Hazardous High Voltage
WARNING
Motor control equipment and electronic controllers are connected to hazardous 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 components.
●
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.
