Always test your UPS after installing it. Otherwise, you might be sorry when a power failure happens in your neighborhood!
The larger the load attached to a UPS unit, the shorter the time interval the unit can continue powering attached devices during a power outage. Be sure that your UPS unit can support your power needs for the time needed to properly shut down your system.
