Terminal and Relay Diagrams

Thursday, September 17th, 2009

Well, now that I’m getting ready to hook up the high voltage, I feel good enough about my terminal block and relay hookup diagrams.  I’ve put it into a PDF for your viewing pleasure, and it can be found here: 914_AC24_Layout_V1.  I hope this helps with other people trying the same sort of madness.  😀

Wye a Motor?

Saturday, September 12th, 2009

Since I’m going to go with the higher voltage, I have to change the wiring of the motor from Delta to Wye (hence the bad joke in the title).

Getting to the wiring was challenging, since one of the hex bolts holding the protective plate was stripped during initial installation. Thanks to Sears, I now have some nice tools to remove stripped screws and bolts.  Fortunately, my wife went with me to the store, otherwise who knows what I would have ended up bringing home!  (called the “ooooh it’s shiny!” syndrome)

Once I got the wires exposed, I thought a before picture would help explain. Here is the Delta wiring:

And then after the rearrangement of wiring to Wye:

Now I have to put the cover back on, but that requires instant gasket goop to seal the wires in.  *sigh* Yet another trip to the store.

AC in progress

I’ve had a busy weekend adding in the plug and getting the wiring set up.  The plug is an interesting model – it will automatically eject the plug when the key is turned – very nice feature.

The AC is routed to the relay panel, the charger and to the EKM meter.  The EKM meter has a ring around the live wire to the charger so it can record how much power the charger is using.

Here’s a picture of the new plug.
