Galvanic Isolation In The MCB 101
Digital/analog inputs are galvanically isolated from other inputs/outputs on the MCB 101 and in the con-
trol card of the drive. Digital/analog outputs in the MCB 101 are galvanically isolated from other inputs/
outputs on the MCB 101, 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.
