ENGLISH
ATTENTION
Don't effect dielectrical test or partial discharge on the electric machine
with the device inserted, avoid if possible to connect the device directly
to the secondary of the transformer to protect, otherwise the transient
overvoltage can demage 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.
TESTING CERTIFICATE
The testing procedure is made as follows:
• Push-buttons working.
• Relays testing contacts.
• Main mechanical checking.
• Calibration and linearization at +30°C and +150°C.
• Testing for 48 hours with variable power voltage supply.
Insulating testing between earth and relays at 2.5 KVAC for 60".
