Index

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 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 ±15%) included. E.g.: DC
12V describes a 12V battery whether it is full (13.7V) or flat (10V)

24Vdc—A figure with the unit (Vdc) at the end is a momentary figure with no additional tolerance included.

may, shall, should—Three key words indicating, respectively: flexibility of choice with no implied preference, a mandatory requirement, flexibility of
choice

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 using 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 using diodes or
other switching arrangements. E.g. to achieve a 40A redundant system, five 10A
power supplies are required in a N+1 redundant system.
