Ensure all input devices, output devices, and processes remain in a
safe state upon restoring power. An unsafe state could result in
property damage.
When working on units located in a hazardous area (where explosive
gases may be present), make sure the area is in a non-hazardous state
before performing procedures. Performing these procedures in a
hazardous area could result in personal injury or property damage.
