Remove the terminal block from the power receptacle.2. Verify that the switch is disconnected from the power source.3. Orient the terminal block with upside up and identify the "L", "N", and "PE" connections on theterminal block.If you orient the terminal block upside down, you cannot insert it into the power receptacle.4. As shown by callout 1 in Figure2-7 , insert the AC wires into the terminal block, with the live wire,natural wire, and the PE wire inserted into the "L", "N", and "PE" connections, respectively.5. As shown by callout 2 in Figure2-7 , use a flat-head screwdriver to fasten the screws of theterminal block to secure the wires to the terminal block.The recommended torque is 6 lb.in (0.68 Nm).6.
