12 Warranty rules
The CCT 440, CCT 441 and CCT 442 power units are covered by warranty for
a period of 1 year from the testing date indicated both on the label and in the
attached manual. The warranty is considered valid until it is sure that the
cause of a failure are due to production defects or wrong calibration of the
probes. We are not responsible for failures due to a wrong wiring of the
probes, tampering with the power unit or wrong supply voltage (for ex. 400
Volt AC).
13 Warning
Do not carry out dielectric strength or partial discharges tests on the electric
machines with the power unit inserted. Do not directly connect the power
unit to the secondary winding of the transformer to protect. Without
protection, when closing the switch placed downstream of the transformer,
there could be over voltages that can damage the device. The problem may
occur frequently when the supply voltage of the power unit is 230 V and if
there are power factor correction capacitors.
