6.1.5Unit overload

The load on the UPS should never exceed the specified rated load of the unit. If a unit overload occurs nevertheless (from 105% of the specified unit rated load) then the Fault LED lights up and an acoustic signal sounds (twice per second). The connected loads continue to be supplied for a certain length of time depending on the level of the overload. However, the connected load must be reduced without delay.

Non-observance of the "unit overload" condition may cause the total loss of all UPS functions!

Also avoid short-term unit overloads, which may, for example, occur when connecting a laser printer or laser fax machine. Do not connect any household appliances or machine tools to the UPS.

Never connect or switch on any additional loads to the UPS if there is a mains failure, i.e. if the UPS is working in emergency power mode!

As a rule, if there has never been an overload during normal mode, there will not be one in battery mode either.

When the Fault LED lights up in connection with a continuous acoustic signal, this is an indication of a deactivating fault. Follow the instructions in chapter 0.
