Ordering Information
7.3.11 VLT
The MCB 113 adds 7 digital inputs, 2 analog outputs, and
4 SPDT relays to the standard I/O of the frequency
converter, providing increased flexibility and compliance
with the German NAMUR NE37 recommendations.
The MCB 113 is a standard C1-option for the Danfoss VLT
AutomationDrive FC 302 and is detected automatically
after mounting.

VLT Parallel Drive Modules
Ensure galvanic isolation between the VLT
tionDrive and the option card MCB 113 by connecting to
an external 24 V on X58/. 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 1 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.
