There is a hidden cost to networked equipment that only shows up at the end of a project: the decommissioning list. Device names to release, addresses to retire, documentation to update — all of it work that a temporary section should never have generated.

What does a temporary section need that a permanent one does not?

An exit that costs nothing. This build produces no fieldbus artefacts because it joins no fieldbus: local I/O and a local/remote switch run the section, the Q4/2 plug handles power, and the integrated 24 V PSU powers the panel. When the contract ends, the drive is unplugged, and the only record that remains is a mechanical drawing. For seasonal lines and trial cells, that absence of paperwork is a feature, not a shortfall.

What does the package cost in capability?

Nothing the section will miss. 5.9 A rated in LO duty and 11.8 A in HO cover real belt loads at 2.2 kW, 200% for 3 s handles the loaded start, the integrated C2 filter keeps emissions in order, and the 425 x 240 x 134 mm FSB housing stays fanless at IP65/66 / UL Type 4X. If the section turns permanent, the network builds of this rating — PROFINET and AS-Interface — drop into the identical housing and plug pattern.
