3. Swing down the recessed panel to access Terminal Block TB-2 on the bottom interior

surface of the Control Box shown in Figure 2-6.

NOTE

Use 14 to 18 AWG wire for AC power wiring connections to the

SmartPlate ECS/SP Control Box.

4. Feed the external 120/220 VAC power leads through the cutout labeled “POWER IN” on the

bottom of the Control Box.

5. Connect the LINE, NEUTRAL and GROUND leads to the TB-2 terminals shown in Figure 2-

6. Check the connection of wire #100 on the right side of TB-2 to ensure the power is routed to

the proper connection for the 24 VAC transformer. If the incoming power is 120 VAC/60 Hz,

wire #100 should be connected to the terminal with a black wire and the orange wire should

have nothing connected to its terminal. Conversely, if the incoming power is 220 VAC/50 Hz,

wire #100 should be connected to the terminal with the orange wire and the black wire left

unconnected.
