– button (disconnection of the PSU during battery-assisted operation)
– pin; activation of the acoustic indication
- indication on
- indication off
– potentiometer, DC voltage adjustment
– fuse in the battery circuit
– AC power input
– DC power battery output
– DC power output (+AUX= +U, -AUX=GND)
open = AC power failure
close = AC power - O.K.
open = failure
close = PSU working correctly - O.K.
open = battery failure
close = battery O.K.
– presence of the AC power
– DC output voltage
– PSU overload
– PSU failure
– battery failure
– EXT IN output's status
– battery charge
– optical indication for activating the over voltage system
