Secure the cable reeler with the nylon cable running out the top pointing towards the inside of the boom, mount using four M8 bolts in each corner. Extend the nylon cable and anchor it to the inside boom section. Connect a normally closed switch to the 2-Pin connector on the cable reeler. The switch should be closed when the boom has been fully retracted (stowed). Connect the supplied 4 metre M12 Circular connector cable to the connector on the cable reeler. Run the cable to the display housing and connect into either of the M12 female connectors.
