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, wiring, and initial setup.

Estimated time: 1h

Tools needed:

Screwdriver, Wire strippers, Multimeter, Drill

Supplies needed:

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

  1. Power Down the System

    Turn off the local disconnect in the control enclosure and the feeder disconnect. Put on appropriate Personal Protective Equipment (PPE) and open the control enclosure.

  2. Prepare the Control Enclosure

    Remove the existing disconnect from the control enclosure and seal the hole with a Hoffman hole seal. 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, then hang the Sequestr enclosure on the control enclosure using M6x16mm bolts. Secure it with washer head cap screws from inside the control enclosure.

  4. Install the Circuit Breaker

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

  5. Connect Wiring

    Install conduit and connect wires to the incoming side of the circuit breaker in the Sequestr enclosure. Ensure all connections are secure.

  6. Power Up the System

    Remove any protective coverings, ensure the operator handle is in the 'OFF' position, close and latch both the Sequestr and control enclosure doors, then turn on the feeder disconnect switch and verify system operation.
