INTENDED USE
The power supply shall only be installed and put into operation by qualified personnel.
This power supply is designed for installation in an enclosure and is intended for the general use, such as in industrial
control, office, communication, and instrumentation equipment. Do not use this device in aircraft, trains and nuclear
equipment, where malfunctioning of the power supply may cause severe personal injury or threaten human life.
TERMINOLOGY AND ABREVIATIONS
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.
AC 230V A figure displayed with the AC or DC before the value represents a nominal voltage with
standard tolerances (usually ±20%) included.
E.g.: DC 12V describes a 12V battery disregarding whether it is full (13.7V) or flat (10V)
As long as not otherwise stated, AC 100V and AC 230V parameters are valid at 50Hz and AC
120V parameters are valid at 60Hz mains frequency.
230Vac A figure with the unit (Vac) at the end is a momentary figure without any additional
tolerances included.
