Hazardous High Voltage
HIGH VOLTAGE: Motor control equipment and electronic controllers are connected to haz-
ardous line voltages. When servicing drives and electronic controllers, there may be exposed
components with housings 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 compo-
nents. Always work with another person in case an emergency 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.
