IMPORTANT: The measuring
equipment used in troubleshooting
this equipment should be of
industrial quality and should have
the sensitivity to measure electronic
values to the third decimal. Its
accuracy should conform with
acceptable industry tolerances.
Ensure that all specified tools
and/or equipment are available
before attempting to troubleshoot.
Generators produce powerful
voltages. Failure to isolate
generator from power utility can
result in death or injury to electric
utility workers due to
backfeed of electrical energy.
• When testing generators used for backup
power, notify utility company
.
DANGER
Physical contact with energized
electrical components will result
in dangerous and possibly fatal
electrical shock
•
Do not touch bare wires or
receptacles.
CAUTION
These wiring diagrams and
schematics are intended for use
by trained and qualified electrical
service technicians who are
working in a properly equipped
service environment. Familiarity
with the proper method of using
