WARNING
Electrical Generating Equipment
Incorrect operation and maintenance can result in severe personal injury or
death.
Read and follow all Safety Precautions, Warnings, and Cautions throughout
this manual and the documentation supplied with the generator set.
Moving Parts Can Cause Severe Personal Injury or Death
• Keep hands, clothing, and jewelry away from moving parts.
• Before starting work on the generator set, disconnect the battery charger from
its AC source, then disconnect the starting batteries using an insulated wrench,
negative (–) cable first. This will prevent accidental starting.
• Make sure that fasteners on the generator set are secure. Tighten supports and
clamps; keep guards in position over fans, drive belts, etc.
• Do not wear loose clothing or jewelry in the vicinity of moving parts or while
working on electrical equipment. Loose clothing and jewelry can become
caught in moving parts.
• If any adjustments must be made while the unit is running, use extreme caution
around hot manifolds, moving parts, etc.
Alternator Operating Areas
WARNING
Ejected Debris
Debris ejected during catastrophic failure can cause serious injury or death
by impact, severing or stabbing.
To prevent injury:
• Keep away from the air inlet and air outlet when the alternator is
running.
• Do not put operator controls near the air inlet and air outlet.
• Do not cause overheating by running the alternator outside rating plate
parameters.
• Do not overload the alternator.
• Do not run an alternator with excessive vibration.
• Do not synchronize parallel alternators outside the specified parameters.
Always wear suitable PPE when working in the hatched areas shown in the diagram
or directly in-line with any air inlet/outlet.
