such, connect the ground conductor of the power supply cable to the specific
terminal in the multipole socket and check the efficiency of your own grounding
system.

After having plugged in the power supply socket at the back of the machine, power
on the amplifier via the switchboard. The ON LEDs on both modules will turn on
and the forced cooling fans will start running. The LCD shows the first introductory

power values.
Turn on the exciter (at lowest power) and wait until it locks to the work frequency.
Once locked, increase power gradually and check the amplifier’s display. Increase
the exciter’s power until the amplifier’s output attains the desired value, max. 3000
watts for PJ3000M-C model, or 2500 watts for PJ2500M-C model, or 2000 watts
for PJ2000M-C model (keep in mind that due to the measurement digitalization
