Warning
Electric Shock Hazard
To allow stored energy to dissipate after power is disconnected, wait at
least five minutes before replacing parts.
Precaution
The generator contains electrostatic-sensitive components. When repairing the generator, work at
a static-control workstation. Wear a grounding strap when handling electrostatic-sensitive
components, except when working on an energized generator. Handle circuit boards by their
nonconductive edges. Use an antistatic container for transport of electrostatic-sensitive
components and circuit boards.
Notice
Calibrate the generator after you install a new Control board. Otherwise, the default calibration
values are used. Refer to
