Installation
• Connect an external consumer, e. g. a fan, to one of the two outputs for the power supply with an
appropriate cable (Fig. 3, Pos. 4, 5).
• Select an appropriate country-specific connection cable for the power unit.
– PE plug and IEC connector connection cable (DK 7200.210)
– CMC IEC extension cable (DK 7200.215)
• Insert the cable in the inlet of the power supply of the power unit and to the mains supply (Fig. 3,
Pos. 3).
• Connect the power unit with a CAN bus connection cable to the CMC III PU or to the neighbouring
elements on the CAN bus (Fig. 3, Pos. 6, 7).
Display of the status change:
– The two green and the two red CAN bus LEDs on the CAN bus connection flash.
– The multi-LED of the Processing Unit flashes continually in the green – orange – red sequence.
– The multi-LED of the power unit flashes blue continuously.
• Press the "C" key on the CMC III PU (a first audio signal is issued) and keep it pressed for approx.
3 seconds until a second audio signal is issued.
Display of the status change on the CAN bus LEDs:
– Green LEDs light continuously: CAN bus status "OK".
– Red LEDs light continuously: CAN bus status faulty.
Display of the status change on the multi-LED of the Processing Unit.
– Continuous green light: All units attached to the CAN bus have the "OK" status.
– Continuous orange light: At least one unit attached to the CAN bus has the "warning" status.
– Continuous red light: At least one unit attached to the CAN bus has the "alarm" status.
