Relay contact located on ATS48 controller. Located at motor. Jumper if switch not present. Connect control power transformer for 120 V secondary voltage. Use RCR relay logic for 120 V control of the ATS48. For 24 Vdc control, omit the RCR relay logic and wire controls directly to the ATS48 (see DETAIL B).
