Which two statements are correct for a safe wiring installation to the terminal block of the switch or endpoint? (Choose two.)

A. Insert a green ground wire into the terminal block that is marked RT for return.

B. Verify that DC power is live and within 24 VDC voltage range before starting wiring.
