3.6 AUX Port
The AUX Port is a communication port specially designed for
industrial network communication. The AUX Port connector is
a 9-pin sub-D type. The functionality of the AUX Port depends
on the optional communication module which is plugged into
the unit, e.g. FEDZ-IET.
Please note
The pin assignment of the Aux Port connector is described
in the manual of the communication module.
The procedure for fitting the communication modules is the
following:
1. Turn off the FED.
2. Use a screwdriver to loosen the two screws in the cover.
The screws are marked with ’A’ in Fig. 3/10.
3. Plug the module in the red connectors; make sure the
connectors are locked.
4. Replace the rear cover.
5. Stick the label describing the functionality of the AUX Port
in the area ’B’. The label is supplied with the modules.
