The recommended setting is the current that is usually flowing in the system. If the usual
current is 50 A, set the display range to 50 A. In this case, the current is displayed with one
decimal place.
5.3.2 Additional settings
Language
After initial startup, the language of the text on the display can be set in the
"LANGUAGE/REGIONAL" submenu of the "SETTINGS" menu.
Date/time

the protective mechanisms available in the device are activated.
For further information, please refer to chapter Security features (Page 87).
Please also note the information in chapters Operator control (Page 61) and Parameter
assignment (Page 69).
5.4 Applying the measuring voltage
The power monitoring device is designed for operation with the following measuring
voltages:
Rated voltage
● 57.7/100 … 400/690 V ±20 % (IEC)
● 57.7/100 … 347/600 V ±20 % (UL)
Observe the technical ratings.
The limits given in the technical data or on the rating plate must not be exceeded.
Measurement of DC voltage is not possible.
External voltage transformers are required to measure higher voltages than the permissible
rated input voltages.
