APC 6000 Connections between Misi boards modular UPSs, Xm Xm Xm Xm Xm Xm, 127 128 129 130 131

Installation (cont.)

Connections between ACPZ boards (frequency converters or parallel UPSs with SSC)

◗these connections are made through the special cables supplied;

◗these connections only concern installations with a Static Switch Cubicle and should be made in addition to the connections between rectifier- inverter cubicles described previously;

◗the ribbon cable from connector XM133 of the ACPZ board of one rectifier-inverter cubicle is connected to one of the connectors XM127 to XM132 of the ACPZ board of the Static Switch Cubicle.

Important:

Outside the cubicles, group the APOZ inter-board and ACPZ inter-board connections with the inter-cubicle auxiliary connections, and separate this assembly from the power cables.

Connections between each rectifier-inverter cubicle and the Static Switch Cubicle (example of 3 parallel UPS rectifier-inverters with SSC)

Connections between MISI boards (modular UPSs)

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;

◗situation with four modular UPS units: see figure 21.
