APPENDIX C—EN50160 EVALUATION
This section applies to the following models ACCESS 9360 and it
describes how the ACCESS 9360 operates when the European
standard EN50160 evaluation feature is enabled. For instructions on
how to enable the evaluation feature, see “Setting Up EN50160
Evaluation from the Display” on page 239.
Overview
EN50160:2000 “Voltage characteristics of electricity supplied by
public distribution systems” is a European standard that defines the
quality of the voltage a customer can expect from the electric utility.
Although this is a European standard, it can be applied in the U.S.
The ACCESS 9360 evaluates the following electrical characteristics
in accordance with EN50160:
