I'm trying my first DIY electronics project. Here it is:
(assuming you live in the US and you are connecting this to 120 volts) The black wire in a power cord (or the narrow flat slot in the receptacle) is the wire that has voltage with respect to ground, called "hot". It would connect to the 120 volt orange transformer wire.
The white wire in a power cord (or the wide flat slot in the receptacle) carries load current, but is grounded back at the power panel, so it has very little voltage with respect to ground (only the wire drop caused by current passing through the wire). It connects to the white wire on the transformer.
The green wire in a power cord (or the round hole in the receptacle) is safety ground, which does not carry load current, and is grounded back at the power panel. No connections are shown for it, in this schematic, but if you bolt the transformer core down, it would be connected to one of those bolts.
Be sure to well tape all wires not used, as well as the connections you make. There will be lots more voltage on some of the unused wires than there are on the ones you connect. The black/white (probably black wire with white stripe) may have the highest voltage.
This advice is worth what you paid for it.
This first DIY project is a potential killer. Be very careful to touch no part of this thing when it is powered. If you kill yourself, please don't sue me.
from their website:
Core and coil ballasts are insulated with a varnish-like material. This material must be penetrated at the point where the ground connection is made to ensure a good connection. This connection can be made when mounting the ballast to the luminaire, by using a star washer in combination with one of the mounting bolts.
that's how you connect the green wire.
