5.2 UPS Announcements
Before starting UPS, check whether load is proper. The load capacity shouldn't exceed rated
output capacity of UPS to avoid overload protection.
Don't regard ON/OFF button on the UPS panel as the power switch of load. Don't start UPS
frequently.
When UPS works steadily, it can turn on load. Some devices generate large current when startup,
and may lead to overload protection. It is better to start them first. Start the high-power devices
first and then the small-power devices. If you want to close UPS, turn off the load first.
Before starting UPS for the first time, perform checking before power on. If it is ok, power on
UPS. If UPS hasn’t been used for a long time, it need to perform checking before power on.
