How to Install a A90PM78B Panel

This guide provides instructions for installing a A90PM78B panel into an enclosure. Ensure you select the correct panel size and mounting hardware for your specific enclosure type.

Estimated time: 30m

Tools needed:

Screwdriver, Drill (if mounting holes are not pre-drilled), Measuring tape

Supplies needed:

Mounting screws, Panel (A90PM78B), Enclosure

  1. Select the appropriate panel and mounting hardware

    Choose the A90PM78B panel that matches the dimensions and type of your enclosure. Refer to the product documentation for compatibility. Ensure you have the correct mounting screws and any necessary hardware (e.g., sealing washers) as specified for your enclosure and panel.

  2. Prepare the enclosure

    If your enclosure does not have pre-drilled mounting holes for the panel, carefully measure and mark the locations according to the panel's specifications. Drill the necessary holes. Ensure the enclosure is clean and free of debris before proceeding.

  3. Mount the panel

    Position the A90PM78B panel within the enclosure. Align the panel's mounting holes with the corresponding holes in the enclosure. Secure the panel using the appropriate mounting screws. For panels with flanges, ensure they are correctly seated against the enclosure walls.

  4. Verify panel security

    Gently test the mounted A90PM78B panel to ensure it is securely fastened and does not move. Check that all screws are tightened to the recommended torque, if specified, to prevent loosening over time. If the enclosure has a specific rating (e.g., NEMA or UL), ensure the installation maintains this rating by using any provided sealing hardware.
