cross-section of the cable used must correspond to the maximum connected cross-section but must be at
least 2.5 mm
• Connections are to be established via the screw terminals at the rear panel of the device in accordance with
the circuit diagram. The details on the connection technique for the communication modules on the bottom
of the device (port A and port B) in accordance with the SIPROTEC 4 System Description and the details on
the connection technique for the current and voltage terminals at the rear of the device in the Sections „Con-
nections of the Current Terminals" and „Connections of the Voltage Terminals" must be strictly observed.
