WARNING
Read this entire manual and all other publications pertaining to the work to be performed before install-
ing, operating, or servicing this equipment. Practice all plant and safety instructions and precautions.
Failure to follow instructions can cause personal injury and/or property damage.
The engine, turbine, or other type of prime mover should be equipped with an overspeed (overtempera-
ture, or overpressure, where applicable) shutdown unit(s), that operates totally independently of the
prime mover control unit(s) to protect against runaway or damage to the engine, turbine, or other type
of prime mover with possible personal injury or loss of life should the mechanical-hydraulic gover-
nor(s) or electric control(s), the actuator(s), fuel control(s), the driving mechanism(s), the linkage(s), or
the controlled unit(s) fail.
CAUTION
To prevent damage to a control system that uses an alternator or battery-charging unit, make sure the
charging unit is turned off before disconnecting the battery from the system.
Electronic controls contain static-sensitive parts. Observe the following precautions to prevent dam-
age to these parts.
•
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).
•
Avoid all plastic, vinyl, and Styrofoam (except antistatic versions) around printed circuit boards.
•
Do not touch the components or conductors on a printed circuit board with your hands or with
conductive units.
