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 400V

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)

400Vac

A figure with the unit (Vac) at the end is a momentary figure without any additional

tolerances included.

50Hz vs. 60Hz

As long as not otherwise stated, AC 380V and AC 400V parameters are valid at 50Hz and AC

480V parameters are valid at 60Hz mains frequency.

Jan. 2010 / Rev. 1.1 DS-CT5.241-EN

All parameters are specified at 24V, 5A, 400Vac, 25°C ambient and after a 5 minutes run-in time unless otherwise noted.
