UPS SUPPLIED BY A GENERATOR
SET
This message informs the user that the
UPS has received the order to limit the
current drawn by the rectifier/charger.
It is displayed when the corresponding
signal is transmitted by the remote
indications board which must be
configured for this function.
THE BATTERY C.B. QF1 IS OPEN,
CHECK THE INSTALLATION
Battery circuit breaker QF1 is open.
The load is no longer protected
because battery power is no longer
available in the event of a normal AC
source outage. The buzzer sounds
continuously.
LOW BATTERY SHUTDOWN
The inverter has shut down at the end
of battery power. The buzzer sounds
continuously.
