can greatly reduce installation time further since the wiring may be done at the factory it would be possible to verify that wiring was done correctly prior to shipment of the frame module and machinery the ends of the wiring may include releasable electrical connections to allow for easy disconnection and connection that requires reduced limited or no knowledge from an electrician similarly the junction box or panel may also include one or multiple releasable connections that are associated with the columns motors sensors and other controls these releasable connections may be specific to a particular wiring pattern for the controller so that incorrect wiring is avoided the junction box or panel may be located such that the controller can be connected thereto non symmetrical plugs and sockets and different shaped connectors that are designed to be compatible with certain wiring schematics are contemplated in order to reduce the likelihood of incorrect wiring if appropriate other types of connections may be considered part of the u201c electrical connection u201d for example an optical connection or others may be used for example to transmit sensor signals as necessary the conduit for the electrical connections may be embedded in the foundation or may be designed to be attached to the inner surface of the frame member 4 for example the conduit may run along the top of base plates 40 42 the conduit may also run along the frame members.
