Typographical and
symbol
conventions
The following text formats are used when literal information from the device or to the
device appear in the text flow:
3DUDPHWHUQDPHV, 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 DIGSI 3), are marked in bold letters of a monospace type style.
3DUDPHWHURSWLRQV, 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 DIGSI 3), are written in italic style, additionally. This applies also for options in
menus.
“$QQXQFLDWLRQV”, 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 quotes.
Deviations may bepermitted in drawings when the type ofdesignator can be obviously
derived from the illustration.
The other symbols used are mainly taken from the standards IEC 60617–12 and
IEC 60617–13, or derived from them.
