Carson CP-12 Series - User Manual

The Carson CP-12/16/24 Series Power Pack System is a versatile device designed to convert 120 VAC line power to 12 VDC for operating various lights, pumps, fans, and other 12-volt devices in recreational vehicles (RVs). It serves as both a 120 VAC Load Center and a 12 VDC Power Converter. It is explicitly stated that this system is NOT SUITABLE FOR BATTERY CHARGING.

Function Description:

The primary function of the Power Pack System is to provide a stable 12 VDC power source from a standard 120 VAC input. It integrates several protective features, including AC circuit breaker(s) for appliance and receptacle overload protection, and a Ground Fault Circuit Interrupter (GFCI) for personal protection against shock hazards. Additionally, it incorporates protection against DC overloads and high temperatures. A key feature is the ability to switch between operating DC devices from the internal converter or a standard 12-volt deep-cycle battery.

Usage Features:

Operation (CP-12/16 Series):

To operate DC devices from the converter, connect the shore-line cord to an appropriate AC source, then manually switch the unit to the "Converter" position. If a battery is installed, DC devices can also be operated by manually switching the unit to "Battery". When the RV is not in use, the unit should be manually switched to "Off" to prevent accidental discharge of the battery.

Operation (CP-24 Series):

For DC device operation from the converter, connect the shore-line cord to an appropriate AC source. The converter will automatically connect the devices to the converter. If AC power is unavailable, DC devices will operate from a battery, if installed. To prevent accidental discharge of the battery when the RV is not in use, the battery should be disconnected.

AC Circuit Breaker(s):

A magnetic circuit breaker provides overload protection for AC devices. If a device or appliance fails, the circuit may be overloaded. To reset, switch the breaker "off" and then back "on". If a "T" option is installed, two circuit breakers are available, with the converter internally connected to the 15 amp breaker. The circuit breaker(s) can also function as a switch to turn AC power and converter power on/off.

DC Circuit Fuses:

These fuses provide overload protection for the DC wiring system. After correcting the cause of an overload, replace the fuse with an automotive-style fuse of the proper rating, as indicated on the front of the converter. Only properly rated fuses should be used.

Ground Fault Circuit Interrupter (GFCI):

The GFCI protects against faulty wiring or accidental contact with AC power. If all AC and DC devices are inoperative, check the GFCI by pressing the "Reset" button; it should "trip". Reset the device as described above. Monthly testing of the GFCI is recommended. If the GFCI fails the test, disconnect the shore-line cord from power immediately, as using a faulty GFCI can lead to injury or death. The GFCI can also be "tripped" by pressing the "Test" button to turn off all power output on the "R" and "S" option Power Pack Systems.

Important Considerations:

• The pulsating DC output of the Power Pack System is unfiltered and not suitable for some 12VDC electronic devices like stereos, LP gas detectors, carbon monoxide detectors, AM/FM/TV signal amplifiers, and 12-volt televisions. These devices should be connected directly to the RV battery. RV refrigerators with 12-volt elements should also be connected directly to the RV battery.
• This system does not provide RV deep-cycle battery charging capabilities. If an RV battery is installed, it can be charged by a commonly available battery charger or by a tow vehicle (if appropriately wired). A charger is available to allow charging from the converter output.
• If a battery is installed, it should be disconnected when the RV is not used for extended periods to prevent accidental discharge. Removing the DC fuses can also help. For maximum battery life, always store the battery fully charged in a cool, dry location, not on concrete, and follow the battery manufacturer's recommendations.

Maintenance Features:

Care/Tips:

• To prevent excessive wear to the GFCI and power relay contacts due to power surges, turn off or unplug AC appliances before connecting the shore-line cord to an AC source.
• Similarly, turn off or unplug AC appliances during electrical (lightning) storms and thunderstorms to prevent excessive wear to the GFCI and power relay contacts from power surges or interruptions. For complete protection, disconnect the shore-line cord during these storms.
