PE and symbol PE is the abbreviation for Protective Earth and has the same meaning as the symbol .
Earth, Ground This document uses the term “earth” which is the same as the U.S. term “ground”.
T.b.d. To be dened, value or description will follow later.
DC 24V A gure 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 at (10V)
24Vdc A gure with the unit (Vdc) at the end is a momentary gure without any additional
tolerances included.
may A key word indicating exibility of choice with no implied preference
shall A key word indicating a mandatory requirement
should A key word indicating exibility of choice with a strongly preferred implementation
1+1 Redundancy 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.
N+1 Redundancy Use of three or more identical power
supplies in parallel to provide
continued operation following most
failures in a single power supply. All
power supply outputs should be
isolated from each other by utilizing
diodes or other switching
arrangements. E.g.: To achieve a 40A
redundant system, ve 10A power
supplies are needed in a N+1
redundant system.
