How to Install the RU-1-LP Residential DC String Transition Box

Install the RU-1-LP Residential DC String Transition Box to combine multiple DC strings into a single conduit.

Estimated time: 30m

Tools needed:

Screwdriver, Wire strippers, Pliers

Supplies needed:

Optional box bracket accessory, Racking system accessories, Wire connectors

  1. Choose Mounting Location

    Select a mounting location for the RU-1-LP. It can be mounted beneath the PV array using the optional box bracket accessory or adjacent to the array using racking system accessories. Ensure the location is suitable for outdoor use and allows for easy access to the DC strings.

  2. Mount the Enclosure

    Securely mount the RU-1-LP enclosure using the chosen accessory (optional box bracket or racking system accessories). Ensure the enclosure is firmly attached and oriented correctly for wiring access.

  3. Prepare DC Strings

    Identify the DC strings that will be connected to the RU-1-LP. Ensure the conductors are stripped to the appropriate length for the screw clamp terminals. Refer to the specifications for wire size ranges.

  4. Connect DC Strings

    Open the RU-1-LP enclosure. Connect each DC string to the designated screw clamp terminals. Use the provided 2-prong jumpers if combining strings within the box. Ensure all connections are tight and secure. Refer to the product's datasheet for specific terminal assignments and jumper configurations. Verify the maximum voltage and current ratings are not exceeded.

  5. Close and Seal Enclosure

    Carefully close the RU-1-LP enclosure, ensuring all wires are properly managed and not pinched. Secure the enclosure lid to maintain the NEMA 4X rating.
