NVA100X-D - Manual - 02 - 2016
Product identification
Each device is equipped with:
Identifi cation label installed on the front side with following informations: code number, phase and
residual nominal currents, auxiliary voltage range and CE mark
[1]
:
Test label with following informations: data, serial number and test operator signature
[2]
.
Environment
The NVA100X-D device must be employed according to the environment conditions shown (see tech-
nical data).
In case of different environment conditions, appropriate provisions must be provided (conditioning
system, humidity control, etc...).
If contaminants are present (dust, corrosive substances, etc...), fi lters must be provided.
Graphical conventions
The CEI/IEC and ANSI symbols is employed where possible:
e.g.: 51 = ANSI code concerning the overcurrent element.
Following text formats are used:
The ThySetter menu:
Phase overcurrent -50/51
The parameter description (measures, thresholds, operate time,...) and related value:
I> element
Defi nite time
I>def
The display messages (MMI) are shown as:
NVA100X
Notes are highlighted with cursive letters inside colored bar
Note: Useful description note
