Gardner Denver INTEGRA AIRSMART EFC99J Operating And Service Manual page 29

Main Starter - This starter is used to provide control and overload protection for the main drive motor.
Wiring diagrams for typical full voltage applications are illustrated on pages 29 thru 49. For Wye Delta
and less starter applications, refer to the wiring diagram included in each control box enclosure.
Overload protection is provided for each motor on full voltage and Wye Delta applications. The overloads
are adjustable and are factory set based on the motor nameplate amps and the instructions located inside
the control box door. Less starter applications utilize a control relay for control of a remote mounted
motor starter (not provided with compressor package).
