How to use

Place the UPS on a stable, flat surface near the protected equipment and a mains socket. Connect up to four devices to the AC outlets, plug the UPS into the mains and switch it on to start normal operation.

The UPS will regulate voltage automatically and take over on battery if mains power fails.

Recommendations

To maximise battery life, avoid prolonged deep discharges, periodically run the automatic battery test, and replace the battery when the UPS issues a replacement alarm. Ensure the unit has adequate ventilation and keep it away from heat sources and moisture.
