Power Requirements
This is a safety class 1 product (provided with a protective earth terminal). A non-interruptible safety
earth ground must be provided from the main power source to the Waveguide Switch Driver power
input terminals and power cord. Whenever the safety earth ground has been impaired, the
instrument must be made inoperative and secured against any unintended operation. If this
instrument is to be energised via an autotransformer (NOT RECOMMENDED) for voltage
reduction, make sure that the common terminal is connected to the earth pole of the power source.
