DSQC611 3HAC13389-2

FAQS

• Which MOTOR ON contactors are associated with ABB DSQC611 3HAC13389-2?
  The contactor arrangement identifies K42 and K43 as the MOTOR ON contactors alongside the board.
• What must happen to X23 plugs when ABB DSQC611 3HAC13389-2 is replaced in the specified SafeMove arrangement?
  Transfer the plugs at pins 1 and 4 to the replacement board; the limit-switch override contact remains plugged and unused.
• What connection detail should be captured before unplugging ABB DSQC611 3HAC13389-2?
  Identify every board connector and its original harness destination before disconnection. Keep the MOTOR ON, brake and applicable X23 connections distinguishable so that reassembly preserves the original circuit allocation.
• Why is ESD protection required while handling ABB DSQC611 3HAC13389-2?
  The circuit board is sensitive to electrostatic discharge, so handling must follow the controller ESD procedure.
• Which brake-related component belongs to the contactor arrangement around ABB DSQC611 3HAC13389-2?
  The arrangement includes a brake contactor in addition to the K42 and K43 MOTOR ON contactors. Preserve the brake-circuit connections independently from the MOTOR ON connections when servicing the assembly.
• Does the MOTOR OFF state make ABB DSQC611 3HAC13389-2 safe to remove?
  No. MOTOR OFF is an operating state, not electrical isolation of the cabinet. Isolate controller main power before removing the contactor-interface board and follow the controller service procedure.
• Should ABB DSQC611 3HAC13389-2 be secured before its board connectors are reattached?
  Yes. Refit the circuit board and its attachment screws before restoring the connectors. Keep each harness on its original connection and maintain ESD protection throughout handling.
• How does cabinet architecture change the service location of ABB DSQC611 3HAC13389-2?
  In a single-cabinet controller, the board is on the left cabinet wall. In the dual-cabinet arrangement, it is on the left wall of the Drive Module. Identify the cabinet architecture before selecting the assembly to service.
