PE is the abbreviation for Protective Earth and has the same meaning as the symbol .
This document uses the term “earth” which is the same as the U.S. term “ground”.
To be defined, value or description will follow later.
A figure displayed with the AC or DC before the value represents a nominal voltage with
standard tolerances (usually ±15%) included.
E.g.: DC 12V describes a 12V battery disregarding whether it is full (13.7V) or flat (10V)
A figure with the unit (Vdc) at the end is a momentary figure without any additional
tolerances included.

Use of two identical power supplies in parallel to provide continued operation following most
failures in a single power supply. The two power supply outputs should be isolated from each
other by utilizing diodes or other switching arrangements. E.g. two 10A power supplies are
needed to achieve a 10A redundant
system.
