10.2.1 Galvanic Isolation in the MCB101
Digital/analog inputs are galvanically isolated from other inputs/outputs on the MCB101 and in the control card of the adjustable frequency drive. Digital/
analog outputs in the MCB101 are galvanically isolated from other inputs/outputs on the MCB101, but not from these on the control card of the drive.
If digital inputs 7, 8 or 9 are to be switched using the internal 24 V power supply (terminal 9), the connection between terminal 1 and 5 illustrated in the
drawing has to be established.
