Product Information

The Electrical Interlock (Rev. C) is a safety device designed to prevent electric shock by ensuring that all internal and external electrical and mechanical clearances are checked before energizing any circuits. 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

1. Before installation, ensure that all internal and external electrical and mechanical clearances are checked to ensure safe operation.
2. To install the Electrical Interlock, follow these steps:
3. Remove the cotter pin, shoulder bolts, latch rods, latch, and spacer.
4. Remove the handle by removing the two screws.
5. Choose the appropriate handle and latch kit based on your requirements:
   • Type L1 (padlocking) Handle and Latch Kits
   • Type L2 (key-locking) Handle and Latch Kits
   • Type L3 (non-locking) Handle and Latch Kits
6. 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.
7. For enclosures with doors hinged on the left side, follow the modifications instructions provided in section “Modifications Instructions (Enclosure Doors Hinged on Left Only)”.
8. For enclosures with doors hinged on the right side, follow the modifications instructions provided in section “Modifications Instructions (Enclosure Doors Hinged on Right Only)”.

WARNING
To avoid electric shock, do not energize any circuits before all internal and external electrical and mechanical clearances are checked to assure that all assembled equipment functions safely and properly.

INSTALLATION INSTRUCTION

1. Remove cotter pin, shoulder bolts, latch rods, latch and spacer.
2. Remove handle shown by removing two screws. To remove padlocking handle (not shown), remove three hex nuts, lock washers, and latch rod stop.
3. Place interlock assembly in location and tighten handle screws. Assemble the remaining parts as shown. For padlocking handle (not shown), place interlock assembly on door first. Then place latch rod stop over interlock and fasten with three screws, nuts, and lockwashers. (Reference padlocking handle installation instruction, P/N 87551150) Assemble remainder of parts as shown.
