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.
