    * Hotspot is a place with public WLAN coverage. Go to the smart phone's mobile-hotspot-connection settings to connect to the internet. The smart phone can then act as a router for other devices with Wi-Fi functionality, e.g. LK ArcHub, which must be connected.

  • Page 8: Space Required For Installing Lk Arctenna

    Position of LK ArcHub in the manifold cabinet in relation to LK ArcTenna EXCEPTION! In a manifold cabinet with a width of 1050 cm, the cable length of LK ArcTenna limits where LK ArcHub can be placed. Take into account the position of the electrical socket in the manifold cabinet.

  • Page 9: Position Of Lk Archub In Relation To The Flow Indicators

    NOTE! LK ArcHub’s position can be adjusted to the right or left if the cabinet is less than 1050 cm wide. Drill a hole in the panel where LK ArcHub is to be placed. Take into account the position of the electrical socket in the manifold cabinet.
