4.11Interconnecting Modular Cabinets

After the Modular Cabinets have been mounted to the wall, the backplanes of the cabinets have to be interconnected using the flat ribbon cable from the interconnection set, NTMNB 101 105 (see Figure 4-9). Install one end of the cable in one of the cabinets. Feed the other end of the cable through the sides of the cabinets and insert it into the connector on the back plane. Make sure the connector’s latch closes.

Ensure that an earth ground has been run to cabinet #1 (see Figure 4-8). Take the green/yellow ground cable from the interconnection set and connect the cable from the ground plate of the first cabinet to the ground plate of the second cabinet. Continue connecting the ground cables to the third and fourth cabinets as they are installed (see Figure 4-9).

The system bus on the backplane is terminated on both sides with R–networks in a SIL socket. When the Modular Cabinets are connected together, R–networks must be present only at both ends of the extended bus (see Figure 4–9).
