To connect DIN coil:

  1. Remove the Philip screw from the plastic housing and unplug it from the DIN coil.
  2. From the screw opening, use the screw to push the terminal block out of the plastic housing.
  3. Note the 1, 2, and ground markings on the underside of the DIN enclosure.
  4. For DC DIN coil, connect 1 to Positive, 2 to Negative.
  5. For AC DIN coil, connect 1 to HOT wire, 2 to Neutral wire, and if required, connect ground to ground wire.

To connect Grommet coil:

  1. For DC Coil, connect one of the two wires to Positive, and the other wire to Negative.
  2. For AC Coil, connect one of the two wires to HOT wire, and the other wire to Neutral wire.
