Galvanic isolation in the MCB 101
Digital/analog inputs are galvanically isolated from other
inputs/outputs on the MCB 101 and in the control card of
the frequency converter. 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 frequency converter.
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 shown in Illustration 3.4
has to be established.
