Supply the electronic board
The thyristor unit, to work, requires a voltage supply for the electronic boards of 24Vdc 1A on Terminal M1 (5, 6)
and the Synchronization signal between terminals 1 and 3.
The voltage used on Terminal 1 and 3 must be the same of load voltage (L1-L2/N).
Warning: Before connecting or disconnecting the unit check that power and control cables
are isolated from voltage sources.
