ENGLISH
ATTENTION
Do not carry out dielectrical test or partial discharge on the electric machine with
the device inserted, avoid if possible connecting the device directly to the
secondary of the transformer to protect, otherwise the transient overvoltage can
damage the device.
This is always clearer if the power supply voltage of the device is 230 VAC and in
case of condensers for the remaking.
