To avoid possible personal injury whenever you are working with the SC750 series controller, adhere to the following safety guidelines:
- **Controller Cover and Grounding:**
– Do not power up the controller without the cover on and ensure the chassis is tied to earth ground.
- **Motor Case Grounding:**
– Do not operate the controller without the motor case being tied to earth ground.
- **Internal Circuitry:**
– Do not make any connections to the internal circuitry.
- **Motor Connections:**
– Do not connect or disconnect the motor while power is applied to the unit. Always remove power before making any connections to the unit.
- **Removing the Cover:**
– Before removing the cover of the unit, shut off power and allow the unit to sit for 5 minutes to discharge internal voltages.
- **Motor Terminals:**
– Be cautious of the motor terminals on the drive when disconnected from the motor. With the motor disconnected and power applied to the controller, the motor terminals of the drive can have high voltage present.
- **Safety Shutdown:**
– Do not use the enable input as a safety shutdown. Always remove power to the controller for a safety shutdown.
Following these precautions will help ensure safe operation and maintenance of the SC750 series controller.
