VLT® 24 V DC Supply MCB 106
VLT® Midi Drive FC 280
The instructions provide information about installing the VLT® 24 V DC Supply MCB 106 on VLT® Midi Drive FC 280.
VLT® 24 V DC Supply MCB 106 is a low voltage supply to the control card. The intended use case is to keep the fieldbus communication of the control card active at all time during a mains power loss or power cycle. It does not enable full operation of the LCP (including the parameter settings) without connection to mains. The specifications of VLT® 24 V DC Supply MCB 106 are described in Table 1.1.

Safety Instructions
WARNING
DISCHARGE TIME
The frequency converter contains DC-link capacitors which can remain charged even when the frequency converter is not powered. High voltage can be present even when the warning LED indicator lights are off. Failure to wait the specified time after power has been removed before performing service or repair work can result in death or serious injury.
•Stop the motor.
•Disconnect AC mains and remote DC-link supplies, including battery back-ups, UPS, and DC-link connections to other frequency converters.
•Disconnect or lock PM motor.
•Wait for the capacitors to discharge fully. The minimum waiting time is specified in Table 1.3.
•Before performing any service or repair work, use an appropriate voltage measuring device to make sure that the capacitors are fully discharged.
