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 coils or
Lead Wire DIN coils:

DC Coil:

1. If the DC solenoid coil has a red and a black wire, connect positive to RED wire and negative to BLACK wire.

2. If the DC solenoid coil has two same color wires, connect positive to one of the two wires and negative to the other wire.

AC Coil:
