3. Connect adapter boards to the main board using ribbon
cable (Figure 8). Ribbon cables are keyed to ensure proper
installation.
Orient cables so that the red stripe is on the left.
NOTE: Flat and round ribbon cables are available.
See recommended accessories.
4. Connect current sensors to the terminals on the adapter
boards (Figure 8).
