Section 6
Connecting
If the IED is equipped with a test-switch of type RTXP 24, COMBIFLEX wires with 20 A sockets,
1.5mm² (AWG16) conductor area must be used to connect the auxiliary power.
Procedure
1. Connect signals to the female connector
The conductors can be of rigid type (solid, stranded) or of flexible type.
The female connectors accept conductors with a cross section area of 0.2-2.5 mm
24-14). If two conductors are used in the same terminal, the maximum permissible cross
section area is 0.2-1 mm
If two conductors, each with area 1.5 mm
terminal, a ferrule must be used, see figure 31. Crimp this ferrule properly to the wire using
tools as recommended by the supplier of the ferrules (keep stripping length of the cable to
minimum 10 mm). The fastening screw shall be tightened with a torque of 0.4 Nm (This
torque applies to all binary connectors).
2. Plug the female connector to the corresponding back-side mounted male connector
3. Lock the female connector by fastening the lock screws
