This guide provides instructions for mounting and securing the MBG030302PC MultiboxG enclosure.

Estimated time: 30m

Tools needed:

Screwdriver, Drill (if mounting directly)

Supplies needed:

Mounting screws, DIN rail (optional, depending on mounting method)

  1. Select Mounting Location

    Choose a suitable location for the MBG030302PC enclosure. Ensure the location is free from excessive moisture, extreme temperatures, and physical damage. Refer to the datasheet for specific environmental limitations.

  2. Prepare for Mounting

    Determine the mounting method. If using a DIN rail, ensure the correct size DIN rail is installed. If mounting directly, mark the enclosure's mounting hole locations on the surface.

  3. Mount the Enclosure

    If using a DIN rail, slide the enclosure onto the rail and secure it. If mounting directly, drill pilot holes at the marked locations and use appropriate screws to fasten the enclosure to the surface. Ensure the enclosure is securely attached and level.

  4. Close the Enclosure

    Place the cover onto the enclosure base, ensuring the gasket is properly seated. Secure the cover using the provided corner screws. If using quick-release screws, turn them a quarter turn to lock.
