Illustration 9.17 Electrical Connections of MCB 113
MCB 113 can be connected to an external 24 V on X58/ in order to ensure galvanic isolation between the VLT
tionDrive and the option card. If galvanic isolation is not needed, the option card can be powered through internal 24 V
from the frequency converter.
NOTICE
It is acceptable to combine 24 V signals with high voltage signals in the relays as long as there is one unused relay in-
between.
To set up MCB 113, use parameter groups 5-1* Digital Inputs, 6-7* Analog Output 3, 6-8* Analog Output 4, 14-8* Options, 5-4*
Relays, and 16-6* Inputs and Outputs.
NOTICE
In parameter group 5-4* Relays, array [2] is relay 3, array [3] is relay 4, array [4] is relay 5, and array [5] is relay 6.
