A wiring diagram is a simplified conventional pictorial representation of an electrical circuit. It shows the components of the circuit as simplified shapes, and the power and signal connections between the devices.
A wiring diagram usually gives information about the relative position and arrangement of devices and terminals on the devices, to help in building or servicing the device. This is unlike a schematic diagram, where the arrangement of the components' interconnections on the diagram usually does not correspond to the components' physical locations in the finished device. A pictorial diagram would show more detail of the physical appearance, whereas a wiring diagram uses a more symbolic notation to emphasize interconnections over physical appearance.
A wiring diagram is often used to troubleshoot problems and to make sure that all the connections have been made and that everything is present.
Architectural wiring diagrams show the approximate locations and interconnections of receptacles, lighting, and permanent electrical services in a building. Interconnecting wire routes may be shown approximately, where particular receptacles or fixtures must be on a common circuit.
Wiring diagrams use standard symbols for wiring devices, usually different from those used on schematic diagrams. The electrical symbols not only show where something is to be installed, but also what type of device is being installed. For example, a surface ceiling light is shown by one symbol, a recessed ceiling light has a different symbol, and a surface fluorescent light has another symbol. Each type of switch has a different symbol and so do the various outlets. There are symbols that show the location of smoke detectors, the doorbell chime, and thermostat. On large projects symbols may be numbered to show, for example, the panel board and circuit to which the device connects, and also to identify which of several types of fixture are to be installed at that location.
A set of wiring diagrams may be required by the electrical inspection authority to approve connection of the residence to the public electrical supply system.
Wiring diagrams will also include panel schedules for circuit breaker panelboards, and riser diagrams for special services such as fire alarm or closed circuit television or other special services.

The control switch (not supplied) should be a momentary center off SPDT type. The diagram included with the unit assumes a specific wiring harness, as such it may be confusing for general application. I've included my own diagram for added clarity, including the interior of the black box. NOTE: The Contactor relay coils draw approximately 3A @ 12V.
The wiring diagram for connecting thee phase motor to the supply along with control wiring is shown in figure below. This is a start stop push button control schematic which includes contactor (M), overload relay, control transformer, and push buttons. The contactor contains large load contacts that are intend to handle large amount of current.

4 pole contactors for power switching. Reliability where and when most needed. ABB's AF 4 pole contactor range is a complement to the family of 3 pole AF contactors and motor protection equipment.
The principal difference between a contactor and a motor starter it that a motor starter contains overload relays and a contactor does not. ... Anothername for a schematic diagram is a wiring diagram. ... The circuit is completed through the coil. When jogging with a control relay on a reversing starter, while the relay is energized, ____.
Try checking for line voltages at the "line" (source) side of the contactor, between terminals 1 and 2, 2 and 3, and 1 and 3, with the contactor energized (motor is supposed to be running). I'll leave it to you to explain why this is a good place to check first.
The fuse, reverse contactor, main contactor, and the throttle box came with the custom kit that I linked in the previous step. The contactors and fuse are sold in 24v, 36v, 48v, based on what system you want to go with. The lugs and 4 guage wire were bought here. It is safe to buy 4 guage wire in order to make sure that the wiring can handle ...
