•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. E.g.: DC 12V describes a 12V battery whether it is charged (13.7V) or discharged (10V).
• 230Vac—Afigure with the unit (Vac) at the end is a momentary figure without any additional tolerance included.
• 50Hz vs. 60Hz—Unless otherwise stated, AC 230V parameters are valid at 50Hz mains frequency.
•may—A key word indicating flexibility of choice with no implied preference.
• shall—A key word indicating a mandatory requirement.
•should—A key word indicating flexibility of choice with a strongly preferred implementation.
