Switch Off,tag, and lockout all AC power to the TLS Console,dispensers and submersible pumps. <br /> 2. Run conduit(s)from the console to the control box or boxes for the STPs that will have PLLD transducers installed. <br /> The conduit must be large enough to fit two#14 AWG wires for each pump control leg you are installing.There are <br /> knockouts for 3/4-inch, 1-inch or P/4-inch conduit in the console. When deciding on the size and number of conduits <br /> required,consider the number of wires entering the console. <br /> 3. Pull two#14 AWG color-coded or marked wires for each PLLD Controller Module between the power bay of the <br /> console and the submersible pump relay control box (Figure 3-2). Since wiring for multiple pump controls may be <br /> entering the console through the same conduit opening,be sure to color code or mark each wire to identify its <br /> source! <br /> IMPORTANT! Dispensers and console must be wired to the same leg of incoming power at the main electrical panel; <br /> otherwise damage may result to dispensers and console. <br /> 3-3 <br />
