Connecting the ground terminal
For the ground connection, see "Figure 3-5 Grounding the system" and securely connect the
system to ground.
Warning
High voltages (several kilovolts) are generated by resonance in the matching box. You may get an
electric shock if the system is not properly grounded. Always ground the system. Wire the ground
so that the matching box's ground resistance is 10
Ω
or less. According to Japanese standards,
Class A grounding in Article 18 of the Electrical Equipment Standards is applicable. Wire the RF
power supply's ground (E) terminal for Class D grounding (Class A grounding when output is 5.0 kW
or higher).
