the connections between the Control Unit UC11RB and the PUs (Connectors DB25 XC40 and Fiber Optics),
power connections of the PUs (DC+, DC-, U, V, W and GND), and auxiliary power supply connections of the
cooling (220 V), of the UP11 (24 Vdc) and of the UC11 (24 Vdc). For a reduced number of UP11, connect them
in increasing order (1, 2, 3, etc.), leaving the last positions without connection. This diagram is valid for both
air-cooled UP11 G2 and water-cooled UP11W G2, except for the XC33 connector (fan connection), which does
not exist on the UP11W G2.
