The following functions and features can be read and set via
the submenus of the configuration menu:
DEVICE SETUP
Bit rate for the command line interface in communication
ports and the USB-port in the front panel. The front panel
is always using this setting. If SPABUS is selected for the
rear panel port, the bit rate is according SPABUS settings.
Access level [Acc]
LANGUAGE
List of available languages in the relay
CURRENT SCALING
Rated phase CT primary current (Inom)
Rated phase CT secondary current (Isec)

Rated I
01
input of the relay [Ioinp] is 5 A / 1 A or 1 A / 0.2 A.
This is specified in the order code of the device.
The rated input values are usually equal to the rated secondary
value of the CT.
The rated CT secondary may be greater than the rated input
but the continuous current must be less than four times the
rated input. In compensated, high impedance earthed and
isolated networks using cable transformer to measure residual

, it is quite usual to use a relay with 1 A or 0.2 A
input although the CT is 5 A or 1A. This increases the
measurement accuracy.
The rated CT secondary may also be less than the rated input
but the measurement accuracy near zero current will decrease.
VOLTAGE SCALING
Rated Uo VT secondary voltage (Uosec)
