Unit Overload - AEG Protect C.R Operating Instructions Manual

5.3.4

Unit overload

The load on the UPS should never exceed the specified rated
load of the unit. If a unit overload occurs nevertheless the
fault LED is turned on accompanied with a signal tone (twice
per second). The connected loads continue to be supplied for
a certain 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.
As a rule, if there has never been an overload during normal
operation, there will not be one during battery operation
either.
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!
The signalling of the red fault LED (ALARM) in
combination with a continuous alarm points out
a switching of fault. Follow the instructions in
chapter 6.
