The engine or other type of prime mover should be equipped with an over speed (over temperature, or overpressure, where applicable) shutdown device(s), that operates totally independently of the prime mover control device(s) to protect against runaway or damage to the engine or other type of prime mover with possible personal injury or loss of life should the mechanical-hydraulic governor(s) or electric control(s), the actuator(s), fuel control(s), the driving mechanism(s), the linkage(s), or the controlled device(s) fail.
CAUTION To prevent damage to a control system that uses an alternator or battery-charging device, make sure the charging device is turned off before disconnecting the battery from the system. Electronic controls contain static-sensitive parts. Observe the following precautions to prevent damage to these parts. z Discharge body static before handling the control (with power to the control turned off, contact a grounded surface and maintain contact while handling the control). z Avoid all plastic, vinyl, and Styrofoam (except antistatic versions) around printed circuit boards. z Do not touch the components or conductors on a printed circuit board with your hands or with conductive devices.
