Basic Wiring for Motor ContolWiring diagrams show the connections to the controller. Wiring diagrams, sometimes called “main” or “construc- tion” diagrams, show the actual connection points for the wires to the components and terminals of the controller. They show the relative location of the components. They can be used as a guide when wiring the controller.

Control Wiring The most common use of 3 wire control is a Start/Stop control. See image below for an example of 3 wire control being used to pull in a contactor to start a 3 phase motor.
Seven design diagrams that every HV substation engineer ...Wiring diagrams show the interconnection of the multicore cables, for example, between the switchgear and the associated control panels, and the routing of individual wires to the equipment installed in the relay and control panels. These diagrams are required to facilitate the wiring of the measurement, protection and control equipment at the substation construction stage. The wiring should be carried out in accordance with the layout shown in the AC and DC diagrams.
INSTALLATION INSTRUCTIONS AND OPERATION MANUALCONTROL WIRING If the door is not visible from the control station, or if any device other than the control station is used to activate the door, an entrapment protection device must be installed on the door. Failure to install an entrapment protection device may result in serious injury or death to person(s) trapped beneath the door. 1.
HANDHAND-OFF-AUTOMATIC CONTROLS Recognize hand-off-automatic switches on a schematic diagram. Hand-off-automatic controls are used to permit an operator to select between automatic or manual operation of a motor. The circuit shown in Figure 27–1 permits a motor to be operated by a float switch or to be run manually. The switch is shown as a single-pole…
