PE and symbol PE is the abbreviation for P rotective E arth 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 disregarding whether it is full (13.7V) or flat (10V)
24Vdc A figure with the unit (Vdc) at the end is a momentary figure without any additional
tolerances included.
may A key word indicating flexibility of choice with no implied preference
shall A key word indicating a mandatory requirement
should A key word indicating flexibility 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 2.5A power supplies are needed to
achieve a 2.5A 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 10A redundant system, five 2.5A power supplies are needed in
a N+1 redundant system.
