by hand without effort.
Final checks of the motor
• Check the mounting and fastening of the motor and control
unit. Make sure the motor and the control unit are securely
attached together and mounted tightly in the system.
• Check the control unit connectors. Inspect for shorts, de-
tached wiring, or loose connections
• Check the motor and verify the rotation of the driven load.
Make sure it spins freely by hand in both directions without
effort or assisted means.
