after mounting.
The MCB 113 adds 7 digital inputs, 2 analog outputs and 4 SPDT relays to the standard I/O of the frequency converter which makes it possible to comply

3.1.2. Galvanic Isolation

MCB 113 can be connected to an external 24 V on X58/ in order to ensure galvanic isolation between the VLT AutomationDrive and the option card. If
galvanic isolation is not needed, the option card can be supplied through internal 24 V from the frequency converter - available on X58/ provided that
internal supply is specified in par. 14-80 ([0] No).
