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”.

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.

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 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, five 10A power supplies are needed in

a N+1 redundant system.
