To install and interconnect the Eaton IL0131080EN Air Circuit Breaker in a Type 32 interlock configuration, follow these steps:

1. Before starting the installation, ensure that all breakers are in the OPEN and DISCHARGED position.

2. Install the drive arm to the end of the pole shaft using an M3 x 8 mm flathead xxxx . Apply Loctite Blue 242 to ensure the xxxx cannot loosen during operation. Torque to 0.3-0.6 N·m (3-5 in-lb).

3. Install the trip pin to the trip bar using an M3 x 8 mm flathead xxxx . Apply Loctite Blue 242 to ensure the xxxx cannot loosen during operation. Torque to 0.3-0.6 N·m (3-5 in-lb).

4. Fasten the interlock assembly to the drawout cassette's right-side sheet using three M6 x 12 mm hex bolts and lock washers. Torque to 4.5-5.6 N·m (40-50 in-lb). Ensure that the interlock assembly trip paddle is above the trip pin on the trip bar.

5. Fasten four cable brackets to the drawout cassette's right-side sheet just below the interlock assembly using four M6 x 10 mm thread-forming screws. Torque to 7.3-9.6 N·m (65-85 in-lb).

6. Route and install the interconnecting cables according to the recommended cable routing for Type 32 interlock configurations. Ensure that the cables move freely in their cable housings before installation. Attach the cables to the appropriate swivel fittings on the interlock assemblies.

7. Adjust the cables to ensure proper functionality of the cable interlock setup. Use the large bulkhead nuts to adjust the cable housing. Refer to the manual for specific adjustment instructions based on the position of the breakers within the interlock configuration.

8. Perform a functional test of the interlock assembly according to the provided test sequence. Verify that the interlock assembly holds the breakers open or closed as required based on the interconnected breaker states.
