päälaitteeseen

Päälaitteeseen is a Finnish illative form used to indicate movement toward or attachment to the main equipment in technical language. In Finnish grammar, the illative marks direction into something, and päälaitteeseen is the form used when the main device or system is the destination or point of connection. The term is common in engineering, manufacturing, automation, and information technology contexts.

Usage examples include installation, maintenance, and interconnection tasks. It frequently appears in manuals, schematics, and specifications: for instance, “Kytke anturi päälaitteeseen” (connect the sensor to the main equipment) or “Päälaitteeseen asennettava ohjelmisto” (software to be installed on the main equipment). The phrase can also modify nouns in compound expressions, such as päälaitteeseen liittyvät ohjeet (instructions related to the main equipment).

Relation to other case forms: päälaitteeseen contrasts with päälaitteessa (in the main equipment) and päälaitteesta (from the main equipment). The illative form helps specify the target of actions like connecting, placing, or integrating components within the primary system. In practice, the choice of illative vs other cases depends on the verb and the desired meaning of destination or attachment.
