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 operation!
As a rule, if there has never been an overload during normal
operation, there will not be one during battery operation
either.
The signalling of the fault LED in combination
with a continuous alarm points out a switching of
fault. Follow the instructions in chapter 8.2.
