Preface

QUALIFIED PERSONNEL For the purpose of this instruction manual and product labels, a qualified person is one who is familiar with the installation, construction and operation of the equipment and the hazards involved. In addition, he has the following qualifications: Is trained and authorized to energize, de-energize, clear, ground and tag circuits and equipment in accordance with established safety practices. Is trained in the proper care and use of protective equipment in accordance with established safety practices. Is trained in rendering first aid. Typographic and Symbol Conventions The following text formats are used when literal information from the device or to the device appear in the text flow: Parameter names, i.e. designators of configuration or function parameters which may appear word-for-word in the display of the device or on the screen of a personal computer (with operation software DIGSI 4), are marked in bold letters of a monospace type style. Parameter options, i.e. possible settings of text parameters, which may appear word-for-word in the display of the device or on the screen of a personal computer (with operation software DIGSI 4), are written in italic style, additionally. Annunciations, i.e. designators for information, which may be output by the relay or required from other devices or from the switch gear, are marked in a monospace type style in quotation marks. Deviations may be permitted in drawings when the type of designator can be obviously derived from the illustration. The following symbols are used in drawings:Earth fault
