be exposed components with housing or protrusions at or above line potential.
Extreme care should be taken to protect against shock.
Stand on an insulating pad and make it a habit to use only one hand when
checking components. Always work with another person in case an emer-
gency occurs. Disconnect power before checking controllers or performing
maintenance. Be sure equipment is properly grounded. Wear safety glasses
whenever working on electronic controllers or rotating machinery.
