These low-volume industrial control panels are often a kick in the pants.

Note that:

• R=Red, Y=Yellow, B=Blue. Unless the product emits/extrudes a substance in one of three primary colors (like a Play-Doh Barber Shop), I don’t think this is enough information.
• “Star” and “Delta” aren’t very informative.
• Alignment is consistently janky.
• “Relay Rang” is either a typo or we simply ran out of space for characters.
• Capitalization and punctuation of abbreviations are willy-nilly.
• Something about it is potentially deadly.
