In the case of a joint distribution box. (circuits with both network as well as UPS
power), you must identify each respective circuit power supply (AC or UPS).
The load of the UPS should not exceed the specified maximum capacity of the
device at any time. If there is a device overload the red LED light will flag a fault
accompanied by an audible warning signal. Depending on the magnitude of the
overload, the supply to the connected consumers remains for an amount of time.
However, the connected load must be reduced immediately.
Failure to action the state “device overload” can lead to a total loss of all UPS
functions!
Do not connect household appliances or machine tools to the UPS.
Do not connect additional loads to the UPS or switch if there is a power failure.
i.e. the UPS is in standby mode!
As a rule, when in normal operation and no overload has occurred, then no
overload should occur in battery usage.
