INPUT VOLTAGE/AUTO SHUTDOWN
On/Off Switch
The ON/OFF switch turns the control circuit in the inverter on and off. It DOES NOT disconnect power from the inverter.

Output
ON
When the switch is in the OFF position, the inverter draws no current from the battery. When it is the in ON position, but no power is being supplied to the load, the inverter draws less than
500 milliamperes from the battery. This is low current draw. It would take more than a week to discharge a 100
You don’t have to worry about excessive drain on a battery if you leave the inverter switched on for a few days. However, you should switch it off if you are not planning to recharge the battery within about a week.
Fault Indicator
The "fault" indicator of your CPI 150 will light whenever the unit detects excessively high or low input voltage, or begins to overheat.

Power Output
Your CPI 150 will deliver 150 watts continuously. It can deliver 180 watts for about 30 minutes, after which it must cool for about 15 minutes before it can resume operation at 150 watts. (NOTE: the wattage rating applies to resistive loads.)
Input Voltage
Your CPI 150 will operate from input voltage ranging from 10 to 15 volts. Optimum performance occurs when the voltage is between 12 and 14 volts.
If the voltage drops below
10.7± 0.3 volts, an audible low battery alarm will sound. The inverter will automatically shut down if the input voltage drops below
10.0± 0.3 volts. This protects the battery from being
0.5volts.
The inverter will also shut down if the input voltage increases to 15.0 ± 0.5 volts. This helps protect the unit from damage due to excessive input voltage. Although the inverter is protected in this way, it may still be damaged should the input voltage exceed 16 volts.
Automatic Shutdown
The unit will automatically go into thermal shutdown if it becomes overheated due to excessive input voltage, poor circulation or high ambient temperature.
