Caution
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.
