Wiring Diagram
1. Connect the two wires fom the brake to terminals 5 and 7.
2. Connect the two wires from the clutch to terminals 6 and 7.
3. The switch (furnished by user) is connected between terminals 3 & 5 and 4 & 6 as shown in the connection diagram.
4. Connect the AC input to socket terminals 1 and 2. The "hot line" must be connected to terminal 2. This line measures
120VAC to conduit ground. The "neutral" line (color coded white or natural-gray) is grounded at the 120 VAC supply trans
former and must be connected to terminal 1. This line measures zero VAC to conduit ground. A chassis ground should be
provided as a non-current conducting ground wire (color coded green).
