24 Vdc power supply 24 Vdc power supply, ±8 %.
Capacity: 500 mA.
Note: In the models with the 24 Vdc external control power supply
(CFW11XXXXXXOW) the terminal 13 of XC1 becomes an input, i.e., the
user must connect a 24 V power supply for the inverter (refer to the section
7.1.4 for more details). In all the other models this terminal is an output,
i.e., the user has a 24 Vdc power supply available there.

3.2.5 Control Connections
The control connections (analog inputs/outputs, digital inputs/outputs), shall be performed in connector XC1
of the CC11 control board.
Functions and typical connections are presented in figures 3.18 (a) and (b).
