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 Item 7.1.3 Nema1 Degree Protection - Frame Sizes
A, B and C on page 7-3 for more details). In all the other models this terminal is an
output, i.e., the user has a 24 V power supply available there.
