The LED bar graph functions as display for UPS
utilisation. The signal goes off during this
operations status every 2 seconds.
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 (from
105% ± 5% of the specified unit rated load) 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.
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 6.
