Option A: Near the bottom of the hoistway, you will find the travel cable and hoistway cable coiled up. Unwrap both cables and feed them to the desired exit point, through the raceway to the machine room.
Option B: The traveling cable and hoistway cable are terminated in a junction box at the bottom of the hoistway, and extra lengths of cable are supplied. Cut the cables to the precise length you need and wire them between the terminal box and the controller.
With a modular machine room, all gutter connections are precut and supplied. With a site-built machine room, you supply the gutter and conduit from the hoistway to the controller, controller to power unit, and controller to disconnects.
