(approx. 19.5V), this breaker trips automatically.
3. BATT LOW alarm lamp ꞏꞏꞏ This lamp turns on and the buzzer sounds to indicate low voltage
of the battery (approx. 21.5V).
4. CHG alarm lamp ꞏꞏꞏꞏꞏꞏꞏꞏꞏ This lamp turns on (or blinks*) and the buzzer sounds to indicate
any one of the following alarms.
・ The BATT breaker is OFF while the AC breaker is ON.
