7.1 OPTION KITS
7.1.1 24 Vdc External Control Power Supply
Converters with the following codification: CFW11...O...W...
Converters with this option have a built-in DC/DC converter with a 24 Vdc input that provides adequate outputs
for the control circuit. Therefore, the control circuit power supply will be redundant, i.e., it can be provided either
by a 24 Vdc external power supply (connection as shown in Figure 7.1 on page 7-2) or by the standard internal
switched mode power supply of the converter.
Observe that the converters with the external 24 Vdc power supply option use terminals XC1:11 and 13 as the input
for the external power supply and no longer as an output as in the standard converter Figure 7.1 on page 7-2.
In case of interruption of the external 24 Vdc power supply, the digital inputs/outputs and analog outputs will no
longer be fed, even if the mains power is on. Therefore, it is recommended to keep the 24 Vdc power supply
always connected to the terminals XC1:11 and 13.
The keypad displays warnings indicating the converter status: whether the 24 Vdc power source is connected,
whether the mains power source is connected, etc.
