TB3-1 TS_21 In
RBM output with integral thermal
warning
Customer use of this auxiliary
contact may include:
• PLC or control string input that
RBM is nearing its thermal
limit

TB3-2 TS_22 Out
TB3-3 CONSTAT_41 In RBM output of a normally closed
contact
(Closed = motor disconnected
from drive)
Customer use of this auxiliary
contact may include:
• PLC input connection,
indicating RBM contactor
status
• Safety relay input for safety
string
• Part of RBM safety string for
mechanical redundancy
TB3-4 CONSTAT_42 Out
TB3-5 SHIELD

TB3-6 COIL_A1 In RBM contactor coil with integral
thermal fault. Applying 24V Coil
Power picks-up the contactor,
which connects drive power to
motor leads (i.e., motor rotates).
Customer use may include:
• Control from a safety relay
output or signal relay output
indicating system is clear for
rotation

1 Connectors are keyed to prevent misconnection of power interface cables to and from the RBM.
2 Ground connection for the motor cable passes through the drive and motor connectors.
Cable shielding must be grounded to the chassis via the spring-loaded cable clamps.
3 I/O Shield terminations are connected internally to chassis ground.
4 Wire supplied by user should be stranded copper with 75° C (167° F) minimum rating. An earth ground connection is required for safe and proper operation. Local agency
rules apply.
5 For additional contactor applications, refer to the Allen-Bradley Safety Product Catalog (Publication S114-CA001A-EN-P).
6 I/O is powered by an external 24V (22.4 - 26.4), 0.5A power supply.
7 Provided by an external 230V (207 - 253), 1A power supply.
