Connections between Power Unit ASIC and the Control Unit
The communication connections between the liquid-cooled drive power unit and the control
unit (see Page 6-1) can be established using either the conventional round cable (standard in
chassis CH3, CH4 and CH5) or optical cable (all chassis). Note that for chassis CH61 and
larger, only optical cables can be used.
Connections with Round Cable
The communication connection between the drive power unit and the control unit in chassis
CH3, CH4 and CH5 are primarily made with conventional round cable and D-connectors at
both ends.
Remove the protective cover to reveal the D-connector on the power unit. Connect one end of
the communication cable to the D-connector of the power unit and the other end to the
control unit. If the Optical Cable Adapter Board (see below) sits on the D-connector of the
control unit, you have to remove it first. See Figure 4-18 below.
Connections with Optical Cable
If optical cables are used to link the power unit and the control board, a special Optical Cable
Adapter Board connected to the control board D-connector must be used. To connect the
optical cables to the power unit, you will have to remove the protective cover first. See
Figure 4-18. Connect the optical cables as shown in Figure 4-19. Also see Page 4-10, Control
Unit Mounting Box. The maximum length of the optical cable is 33 feet (10m).
