AEG 10000 Manuale Utente

As a result, the electronics continuously attempt to switch 
back to "online" / normal operating status (e.g. when the 
overload or overtemperature no longer applies). 
The bypass is a mechanical link that switches extremely 
rapidly. It is located between the load and the mains. The 
associated synchronisation unit in the bypass ensures that 
the frequency and phase of the inverter voltage is 
synchronised with the mains.

The LED bar graph functions as display for USP
utilisation. The signal goes off during this
operations status every 2 seconds. 

 

The manual bypass allows maintenance and service 
personnel to work on the PROTECT C. without switching of 
the appliance. 

 

If the mains supply fails if the manual bypass is 
activated, the loads supply fails completely. For 
this reason, it is important to switch as fast as 
possible to normal operation mode. 

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) 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
