Power Precautions

First section should contain shared notices for all devices
Danger: Make sure that the power source circuits are properly grounded.
Danger: Make sure you use a power cord displaying the mark of the safety agency that defines the regulations for power cords in your country. The mark is your assurance that the power cord can be used safely with the device.
Danger: To reduce the risk of electric shock, disconnect all power cords before servicing.
Danger: Disconnect the power cord from all power sources to completely remove power from the device.
Danger: To avoid high voltage shock, do not open the device while the power is on.
Danger: Batteries used for RTC/NVRAM backup are not located in operator-access areas. There is a risk of explosion if a battery is replaced by an incorrect type. Dispose of used components with batteries according to local ordinance and regulations.
Caution: Ensure that the device does not overload the power circuits, wiring, and over-current protection. To determine the possibility of overloading the supply circuits, add the ampere (amp) ratings of all devices installed on the same circuit as the device. Compare this total with the rating limit for the circuit. The maximum ampere ratings are usually printed on the devices near the input power connectors.

subsequent sections to contain device-specific notices. Then conditonalize these sections or individual notices.
