Installation & Operating Instructions

Owner’s Reference

PowerPack 1500 MKII

AC Mode
The UPS delivers power to the loads derived from the utility and maintains
proper battery charge. It also regulates the output voltage to within a narrow
range and serves to isolate the load from surges and electrical noise brought by
the utility wiring.

On Battery Mode
The UPS operates on battery when the line voltage or frequency has fallen out-
side the limits. Users are alerted to this mode of operation by visual indicators.
The UPS provides power to the load from the battery and through its inverter
and the output voltage and frequency of the UPS are regulated within a narrow
band.
