Step-by-Step Instructions

  • Mount the two Din Rails in the enclosure using the supplied hardware

  • Mount the Top Rail Components

    • A SS2 Spacer goes on the left end of the rail

    • The Shelly Pro 1 UL mounts next to the spacer on the left side

    • A SS2 Spacer mounts next to the Shelly Pro 1 UL holding it in place

    • A SS2 Spacer mounts roughly 1.5” away from the previous SS2 Spacer

    • The Shelly Contactor mounts up against the previous SS2 Spacer

    • A SS2 Spacer mounts next to the Shelly Contactor holding it in place

    • A DK2.5NC-PE ground terminal mounts towards the end of the right side of the din rail, you should have roughly ¼” of separation between in and the SS2 Spacer you just installed

      • The bottom connector of this terminal will connect to the ground output of the DK2.5NC-PE on the bottom rail

      • When the screws on the terminals are tightened the terminals will bite into the rails

  • Mount the following components to the bottom rail, in this order (from left to right)

    • SS2 Spacer

    • (1) DK10N-RD Terminal

      • The top connector on this terminal gets connected to the (R3) terminal of the contactor

    • (1) DK10N-BK Terminal

      • The top connector on this terminal gets connected to the (R1) terminal of the contactor

    • SS2 Spacer

      • This will hold the output terminals and connections in place

    • (2) DK10N-BK Terminals (connected by a two-position jumper)

      • One terminal of each will connect to the (L) terminal of the Shelly Pro 1 and the (R2) terminal of the contactor

      • The bottom terminal of one of these two terminals will be connected to the Phase A Line Voltage input

    • DK10N-RD Terminal

      • The top terminal will connect to the (R4) terminal of the contactor

      • The bottom terminal will be connected to the Phase B input

    • (2) DK10N Terminals (connected by a two-position jumper)

      • One terminal of each will connect to the (I) terminal of the Shelly Pro 1 and the (A2) terminal of the contactor

      • One of the bottom terminals will connect to the (N) terminal of the Shelly Pro 1 the other will be the Neutral input

    • SS2 Spacer

      • This will hold the completed terminal block in place

    • A DK2.5NC-PE ground terminal mounts towards the right-hand side of the rail

      • The top connector of this terminal will connect to the bottom connector of the DK2.5NC-PE terminal on the top rail, the bottom connector will connect to incoming ground

Tips & Tricks

  • Use wire appropriate to your application

  • Ground terminals need to be securely fastened to the rail

  • All wiring going in and out of the enclosure must pass through a strain relief

  • When routing wires in the enclosure zip ties and adhesive zip tie mounts can be helpful

  • Spacers should be used to not only hold devices in place but also to separate components

  • All screw terminals should be properly tightened, if you feel like you are using too much force, you are, and it will result in damaged components

  • Washers are included with the hardware to mount the din rails, these must be used 

  • Using stranded wire of the appropriate size is generally preferable to using solid core.
