Connect the 25-Way remote connector into socket on rear panel (factory wired
to bridge external interlock)
 Connect the earth stud on the rear panel to a safe reliable earth using a
green/yellow insulated wire (14-gauge minimum) which should be as short as
practical.
 Screw the cable connector on to the RF Output connector on the generator.
Attach the other end of the cable to a proprietary 50-Ohm resistive load capable
of 4000 Watts dissipation or a load of different or complex impedance connected
via a suitable RF impedance matching network.
 Connect the generator to the 3 Phase mains supply using the supplied mains
connector. Always ensure that this connector is easily accessible. This generator
operates from voltages in the range of 380V to 415V at 50 or 60Hz without the
need for adjustment.
 Ensure Pulse/CW switch on the front panel is in the CW position
 Switch on line breaker on front panel. Front display, and RF Off light should
illuminate.
 Rotate power set control to zero, press RF On. Rotate power set control towards
maximum and output power should increase. Continue to rotate control to
maximum and check that maximum obtainable power is correct. Press RF Off.
Other rear panel connectors are:
AMN Readout (Optional) – This connection is used when the capacitor positions
and dc developed bias voltage are to be displayed on the generator display. This
can only be used if a suitably equipped CPS automatic impedance matching network
is being used.
