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 is the same as the converter input
voltage. You must take this into account when configuring the separately driven fan.
