6. First connect the ground (green or green/yellow) wire. It must be connected to the
ground block as shown in Figure 2-3, not to "GND" terminal on the connector.
The ground block is located on the wall of the box at top right. To connect to
ground block, strip ground wire about 1/4" (6.4 mm) from end, loosen screw on
block, slide wire in hole, and tighten screw to pin wire in place.
Figure 2-3. Wiring connector and ground block for AC power and stop circuit.
7. Now find the connector TB3 for the other AC wires and stop circuit. It is at top
right. The connector consists of an L-shaped top section and base. Pull the L-
shaped part away from its base. This is the part you will connect wiring to.
NOTE: A ground wire is attached from the connector to a case lug as shown in
Figure 2-3. Leave the ground wire attached to the connector while making
connections. If you remove this wire in order to pull the connector all the way out
of the box, be sure to replace it when done.
8. Connect wires to the L-shaped top section as shown in Figure 2-3. For 115 Vac,
connect black wire to HI slot and white wire to NEU. (For 230 Vac connect black
wire to HI slot and red wire to NEU). To connect a wire, find the correct slot and
loosen the screw over that slot by turning it counterclockwise (see Figure 2-4).
Strip the correct wire for this slot 1/4" (6.4 mm) from end. Insert bare wire into
slot 90% of the way. Tighten the screw. Metal tooth inside slot will clamp down
on the bare wire for a tight connection. Make sure the metal tooth is clamped
down on the bare part of the wire, not on the insulation. If on the insulation, you
will have a bad connection.
Connect both wires and double check connections when done.
NOTE: The connector can only plug in one way. Make sure you don't start at
the wrong end when connecting AC wires. Put the connector over the base the
way it will plug in and note wire marking next to base before starting.
