3.6.3 Special Requirements for Measurements with Higher Voltages outside the scope of
UL
Note
Above 300 V system voltage ratings are not permissable for UL!
Thus the following requirements for Measurements with Higher voltages without Voltage
Measurement Transformer (VT) are outside the scope of UL.
Measurements with higher voltages without VT are outside the scope of UL.
The following information applies to voltages U
