• To separate or remove the top portion of the terminal block from its base, grasp the top
half and pull apart as shown.
• Each terminal is rated for one 16-12 AWG wire or two 16 AWG wires.
• Torque terminal screws to 5 lb-in (0.5 N•m).
Refer to the torque label on the right inside wall of the unit for load terminal
wire and torque requirements (see Figure 125).
