See figures 19 to 21.
◗these connections are made using the special cables (A) supplied;
◗connectors XM5, XM6 and XM7 on the MISI board are used to transmit signals;
◗connectors XM10, XM11 and XM12 on the MISI board are used to receive signals;
◗connector XM5 is associated with connector XM10 for communication with a second UPS unit; similarly, XM6 is associated with connector XM11 for communication with a third UPS unit and XM7 is associated with connector XM12 for communication with a forth UPS unit;
◗situation with two modular UPS units: see figure 19;
◗situation with three modular UPS units: see figure 20;
