Secondary Address Selector

The secondary address selector enables the address of the secondary panel to be set. A dial switch on the face of the selector is labeled 0–7, with each number representing a unique address. Address 0 is reserved for the primary panelboard. If the power supply or controller is plugged into any control bus on the subnet, address 0 should not be used as a secondary address.

Only two control buses may be connected to a secondary address selector. If a second control bus is located in the same secondary panelboard, a secondary bus interconnect cable is required for connecting the secondary address selector to the second bus. For proper operation of the system, always install the secondary address selector on the left control bus. Each secondary address selector must also have its own unique address. If two or more selectors contain the same address, improper operation may result.
