How to Install the MB-PLKIT Multibox Enclosure

Guide for installing and preparing the MB-PLKIT Multibox series enclosure for use as an electrical junction or instrumentation enclosure.

Estimated time: 30m

Tools needed:

Screwdriver, Drill (if mounting holes are needed), Wire strippers, Pliers

Supplies needed:

Mounting hardware (screws, anchors), Grommets or conduit fittings (if using knockouts), Wire connectors

  1. Select Mounting Location

    Choose a suitable location for the MB-PLKIT enclosure. Consider environmental factors and accessibility. Refer to the datasheet for specific temperature and environmental ratings applicable to your model.

  2. Prepare Enclosure (if necessary)

    If using a model with knockouts (PCK, PSK, PCCTK, PSCTK), select the appropriate knockout locations for cable entry. Remove the knockouts using appropriate tools. Install grommets or conduit fittings as needed. For models without knockouts, plan your cable entry points.

  3. Mount the Enclosure

    Securely mount the MB-PLKIT enclosure to the desired surface using appropriate mounting hardware. Ensure the enclosure is level and firmly attached. For specific mounting instructions or back plate compatibility, refer to the product's datasheet.

  4. Install Internal Components (if applicable)

    If you are installing internal components such as back plates (e.g., MBBP series), do so now according to their specific instructions. Ensure any internal components are compatible with the enclosure size and type.

  5. Route Wiring

    Carefully route all necessary wiring into the enclosure through the prepared openings or knockouts. Use appropriate cable glands or fittings to maintain the enclosure's integrity.

  6. Connect Wiring

    Make all necessary electrical connections inside the enclosure using appropriate wire connectors. Ensure all connections are secure and comply with relevant electrical codes. Refer to any specific wiring diagrams or datasheets for your application.

  7. Close and Secure the Enclosure

    Ensure all internal wiring is properly managed and does not interfere with the gasket. Close the cover of the MB-PLKIT enclosure and securely fasten the corner screws. Verify that the gasket provides a continuous seal.
