An abbreviation is not an acronym. Acronyms are words formed by the first letter or letters of a series of words (these follow regular rules of capitalization if used as the first word of the sentence).
Follow standard rules for common abbreviations (reference the Gregg Reference Manual), but in most cases for Phoenix Contact products or technologies, the abbreviation is capitalized with no punctuation.
Your reader may not know what an abbreviation stands for. in the first instance, spell out the words of an abbreviated phrase, followed by the abbreviation or acronym in parentheses. Abbreviations and acronyms are generally capitalized, but you don’t need to capitalize the words of the phrase itself, unless the origin phrase is a proper noun.
Use downstyle (or sentence case) for headlines/subheads, (except with proper nouns/product names):
Use initial caps for titles of publications, white papers, books, etc.
