and outputs of the VLT AQUA Drive.
Contents: MCB 101 must be fitted into slot B in the VLT AQUA

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 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.
