POWERING A 12V DC DEVICE5.
The Portable Power 750 is a power source for all 12 volt DC accessories
that are equipped with a 12V accessory plug. The DC accessory outlet
has a 15-amp automatic overload protection circuit breaker. The breaker
will automatically reset after an overload occurs.
To operate a 12V DC device:
Open the protective cover of the DC power outlet on the right side of the 5.1
Portable Power 750.
Plug the 12V DC device into the DC power outlet, and turn on the 12V DC 5.2
device (if required).
If the 12V DC device draws more than 15A, the internal circuit breaker of 5.3
the Portable Power 750 will momentarily disconnect power to the device.
If this occurs, unplug the device and the circuit breaker will automatically
reset after several seconds.
