Is anyone here using this ballast for 12K HMI in the UK or Australia? In the US they draw power from across phases for 240VAC so the wiring for this light there in effect does not have a neutral pole. Their 220V 100amp Bates stage plug has three pins, two "hot" and an earth pin. The ballast will work on Australian 240VAC 50Hz power.
In Australia, 240V is single phase. This means an active, neutral and earth. I will be having a qualified electrician hook this thing up via a Mareschal multipin plug for a test on a generator. Any info on which of the two "hot" pins in the military input connector on the ballast should be the neutral would be appreciated. The "A" pin is the earth, that much is stated on the appliance.
There are red and black internal connections and the earth connection is the traditional green/yellow, so my guess is the black would be preferred as the neutral. Both wires go individually directly to heavy duty bolted fuses, thence as far as I can determine to a DC rectifier. The info is required to make life easier for the electrician. I won't be touching it other than to blow dust and spiders out.
Any info will be appreciated.
