A modular machine room (MMR) has a fully assembled power unit and controller already installed and wired together, making piping and wiring easy.
Disconnects are also pre-installed and wired to the controller. The controller is wired into quick-connect plugs mounted on the bottom of the controller.
The traveling cable and hoistway cable are coiled up near the bottom of the hoistway. Unwrap both, then feed them through the exit point, through the raceway, to the machine room.
Plug the quick connects on the traveler and hoistway cables onto their mates in the controller.
