UPS
INTERNAL PROTECTIONS
The maximum input current refers to a nominal load (PF = 0,9), to a 346V+ input voltage, and battery charger under a 7A
charge.
SHORT CIRCUIT
BACKFEED
This UPS has an internal device (redundant bypass power supply) which, in case a fault occurs, activates the bypass
automatically, thus maintaining the load powered with no internal protection and with no limit on the power supplied
to the load.
Under such emergency conditions, any disturbance on the input line will affect the load.
Please see the paragraph "Redundant auxiliary power supply for automatic bypass", in the "USE" section.
