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
7.1.2 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.
