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 frequency converter. Digital/analogue
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 the digital inputs 7, 8 or 9 are to be switched by use of the internal 24 V power supply (terminal 9) the connection between terminal 1 and 5 which is
illustrated in the drawing has to be established.
