Note: in the models with the 24 Vdc external control power supply
(CFW11XXXXXOW) the terminal 13 of XC1 becomes an input, i.e., the user
must connect a 24 Vdc power supply for the inverter (refer to the
Safety Stop Function on page
this terminal is an output, i.e., the user has a 24 Vdc power supply available
