Earth, Ground
This document uses the term “earth” which is the same as the U.S. term “ground”.
T.b.d.
To be defined, value or description will follow later.
DC 24V
A figure displayed with the AC or DC before the value represents a nominal voltage with
standard tolerances (usually ±20%) included.
E.g.: DC 12V describes a 12V battery disregarding whether it is full (13.7V) or flat (10V)
24Vac
A figure with the unit (Vac) at the end is a momentary figure without any additional
tolerances included.
