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.

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 ampere-hour battery at this draw rate.

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 300 will light whenever the unit detects excessively high or low input voltage, or begins to overheat.

Power Output

Your CPI 300 will deliver 300 watts continuously. It can deliver 360 watts for about 30 minutes, after which it must cool for about 15 minutes before it can resume operation at 300 watts. (NOTE: the wattage rating applies to resistive loads.)

Input Voltage

Your CPI 300 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 ±

0.3volts. This protects the battery from being over- discharged. The inverter will

restart when the input voltage exceeds 12.0 ± 0.5 volts.

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.
