTEM CHECKOUT

To verify proper system function and battery condition, the user is encouraged to engage the test switch periodically. Normal indications as specified should be observed. If the system goes immediately to the low battery warning mode, the batteries should be replaced.
