Follow this guide to learn how to install - Place the Cable Node Expander at the optimal installation location using the magnetic foot mount to secure it. Adjust the foot mount so it lines up where the bottom of the foot mount is aligned with the downward slope of the bin roof. You may secure the foot mount in place with a self-tapping screw; however, it is not necessary. The magnetic foot mount provides a secure installation without needing a self-tapping screw in most cases. ![](https://knowledge.opisystems.com/hs-fs/hubfs/image-png-Oct-26-2026-05-08-26-1488-PM.png?width=378&height=532&name=image-png-Oct-26-2026-05-08-26-1488-PM.png) - Once the Cable Node Expander is installed, open the lid of the node by unclipping the latch. Keep your hands and face clear of the Cable Node Expander as once the latch is unclipped the node will open on its own. The Cable Node Expander will remain open until you close it  ![](https://knowledge.opisystems.com/hs-fs/hubfs/image-png-Oct-26-2026-05-12-41-2206-PM.png?width=364&height=616&name=image-png-Oct-26-2026-05-12-41-2206-PM.png) - Run the 3-wire cable up through the access port on the bottom of the Cable Node Expander. Once it is secure, establish a connection to the terminal on the Cable Node Expander circuit board. - ![](https://knowledge.opisystems.com/hs-fs/hubfs/image-png-Oct-26-2026-05-15-27-9219-PM.png?width=559&height=619&name=image-png-Oct-26-2026-05-15-27-9219-PM.png) - Close the lid and clip the latch back into place on the Cable Node Expander. Tighten to secure the access port on the bottom of the cable node expander board. - Secure a 1’ length of 3-wire cable with a drip loop to the foot mount of the Cable Node Expander.  ![](https://knowledge.opisystems.com/hs-fs/hubfs/image-png-Oct-26-2026-05-16-59-7644-PM.png?width=301&height=400&name=image-png-Oct-26-2026-05-16-59-7644-PM.png) - Run the 3-wire cable along the bin roof to the Primary/Secondary Node installation location, securing the wire with p-clips and self-tapping screws every 3’  ![](https://knowledge.opisystems.com/hs-fs/hubfs/image-png-Oct-26-2026-05-17-43-1395-PM.png?width=610&height=505&name=image-png-Oct-26-2026-05-17-43-1395-PM.png) - Once the 3-wire cable reaches the Primary/Secondary Node, secure a 1’ length of communication cable with a drip loop to the foot mount of the Primary/Secondary Node.  ![](https://knowledge.opisystems.com/hs-fs/hubfs/image-png-Oct-26-2026-05-19-27-9982-PM.png?width=313&height=447&name=image-png-Oct-26-2026-05-19-27-9982-PM.png) - Open the lid of the node by unclipping the latch.

The Primary/Secondary Node will remain open until you close it.  ![](https://knowledge.opisystems.com/hs-fs/hubfs/image-png-Oct-26-2026-05-20-00-0592-PM.png?width=355&height=466&name=image-png-Oct-26-2026-05-20-00-0592-PM.png) - Run the other end of the 3-wire cable up through the access port on the bottom of the Primary/Secondary Node. Once it is secure, establish a connection to the terminal on the Primary/Secondary Node circuit board.  ![](https://knowledge.opisystems.com/hs-fs/hubfs/image-png-Oct-26-2026-05-21-39-9053-PM.png?width=406&height=469&name=image-png-Oct-26-2026-05-21-39-9053-PM.png) - IN: Connection point for wire from Primary/ Secondary Node - OUT: Connection point to additional expander or headspace sensor on last expander ![](https://knowledge.opisystems.com/hs-fs/hubfs/image-png-Oct-26-2026-05-15-27-9219-PM.png?width=559&height=619&name=image-png-Oct-26-2026-05-15-27-9219-PM.png) - Nodes can run on constant 12V line power, not just solar.
