3.2.2 Field bus customer units
To connect field bus systems (incl. some I/O control signal terminals) to the SK 700E frequency
inverters, 4 different field bus customer units are offered. In contrast, the SK 5xxE series of frequency
inverters by default comes with respective onboard terminals to connect some field bus systems and
some I/O control signals. Please heed the differing terminal numbers/terminal names (e.g.
terminal 42 / VO 15V, terminal 44 / VI 24V or VO 24V) for the different power supplies of inputs and
outputs of the SK 5xxE frequency inverter types or sizes.
