
Routing power and ground from the main disconnect to the scoreboard power and
signal termination points;

Connecting the scoreboard ground to a grounding electrode at the scoreboard location;

Routing control signal cable from the control location to the scoreboard location;

Routing power and control signal cable into the initial module; and

Making connections to the adjoining modules.
These steps are described in greater detail in the following sections.
