Notes:
1> As soon as the UPS is connected to power, the battery begins charging, whatever the On/Off switch
position. When the UPS is operating on battery power, Solution-Pac software will indicate how much
time is left at the current level of load. The indicated time remaining is an approximation based on
several load-power curves.
2> If the utility power failure exceeds the battery backup time, the UPS will shut down to prevent
excessive battery discharge and will restart as soon as utility power returns.
3> After a power outage, when the battery is partially or fully depleted, the indicated time remaining on
battery may not be accurate. Always exercise caution when operating your equipment under these
circumstances until the batteries have had enough time to completely recharge.
4> The overload breaker trips off during a severe overload. If this occurs, unplug excessive loads and
reset circuit breaker by pressing its reset button.
5> Lead-acid batteries operating inside a UPS will last from two to four years before needing
replacement, depending on the environment. Before they quit operating entirely, you should contact
MGE to order replacement batteries. Doing so will greatly increase the likelihood of protecting your
equipment from power black-outs.
