How to Install the Sequestr External Disconnect Enclosure

This guide provides step-by-step instructions for installing the Sequestr External Disconnect Enclosure to a control enclosure, ensuring proper mounting and wiring.

Estimated time: 1h

Tools needed:

Screwdriver, Drill, Volt meter, Wire strippers

Supplies needed:

Mounting screws, Terminal connectors, Hoffman hole seal, Hoffman blank adapter plate

  1. Power Down the System

    Turn off the local disconnect and feeder disconnect. Wear appropriate Personal Protective Equipment (PPE) and open the control enclosure. Test for power on the incoming side of the disconnect using a volt meter.

  2. Prepare the Control Enclosure

    Remove the existing disconnect from the control enclosure. Seal the existing hole with a Hoffman hole seal and cover all components in the control enclosure to protect them.

  3. Mount the Sequestr Enclosure

    Remove the subpanel from the Sequestr enclosure. Drill a hole for the power line entrance and hang the Sequestr enclosure on the control enclosure using M6x16mm bolts. Secure it with M6x16mm washer head cap screws from inside the control enclosure.

  4. Install Circuit Breaker/Disconnect Switch

    Drill mounting holes for the circuit breaker or disconnect switch on the panel. Install the device according to the manufacturer's instructions and secure the panel back into the Sequestr enclosure.

  5. Connect Wiring

    Install conduit and wires to the incoming side of the circuit breaker/disconnect switch in the Sequestr enclosure. Ensure all connections are secure and properly insulated.

  6. Power Up the System

    Remove any protective coverings, ensure the operator handle is in the 'OFF' position, and securely close both the Sequestr and control enclosure doors. Turn on the feeder disconnect switch and then flip the operator handle to the 'ON' position.
