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.

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.

3AC 400V

A figure displayed with the AC or DC before the value represents a nominal voltage with

standard tolerances (usually ±15%) included. 3AC means three phase input.

E.g.: DC 12V describes a 12V battery disregarding whether it is charged (13.7V) or

discharged (10V)

As long as otherwise stated, 3AC 400V parameters are valid at 50Hz and 3AC 480V

parameters are valid at 60Hz mains frequency.

3x 400Vac

A figure with the unit (Vac) at the end is a value which is used during testing without any

additional tolerances included. 3x 400Vac means a three phase input.

The information presented in this document is believed to be accurate and reliable and may change without notice.
