How to Install the Sequestr External Disconnect Enclosure

This guide provides step-by-step instructions for installing the Sequestr external disconnect enclosure to an existing control enclosure, ensuring proper mounting, wiring, and configuration.

Estimated time: 1h

Tools needed:

Screwdriver, Drill, Volt meter, Wire strippers

Supplies needed:

Mounting screws, Hex nuts, Gasket, Terminal connectors, Hole seals

  1. Power Down the System

    Turn off the local disconnect installed in the control enclosure and ensure all power to the enclosure is off. Wear appropriate Personal Protective Equipment (PPE) before proceeding.
