Adapting the analog inputs and outputs
If the setting ranges of the analog inputs and outputs are to be changed, the associated
interface converters (-T401 / -T402 / -T403) must be set. The corresponding interface
converter must be removed for this purpose and the rotary switch on the side ("S1") turned
to the corresponding position.

Separate 24 V DC power supply for NAMUR (option B02)
Description
If the customer cannot provide a separate 24 V DC supply (PELV), this option enables a
second power supply to be installed to provide the PELV (terminal assignment as option
B00, 24 V infeed at terminal -X1:1,2,3 no longer needed).
4.11.33
Outgoing section for external auxiliary equipment for NAMUR (option B03)
Description
If power is to be supplied to a motor fan on site, option B03 provides an uncontrolled fuse-
protected (10 A) outgoing section. As soon as the supply voltage is present at the converter
input, it is also present at these terminals. The voltage corresponds to the converter input
voltage. You must take this into account when configuring the separately driven fan.
