Note: In the models with the 24 Vdc external control power supply
(CFW11...O...W...) pin 13 o XC1 is considered na input, that is, the user
must provide a supply for the inverter (for further details refer to Item 7.1.2
24 Vdc External Control Power Supply on page 7-1). In all the other
models this terminal is an output, i.e., the user has a 24 Vdc power supply
available there
