Figure 3.3
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 Adjustable frequency drive. 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 of the Adjustable frequency drive.
If the digital inputs 7, 8 or 9 are to be switched by use of
the internal 24V power supply (terminal 9) the connection
between terminal 1 and 5 which is shown in
Figure 3.4 has
to be established.
