LED Alarm

It warns about the imminent inverter stop and the consequent load shutdown as

(red)

result of:

 

The battery is fully discharged and the load cannot be transferred on mains

 

(default parameter = 3 min.).

 

Overtemperature (default = 3 min.) or overload condition (125%-10 min, 150%-1

 

min.) and the load cannot be transferred on mains.

LED Warning

When blinking, it means the UPS is in alert condition with the buzzer sounding.

(yellow)

The yellow LED will remain lit after pressing the key Alarm.

 

It remains lit also when the output switch Q1 is open or battery disconnected.

LED Operation

When lit, it means the UPS is correctly operating and the load is powered by the

(green)

inverter. When blinking, it means SERVICE REQUIRED
