How to switch between front and rear connection

There are two means of serial communication available for the relay: the front
connection for SPA bus communication and optional rear communication
modules for communication via the SPA bus, IEC 60870-5-103, MODBUS
(RTU or ASCII) or DNP 3.0 protocol.
If the relay is not provided with an optional rear communication
module, or if the module has been disabled, the front connection
is always active and switching between front and rear
connection is not allowed.
If the optional rear communication module is installed and enabled, the
default setting is the rear connection. Switch between front and rear
connection as follows:
1. Press an arrow button to access the main menu.
2. Use the arrow buttons to select CONFIGURATION\COMMUNICATION
and press . The cursor is at the setting currently in use (REAR
CONNECTION or FRONT CONNECTION).
3. Press to enter the setting mode. The second line starts to flash.
4. Use or to select the wanted setting.
5. Press to confirm the selection.
6. Press to return the display to the idle mode.
