CONNECTIONS
1. Using the four corner tabs OR the DIN rail mounting bracket, mount the Model 601 securely in the
panel. To use the DIN rail bracket, hook the top clip first, then apply downward pressure until the
lower clip "clicks" onto the rail, then stop applying downward pressure.
2. Connect the three-phase power from the line side of the contactor to "L1", "L2" and "L3". First
carefully strip and insert a #12 - #18 AWG wire into the top of the terminal marked L1 and tighten
the screw on the front of the relay. Then, connect the other end of the wire to the line side of the
contactor. Repeat these two steps for L2 and L3.
3. Connect the output relay to the circuitry to be controlled (see Figure No. 1). To control a motor,
connect the normally open contact in series with the magnetic coil of the motor starter as shown.
To sound an alarm, connect the normally closed contact in series with the alarm.
