7.2.4 POWER SUPPLIES
OPDE DC-DC requires two auxiliary power supply voltages: one for the power supply of the control (adjustment) side
and driver, and one for the power supply of the cooling fans. The adjustment and driver power supply must be
provided through the removable terminal X3, which is located on the front of OPDE DC-DC. The power supply of the
fans, instead, must be provided through the bulkhead terminals on the bottom side of the converter.

TAB. 13 – Fan terminal
X8 is just the power supply terminal of the fans. To enable the operation of the fans, it is necessary to connect a
voltage of 24V between the terminals 3 and 4 of connector X7 (fig.15 left side).
Using a generic logical output LOx set as "O32 - Enable DC-DC fans" and following the connection of (fig.15 right
side) it is possible to control the switching on of the fans based on the temperature of the heat sink.
