• Connections are realized via the plug or screw terminals on the rear side of the device according to the circuit
diagram. When using forked lugs for screw terminals or in case of direct connections, the screws must be
screwed in so far that the screw heads align with the terminal block before inserting the lugs and wires. A
ring lug must be centered in the connection chamber in such a way that the screw thread fits in the hole of
the lug. The SIPROTEC System Description provides information regarding maximum wire size, torque,
bending radius and cable relief and must be observed.
