FEATURES
Voltage Indicator. This LCD display also monitors the voltage
being drawn from the battery by the inverter. The voltage is
measured at the Negative and Positive power input terminals on the
inverter. The voltage level reading may be lower than the battery
voltage due to the voltage "drop" that occurs as the battery
voltage runs through the terminal connections and cables.
The inverter is designed to operate with input voltages ranging
from 11 to 15 volts. When the voltage drops below 11 volts DC
an audible alarm will sound. If the voltage drops below 11 volts
DC, the voltage indicator will go out and the inverter will
automatically shut down. The inverter also will shut down
automatically when the input voltage exceeds 15 volts DC.
Despite this "built in" protection, the inverter may be damaged
if the input voltage exceeds 15 volts DC and damage caused by
excess voltage input is not covered under the WHISTLER
warranty.
N N o o t t e e : : In the event of automatic shut down or continuous
audible alarm, turn the inverter OFF (O) until the source of the
related problem has been determined and resolved.
