Rec12-690 Dc — Manual

Always isolate incoming power supplies before installation. Be aware that dangerous residual voltages may remain at the DC bus and brake terminals even when the motor is stopped.

Verify Switching Loop : Ensure that the DC auxiliary switching terminals are properly integrated with the main motor contactor. If the system relies purely on AC-side switching, the brake will take noticeably longer to engage.
