The power inverter is now ready to deliver AC power to your loads. If several loads are to be operated by
the inverter, turn them on separately, after the inverter has been turned on. This will ensure that the
inverter does not have to deliver the starting currents required for all the loads at once.
NOTE: The Power Button turns the control circuit in the inverter on and off. It does not disconnect
power from the inverter.
When the button is in the off position, the inverter draws no current from the battery. When it’s in
the on position, but no power is being supplied to a load, the inverter draws less than 600
milliamperes from the battery. This is low current draw. It would take more than a week to discharge
a 100 ampere-hour battery at this rate depending on the age of the battery.
CHANGING THE LOW VOLTAGE ALARM SETTING
Cobra Pro Power Inverters are equipped with (2) settings to accommodate battery run times for both
professional trucks and other vehicles. From the factory the inverter defaults to a 11.5 Volt Low Voltage
Alarm setting for professional trucks. If using a Cobra Pro Power Inverter with other vehicle types such as
a car, van or RV, run time can be extended by changing the default Low Voltage Alarm to the alternate
setting at 10.5 Volts. Instructions to change the Low Voltage Alarm setting are as follows:
1. Turn Power Inverter on.
2. Press and hold the POWER button for 5 seconds or until Input Voltage LED turns blue.
3. Once blue, the Low Voltage Alarm will be set to 10.5 Volts.
The setting will not change when the inverter is turned off or the battery is disconnected (to go back
to the default 11.5 Volt Low Voltage Alarm Setting, follow steps 1 and 2).
