Electrical circuit.
e VICTRIX Zeus electrical circuit is completely connected
to a microprocessor controlled card board that controls gen-
erator functions.
230 V AC circuit.
Safety devices and checks.
Some of the devices of control and safety on the circuit operate
at mains voltage (230 V AC) while the others at low voltage.
