Answer for USA, Canada and countries running a 60 Hz supply service.
This is for a single phase air compressor whose magnetic contactor's coil voltage is the same as the supply line voltage. Take a wire from one of the line terminals L1 to one side of the contactor coil. Take another wire from the second line terminal L2 and put it to one side of a N.C. contact on the magnetic contactor's overload block. From the other side of the N.C. contact on the O/L block take a wire to the N.C. terminal on the pressure switch. From the other side of the N.C. contact on the pressure switch terminal connect the wire to the other side of the magnetic contactor's coil.
As always, if you are in doubt about what to do, the best advice anyone should give you is to call a licensed electrician to advise what work is needed.
Before you do any work yourself,
on electrical circuits, equipment or appliances,
always use a test meter to ensure the circuit is, in fact, de-energized.

if the compressor is Running you are low on freon, if its not then you have a electrical problem
Your compressor is a dual voltage compressor. The original installer followed the instructions to switch it (probably internally) to the 230 volt setting or to internally wire it for that voltage. The label or information plate on the unit may only indicate the higher voltage rating. You don't have to do anything.
an ubnloader valve release the pressurised air from the compressor building insinde the compressoe, & a secondry valve called check valve ensure that air does not flow out during unloader valve realse the pressure.
You could use an air chuck if you have a compressor or you might be able to get by with a can of air that's used for cleaning computer keyboards. There usually isn't too much gunk in there.
Movies can be exported directly from Final Cut without the use of Compressor.
The positive wire on a 1984 Mercedes 380 SL for the AC compressor is the green wire. It provides power to run the compressor when the air conditioner is turned on by the driver.
In a '99 Chevy Suburban, the hot wire to the AC compressor is usually the dark green wire. However, it's always best to consult the vehicle's wiring diagram or a professional to confirm the correct wire before making any modifications.
For air ride compressor Its a 5 or 6 wire electronic relay with a heat sink mounted on the compressor bracket.
If the compressor will not come on at all, it is not because the system needs charging. Check for a blown fuse, disconnected wire at the compressor, or a defective compressor clutch.
There are many reasons why an air conditioning compressor might not turn off. There is likely a wire that is not connected properly.
locate compressor on left inner fender under air filter box which will need to be removed unplug wire at compressor there are three nuts holding the compressor in. You get at them from under the car. lift out old compressor.
Common wire of the potential relay goes to the compressor contactor. (5) Start wire of the potential relay goes to compressor run capacitor. (2) Run wire of the potential relay goes to the start capacitor. (1)
Check the air compressor for short There are only a few wire's running to your air compressor and if none of those are causing the problem you are going to have to try and get under the rear of the car where the two wiring harness's are at each air bag and start from there working towards the front to try and find a loose wire or a bad spot. other than that your bags may have leaked causing your compressor to work over time and just blown the fuse and also wore out the compressor.
The conclusion of and air compressor is a supply of air. The air compressor generates air that is stored in a tank.
I'm Guessing that your talking about the A/C compressor, in which there are 1 or 2 wires going to the clutch. Disconnecting this wire(or 2) will disable the compressor clutch stopping the compressor from working.
