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
All wiring to the female connector should be done before it is plugged into
the male part and screwed to the case. 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
2
mm (AWG 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
the same terminal, a ferrule must be used, see figure 36. This ferrule, is
applied with the by Phoenix recommended crimping tool.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
