fil WARNING:
Maintenance personnel must receive proper training before installing,
troubleshooting, or maintaining high-energy electrical equipment.
Potentially lethal voltages could cause death, serious personal injury, or
damage to the equipment. Ensure that all appropriate safety precautions
are taken.
& DANGER:
RISK OF DEATH OR BODILY INJURY. Disconnect and lockout/tagout all
sources of input power before working on this unit or anything
connected to it.

WARNING:
Leaving on the RF power after turning off the input power to the match
network may damage the unit.
Some ICP units can be operated using either the L match or the Gamma topology,
which allow two different load impedance ranges. By changing the capacitor's
interconnection, you can change the topology of the V arioMatch match network. See
Chapter 3, " Specifications" for a list of part numbers that support this. See
"Topologies" on page 2-4 for information abou t the L Match and Gamma topologies.
If your IPC V arioMatch match ne t work supports changing between L Match and
Gamma topologies:
• The default topo
l ogy, as shipped from the factory, is Gamma (Configuration A).
• Use the instructions in this section to change from Gamma to L match topo
l ogy.
• The load impedance ranges for each configuration are shown in the Smith
® charts
in the Technical Bulletin for your unit. Contact Global Services to obtain the
correc t Technical Bulletin.
To change topology, perform the tasks documented in the following sections:
•
"Tools Required to Change the Interconnection" on page 5-28
