Contactors (DIC, DOC, BC)
Allen-Bradley Bulletin 100 Contactors are provided for all ratings. The
contactors function as follows:
1. Drive-input contactor (DIC) opens and closes input to the drive.
2. Drive-output contactor (DOC) opens and closes the connection between
the drive and the motor.
3. Bypass contactor (BC) opens and closes the connection to line-start the
motor.
Motor Overload Relay (OL)
The motor overload relay is set at the factory to 100% of the drive output current.
In many cases, this setting matches the motor full load amps (FLA). However,
before starting the drive, you should check the setting on the motor overload
relay to assure that it is set properly for your motor.
• For motors with a service factor less than 1.15, set the motor overload
relays to 0.9x motor FLA.
• For motors with a service factor equal to, or greater than 1.15, set the
motor overload relay to the motor FLA.
