10.5 OVERLOAD.
The UPS can power loads up to the power rating declared on the machine’s data plate; once this limit is exceeded,
the machine goes into overload condition. Overloads are signalled by a rapid sounding acoustic alarm .
WARNING!
Signicant overloads could cause permanent damage to the UPS!
Avoid connecting laser printers that generate absorption peaks liable to cause overloads on the UPS.
10.6 SELF TEST.
In Normal Mode, when the button is pressed for more than ve seconds, a procedure is run to check battery and
inverter operation.
If everything is working properly, the UPS automatically returns to Normal Mode; if not the test is suspended and the
battery failure is reported through the Battery failure LED .
If the test fails, however, it is recommended that you leave the battery to charge overnight and repeat the test the next
day.
It is advisable to perform the test with the batteries fully charged (LED bar fully lit up).
