WARNING — These devices are designed to be operated at lethal voltages and energy levels. Circuit designs
that embody these components must conform with applicable safety requirements. Precautions must
be taken to prevent accidental contact with power-line potentials. Do not connect grounded test
equipment.
The use of an isolation transformer is recommended during circuit development and breadboarding.
