Design Guide
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 those on the control card.
If the digital inputs 7, 8 or 9 are to be switched using the
internal 24 V power supply (terminal 9), the connection
between terminals 1 and 5, which is shown in
Illustration 3.2 has to be established.
