Product Information
The Electrical Interlock (Rev.

It is compatible with doors hinged on either the right or left side and can be used with different types of handle and latch kits.
Product Usage Instructions

- To install the Electrical Interlock, follow these steps:
- Remove the cotter pin, shoulder bolts, latch rods, latch, and spacer.
- Remove the handle by removing the two screws.
- Choose the appropriate handle and latch kit based on your requirements:

- Type L2 (key-locking) Handle and Latch Kits
- Type L3 (non-locking) Handle and Latch Kits
- If installing a Type L2 or L3 handle on a 12 or 10 gauge door (.109-.140 inch thickness), use the provided 10-32x.5 screws and no. 10 lock washers.

external electrical and mechanical clearances are checked to assure that all
assembled equipment functions safely and properly.
